An increasing amount of research focuses on integrating the Internet of Things and blockchain technology to address the requirements of traceability applications for Industry 4.0. However, there has been little quantitative analysis of several aspects of these new blockchain-based traceability systems. For instance, very few works have studied blockchain’s impact on the resources of constrained IoT sensors. Similarly, the infrastructure costs of these blockchain-based systems are not widely understood. This paper characterizes the resources of low-cost IoT sensors and provides a monetary cost model for blockchain infrastructure to support blockchain-based traceability systems. First, we describe and implement a farm-to-fork case study using public and private blockchain networks. Then, we analyze the impact of blockchain in six different resource-limited IoT devices in terms of disk and memory footprint, processing time, and energy consumption. Next, we present an infrastructure cost model and use it to identify the costs for the public and private networks. Finally, we evaluate the traceability of a product in different scenarios. Our results showed that low-cost sensors could directly interact with both types of blockchains with minimal energy overhead. Furthermore, our cost model showed that setting a private blockchain infrastructure costs approximately the same as that managing 50 products on a public blockchain network.

Peer-to-peer (P2P) energy management is one of the most viable solutions to incentivize prosumers in renewable energy microgrids. As the application of blockchain expends from the finance field to energy field, blockchain technology provides a new opportunity for distributed energy systems. However, a distributed energy system based on blockchains allows any node in the whole network to read data. In many application scenarios, user privacy cannot be effectively protected, and there is a security problem that the attack cannot be traced. In this paper, we propose an energy management mode based on a permissioned blockchain for a renewable energy microgrid. The novel permissioned blockchain framework uses entity mapping with a unique identity for each enterprise, natural person, or device, in order to avoid ineligible participants to join the microgrid. Each peer entity keeps the transaction information index of the whole network, but only keeps its own specific transaction information, so they can retrieve the transaction information of other peer entities but cannot obtain the details without permission. Moreover, this model could avoid communication delays and promote plug-and-play due to the distributed nature of the permissioned blockchain. The performance of the proposed method is evaluated with a demonstration program which is designed and deployed on a Hyperledger Fabric permissioned blockchain. Simulation results show the feasibility of the proposed method, and the model is conducive to the protection privacy and P2P energy management for decentralized energy systems.

The application of blockchain technology to the energy sector promises to derive new operating models focused on local generation and sustainable practices, which are driven by peer-to-peer collaboration and community engagement. However, real-world energy blockchains differ from typical blockchain networks insofar as they must interoperate with grid infrastructure, adhere to energy regulations, and embody engineering principles. Naturally, these additional dimensions make real-world energy blockchains highly dependent on the participation of grid operators, engineers, and energy providers. Although much theoretical and proof-of-concept research has been published on energy blockchains, this research aims to establish a lens on real-world projects and implementations that may inform the alignment of academic and industry research agendas. This research classifies 131 real-world energy blockchain initiatives to develop an understanding of how blockchains are being applied to the energy domain, what type of failure rates can be observed from recently reported initiatives, and what level of technical and theoretical details are reported for real-world deployments. The results presented from the systematic analysis highlight that real-world energy blockchains are (a) growing exponentially year-on-year, (b) producing relatively low failure/drop-off rates (~7% since 2015), and (c) demonstrating information sharing protocols that produce content with insufficient technical and theoretical depth.

Energy management and exchange have increasingly shifted from concentrated to hierarchical modes. Numerous issues have arisen in the decentralized energy sector, including the storage of customer data and the need to ensure data integrity, fairness, and accountability in the transaction phase. The problem is that in the field of the innovative technology of blockchain and its applications, with the energy sector still in the developmental stages, there is still a need for more research to understand the full capacity of the technology in the field. The main aim of this work was to investigate the state of the current research of blockchain technologies as well as their application within the field of energy. This work also set out to identify certain research gaps and provide a set of recommendations for future directions. Among these research gaps is the application of blockchain in decentralized storage, the integration of blockchain with artificial intelligence, and security and privacy concerns, which have not received much attention despite their importance. An analysis of fifty-seven carefully reviewed studies revealed that the emerging blockchain which provides privacy-protection technologies in cryptography and other areas that can be integrated to address users’ privacy concerns is another aspect that needs further investigation. Grid operations, economies, and customers will all learn from blockchain technology as it provides disintermediation, confidentiality, and tamper-proof transfers. Moreover, it provides innovative ways for customers and small solar generators to participate more actively in the electricity sector and to benefit from their properties. Blockchains are a rapidly evolving field of research and growth. A study of this emerging technology is necessary to increase comprehension, to educate the body of expertise on blockchains, and to realize its potential. This study recommends that future work investigates the potential application of blockchain in the energy sector as well as the challenges that face its implementation from the perspective of policy makers. This future approach will enable researchers to direct their focus to the case studies approach, which will facilitate and ease the application of blockchain technology.

Blockchain technology has revolutionized many industries and has great potential outside of finance. This paper explores blockchain's applications and challenges in agriculture, electricity, transportation, healthcare, and finance. Blockchain technology can track agricultural product origin, quality, and safety to improve supply chain transparency in agriculture. Blockchain can also reduce intermediaries, improve payment systems, and expand financing. Blockchain can enable decentralized electricity management, peer-to-peer energy transactions, and lower transaction costs. It could boost renewable energy integration, grid efficiency, and energy access for underserved communities. Blockchain technology can improve transportation supply chain visibility and reduce fraud by providing a shared, tamper-proof ledger to track goods and prevent unauthorized access. Blockchain can secure, interoperable, and improve patient privacy in healthcare. It could let patients share their health data with providers and researchers while protecting their privacy. Blockchain implementation is also tricky. Scalability, interoperability, compliance, and data privacy Blockchain solutions must handle large amounts of data, integrate with existing systems, comply with laws and regulations, and protect sensitive data. Further research and development are necessary to explore blockchain technology's possibilities in these fields fully.

Satisfying the world’s rapidly increasing demands in energy via the optimized management of available resources is becoming one of the most important research trends worldwide. When it comes to energy, it is very important to talk about decentralization, security, traceability and transparency. Thus, over the last few years, numerous research works have presented blockchain technology as the best novel business platform enabling a secure, transparent and tamper-proof energy management solution. In this paper, we conducted a systematic literature review (SLR) using the PRISMA framework of the different existing research studies related to the use of the blockchain technology in the energy sector, published between 2008 and 2021. We identified a total of 769 primary studies after intensive manual analysis and filtering, which we thoroughly assessed using various criteria to address six main research questions that covered the blockchain types, applications and platforms in the energy sector, the energy source types for which blockchain platforms are implemented, the emergent technologies that are combined to blockchain solutions, and the types of consensuses used in energy blockchains. Based on the collected survey data, we built a database to categorize the existing research works, identify research trends, and highlight knowledge gaps and potential areas for additional field study.

Purpose The purpose of this study is to formulate the most probable future scenario for the use of blockchain technology within the next 5–10 years in the electricity sector based on today’s experts’ views. Design/methodology/approach An international, two-stage Delphi study with 20 projections is used. Findings According to the experts, blockchain applications will be primarily based on permissioned or consortium blockchains. Blockchain-based applications will integrate Internet of Things devices in the power grid, manage the e-mobility infrastructure, automate billing and direct payment and issue certificates regarding the origin of electricity. Blockchain solutions are expected to play an important big role in fostering peer-to-peer trading in microgrids, further democratizing and decentralizing the energy sector. New regulatory frameworks become necessary. Research limitations/implications The Delphi study’s scope is rather broad than narrow and detailed. Further studies should focus on partial scenarios. Practical implications Electricity market participants should build blockchain-based competences and collaborate in current pilot projects. Social implications Blockchain technology will further decentralize the energy sector and probably reduce transaction costs. Originality/value Despite the assumed importance of blockchain technology, no coherent foresight study on its use and implications exists yet. This study closes this research gap.

This research paper represents an investigation of blockchain applicability in the Swedish energy market. The paper also attempts to explore the numerous claims and benefits surrounding this technology. Overall, the blockchain platform presents an innovative opportunity for energy to be bought and sold on the market in a new way that is providing consumers with greater efficiency and control over their energy sources. The platform is also set to integrate different types of data such as energy prices, usage, marginal costs, legal compliances etc., with the purpose of providing a better service than the platforms that exist today. To investigate these claims, firstly, the blockchain technology, its purpose, and function is explained. Secondly, the paper explores relationship and application in the energy market. Existing literature has been examined in order to provide a foundation when it comes to technological application. Lastly, the Swedish energy market has been considered and if the technology would make a difference. The interviews with experts have been conducted to get an inside look into the actual reality of this technology. Overall, the experts did not have a strong word to give about the possible application of the technology in the Swedish energy market. The technology does have potential but it is simply in too early stages of development and the obstacles are more significant than the previously promised benefits.

Blockchain is a Distributed Ledger Technology that was popularized after the release of Bitcoin in 2009 as it was the first popular blockchain application. It is a technology for maintaining a digital and public ledger that is decentralized, which means that no single authority controls nor owns the public ledger. The ledger is formed by a chain of data structures, called blocks, that contain information. This ledger is shared publicly in a computer network where each node is called a peer. The problem that arises is how to make sure that every peer has the same ledger. This is solved with consensus mechanisms which are a set of rules that every peer must follow. Consensus mechanisms secure the ledger by ensuring that the majority of peers can reach agreement on the same ledger and that the malicious minority of peers cannot influence the majority agreement. There are many different consensus mechanisms. A problem with consensus mechanisms is that they have to make a trade-off between low energy consumption and high security. The purpose of this report is to explore and investigate the relationship between energy consumption and security in consensus mechanisms. The goal is to perform a comparative study of consensus mechanisms from an energy consumption and security perspective. The consensus mechanisms that are compared are Proof of Work, Proof of Stake and Delegated Proof of Stake. The methodology used is literature study and comparative study by using existing work and data from applications based on those consensus mechanisms. The results conclude that Proof of Work balances the trade-off by having high energy-consumption and high security, meanwhile Proof of Stake and Delegated Proof of Stake balance it by having low energy consumption but lower security level. In the analysis, a new factor arose, decentralization. The new insight in consensus mechanisms is that decentralization and security is threatened by an inevitable centralization where the ledger is controlled by few peers.
Blockchain är en så kallad distribuerad huvudbok teknologi som fick ett stort genombrott med den populära blockchain applikationen Bitcoin i 2009. Teknologin möjliggör upprätthållandet av en digital och offentlig huvudbok som är decentraliserad, vilket betyder att ingen ensam person eller organisation äger och kontrollerar den offentliga huvudboken. Huvudboken i blockchain är uppbyggt som en kedja av block, dessa block är datastrukturer som innehåller information. Huvudboken distribueras i ett nätverk av datorer som kallas för noder, dessa noder ägs av en eller flera personer. Problemet är att alla noderna i nätverket måste ha identiska huvudbok. Detta problem löses med en uppsättning av regler som noderna måste följa, denna uppsättning kallas för konsensus mekanism. Konsensus mekanismer säkrar huvudboken genom att möjliggöra en överenskommelse bland majoriteten av noderna om huvudbokens innehåll, och ser till att oärliga noder inte kan påverka majoritetens överenskommelse. Det finns flera olika konsensus mekanismer. Ett problem med konsensus mekanismer är att de är tvungna att göra en avvägning mellan låg energianvändning och hög säkerhet. Syftet med denna rapport är att undersöka och utreda relationen mellan energianvändning och säkerhet i konsensus mekanismer. Målet är att utföra en komparativ analys av konsensus mekanismer utifrån energianvändning och säkerhet. Konsensus mekanismerna som jämförs är Proof of Work, Proof of Stake och Delegated Proof of Stake. Metodologin som används är litteraturstudier och komparativ analys med hjälp av existerande metoder och data från applikationer som använder konsensus mekanismerna. Resultatet visar att Proof of Work väljer hög säkerhet på bekostnad av hög energianvändning, medan Proof of Stake och Delegated Proof of Stake väljer låg energianvändning men på bekostnad av lägre säkerhet. Analysen ger en ny inblick som visar att centralisering är en oundviklig faktor som hotar säkerheten.

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 10.0px Helvetica} Blockchain is a distributed ledger technology enabling digital transactions without the need for central governance. Once transactions are added to the blockchain, they cannot be altered. One of the main challenges of blockchain implementation is how to create a scalable network meaning verifying many transactions per second. The goal of this thesis is to survey different approaches for scaling blockchain technologies. Scalability is one of the main drivers in blockchain development, and an important factor when understanding the future progress of blockchain. The energy sector is in need of further digitalisation and blockchain is therefore of interest to enhance the digital development of smart grids and Internet of Things. The focus of this work is put on a case study in the energy sector regarding a payment system for electrified roads. To research those questions a qualitative method based on interviews with blockchain experts and actors in electrified roads projects was applied. The interviews were processed and summarised, and thereafter related to map current developments and needs in the blockchain technology. This thesis points to the importance of considering the trilemma, stating that blockchain can be two of three things; scalable, decentralised, secure. Further, Greenspan’s criteria are applied in order to recognise the value of blockchain. These criteria together with the trilemma and understanding blockchain’s placement in the hype cycle, are of value when implementing blockchain. The study shows that blockchain technology is at an early stage and questions remain regarding future business use. Scalability solutions are both technical and case specific and it is found that future solutions for scaling blockchain are emerging.

World energy systems are going through a continuous change. The focus has been shifted from large thermal or hydal power generation to small distributed generation, mainly based upon renewable energy systems. This transition is also backed by some governments. There have also been significant improvements in grid technology, and modern-day smart grid can provide real time bi-directional flow of data i.e. “real time energy deficit and surplus, and also real time prices to both producers and consumers. Smart grid can also accommodate intermittent small suppliers of electricity. This shift in energy generation policy and improvement in grid technology has opened ways for small scale energy producers and consumers to share energy with each other. It has also opened ways to purchase or sale energy to unknown peers over a smart grid. Need has been felt to store these transactions among peers in a secure, non-alterable yet quickly accessible way. Blockchain technology offers to provide this secure, unalterable yet quickly accessible ledger. In this study this transition process and role of blockchain technology for future energy systems has been historically reviewed. It has been found out that on top of keeping record of Peer to Peer transactions, blockchain technology can fill many other purposes. However, technology is still not matured for large scale projects, Research projects are underway to decrease the large time and energy consumption for block building computational processes yet keeping them safe and reliable.

The popularity of blockchain technologies increases with a significant rise in the price of cryptocurrency in 2017, which drew much attention in the academia and industry to research and implement new application or new blockchain technology. Many new blockchains have emerged over the last year in a broad spectrum of sectors and use cases including IOT, Energy, Finance, Real estate, Entertainment, etc.Despite many exciting research and applications have been done, there are still many areas worth investigating, and implementation of the blockchain based distributed application are still facing much uncertainty and challenging since blockchain is still an emerging technology. Meanwhile, the energy sector is under a transition to be digitalized and more distributed. A global technology revolution has disrupted the conventional centralized power system with distributed resources and technologies, like photovoltaic units (PV), batteries, electric mobilities, etc. The citizens then have control of their generation and consumption profiles.The purpose of this master thesis is to explore existing blockchain technology, and smart contracts such as IOTA, NEO, Ethereum Tobalaba, which can be adapted in the energy sector. Within this thesis, blockchain and the smart contract is proposed as a way of building distributed applications for a p2p transaction use case in the energy asset management platform. A design science research methodology is applied for the artifact development and evaluation for the research result. The design was implemented on Ethereum and tested on Tobalaba public network with ether and GAS. The evaluation shows the artifact for the p2p transaction in energy asset management platform fulfill the completeness, and correctness of the design requirement. The result of the performance test on Tobalaba networks shows a correlation between GAS consumption and transaction time.

The changing nature of the energy grid in recent years has prompted key stakeholders to think of ways to address incoming challenges. Transactive energy is an approach that promises to dynamically align active grid elements coming up in the previously inactive consumers' side to achieve a reliable and smarter grid. This work models the distribution grid structure as a combination of microgrids. A blockchain-in-the loop simulation framework is modelled and simulated for a residential microgrid using power system simulators and transactive agents. Blockchain smart contracts are used to coordinate peer-to-peer energy transactions in the microgrid. The model is used to test three market coordination schemes: a simple auction-less scheme, an auction-less scheme with a normalized sorting metric and an hour ahead single auction scheme with penalties for unfulfilled bids. Case studies are presented of a microgrid with 30 homes, at different levels of solar and energy storage penetration within the microgrid, all equipped with responsive and unresponsive appliances and transactive agents for the HVAC systems. The auction-less scheme with a normalized sorting metric is observed to provide a fairer advantage to smaller solar installations in comparison to the simple auction-less method. It is then concluded that the auction-less schemes are most beneficial to users, as they would not need sophisticated forecasting technology to reduce penalties from bid quantity inaccuracies, as long as the energy mix within the microgrid is diverse enough.

Blockchain, a distributed ledger technology, became publicly known when the cryptocurrency Bitcoin was introduced in 2009. As the financial value of cryptocurrencies increased, the interest for blockchain grew, leading other sectors to explore if blockchain could be used in other areas as well. One of these areas was the energy sector where the technology was predicted to transform the market by cutting out intermediaries with the use of peer-to-peer electricity trading. Today there are few successful commercial blockchain projects and the blockchain-hype is seemingly decreasing. It is, however, unclear if this is a natural part of the innovation process that follows the Gartner hype cycle or if the energy sector will reject the technology. This thesis aims to investigate the value characteristics of blockchain in the electricity system, and if these can add value to the future electricity system in Sweden. Firstly, to answer this question, a literature review is conducted to explore how blockchain has been applied in the electricity sector in earlier studies and what value the technology offered. Secondly, an interview study with 28 participants was conducted with the purpose to understand future predictions of how the electricity system in Sweden will be configured, and the energy sector’s understanding of blockchain technology. The literature concluded that blockchain could particularly offer these five value characteristics: 1) transparency 2) decentralisation 3) immutability 4) traceability and 5) P2P interaction. Furthermore, did the interview study result in a multi-level perspective analysis and proposed that the electricity system in Sweden is facing a reconfiguration pathway driven by the landscape pressures, consisting of electrification, digitalisation, decarbonisation and a potential nuclear phaseout. Moreover, this study has found that the electricity system in Sweden is fronting a regime transition from a centralised system with stable generation and consumptionbased production, to a decentralised system with more intermittent generation and productionbased consumption. In this regime shift, new challenges will occur, and the common denominator for these solutions is a more flexible electricity system, i.e. that the demand-side needs to become more flexible in consumption. The thesis has found that blockchain can provide the most value for the electricity system by functioning as a layer of governance on a potential local flexibility market. The flexibility will be decentralised and offered by both consumers and industries. The actors will, consequently, need an authentication process to confirm if flexibility providers can provide flexibility at a given moment. The five value characteristics do consequently have potential to provide a solution to this specific challenge. The thesis does, however, conclude that both the flexibility market, emerging business models and blockchain technology are not mature enough today. Accordingly, it is too early to decide if blockchain is the best-suited technology to serve this purpose, even if the value characteristics indicate potential.
Blockchain är en distribuerad databasteknologi som blev känd för den stora allmänheten när kryptovalutan bitcoin lanserades 2009. När intresset och värdet på kryptovalutor i allmänhet, och bitcoin i synnerhet, ökade blev även andra sektorer intresserade av blockchain-teknologin. En av dessa sektorer var energibranschen där visionen var att teknologin skulle eliminera mellanhänder genom att erbjuda el-transaktioner direkt mellan två personer med hjälp av exempelvis solpaneler. Idag är det däremot få, eller inget projekt, som blivit kommersiellt gångbart och den en gång stora tilltron på att blockchain skulle revolutionera energibranschen börjar lägga sig. Det är däremot oklart om det är en normal reaktion i en innovationsprocess likt Gartners hype-cykeln, eller om intresset för blockchain slocknat för gott. Den här uppsatsen har undersökt vilka värdeskapande egenskaper blockchain-teknologin besitter och om dessa egenskaper kan skapa värde i Sveriges framtida elsystem. För att kunna besvara denna fråga inleddes uppsatsen med en litteraturstudie för att förstå hur blockchain har tillämpats på tidigare projekt i energibranschen och vilka värdeskapande egenskaper tidigare studier har framhållit hos teknologin. Vidare har en intervjustudie med 28 deltagare genomförts med målet att förstå hur framtidens elsystem kommer se ut i Sverige och vilken åsikt som deltagarna hade gentemot blockchain. Litteraturstudien kunde konstatera att blockchain framför allt erbjuder dessa värdeskapande egenskaper; 1) transparent 2) decentraliserat 3) beständigt 4) spårbart och 5) individinteraktion. Vidare resulterade intervjustudien i en analys ur ett flernivå-perspektiv där det föreslås att Sveriges elsystem är i en konfigureringsfas som är drivet av ett nytt samhällstänk bestående av elektrifiering, digitalisering, utfasning av fossila bränslen och kärnkraftens framtid. Vidare framhåller denna studie att det svenska elsystemet står inför ett regimskifte från ett centraliserat system med stabil generation och konsumtionsbaserad produktion, till ett decentraliserat system med en ökad intermittent generation och en produktionsbaserad konsumtion. Detta regimskifte innebär däremot nya utmaningar där den gemensamma lösningen för dessa utmaningar är flexibilitet. Den här uppsatsen har funnit att om blockchain kommer vara värdeskapande för det framtida svenska elsystemet, är det som ett övergripande autentiseringslager på en potentiell flexibilitets marknad. Flexibiliteten kommer troligtvis vara decentraliserad och tillgodoses av många konsumenter och industrier. Marknaden kommer följaktligen behöva en autentiseringsprocess för att verifiera att leverantörer kan tillgodose en viss mängd flexibilitet vid ett specifikt tillfälle. Blockchains fem värdeskapande egenskaper kommer därför väl till pass då denna process behöver vara transparent, decentraliserad, spårbart och beständigt. Den här studien har däremot dragit slutsatsen att varken flexibilitets marknaden, affärsmodeller eller blockchain-teknologin är tillräckligt välutvecklade idag. Följaktligen är det för tidigt att uttala sig om blockchain är den bäst lämpade teknologin att använda sig av för autentisering, även om teknologins egenskaper indikerar en potential.

Cataloged from student-submitted PDF version of thesis.
Includes bibliographical references (pages 91-94).
In the current era of Internet of Things (IoT) devices, household solar panels, and increasingly aordable local energy storage, energy grid systems are facing a new set of challenges that they were not originally designed to support. Energy systems of the near future must be capable of supporting these new technologies, but new technology can also be leveraged to improve reliability and eciency overall. A major source of potential improvements comes from the increase of connected devices that are capable of dynamically adjusting their behavior, and offer new data that can be used for optimization and prediction. Energy predictions are used today at the bulk power system level to ensure demand is met through appropriate resource allocation. As energy systems become more responsive, prediction will be important at more granular system levels and timescales.
Enabled by the rise in available data, existing research has shown some machine learning models to be superior to traditional statistical models in predicting long-term aggregate usage. However, these models tend to be computationally expensive; if machine learning prediction models are to be used at short timescales and performed close to the end nodes, there is a need for more ecient models. Additionally, most machine learning models today do not take advantage of the known and studied properties of the underlying energy data. This thesis explores the circumstances under which machine learning can be used to make predictions more accurately than existing methods, and how machine learning and statistical methods can serve to complement each other (specically for short timescales at the household level).
We nd that basic machine learning models outperform other baseline and statistical models by using energy usage trends observed from statistical methods to better engineer the input features. For the increasingly distributed energy systems that these predictive models aim to support, the distributed nature of blockchain technology has been proposed as a good match for managing such systems. As an example of one possible distributed management implementation, this thesis presents a novel blockchain-enabled architecture that provides privacy for users, information security through improved household-level prediction, and takes into consideration the security vulnerabilities and computational constraints of the participants.

The emergence of blockchain technology and increasing penetration of distributed energy resources (DERs) have created a new opportunity for peer-to-peer (P2P) energy trading. However, challenges arise in such transactive markets to ensure individual rationality, incentive compatibility, budget balance, and economic efficiency during the trading process. This thesis creates an hour-ahead P2P energy trading network based on the Hyperledger Fabric blockchain and explores a comparative analysis of different auction mechanisms that form the basis of smart contracts. Considered auction mechanisms are discriminatory and uniform k-Double Auction with different k values. This thesis also investigates effects of four consumer and prosumer bidding strategies: random, preference factor, price-only game-theoretic approach, and supply-demand game-theoretic approach. A custom simulation framework that models the behavior of the transactive market is developed. Case studies of a 100-home microgrid at various photovoltaic (PV) penetration levels are presented using typical residential load and PV generation profiles in the metropolitan Washington, D.C. area. Results indicate that regardless of PV penetration levels and employed bidding strategies, discriminatory k-DA can outperform uniform k-DA. Despite so, discriminatory k-DA is more sensitive to market conditions than uniform k-DA. Additionally, results show that the price-only game-theoretic bidding strategy leads to near-ideal economic efficiencies regardless of auction mechanisms and PV penetration levels.

Blockchains, or distributed ledgers, are innovative information and communication technology (ICT) solutions that are emerging within various sectors and industries across the globe. This distributed ledger technology (DLT) is already widespread in certain sectors, mainly in the banking industry, often through corresponding banking, or syndicating and peer-to-peer (P2P) loans. Outstandingly, blockchain technology has the capability to enhance the transparency and authenticity of transactional processes throughout the whole supply chain. Another significant benefit that Blockchain technology provides, mainly coming from its transparent and decentralized nature, is the capability to decrease the information asymmetries among the collaborating partners. Through e.g. the digitalization of transactional mechanisms, decentralization of authority, Internet of Things (IoT) and asset management enabling as well as smart contracting, the improvement of the business's day-to-day operations is firmly forecasted. Importantly, the digitalization of the energy and other sectors will cause major alterations in current structures, and thus, it will require business model innovation. It is claimed that the decentralized nature of blockchain, mainly due to a reduction of middlemen could revolutionize current market structures and supply chains.Importantly, blockchain application is systematically growing across different industries, for instance in healthcare, voting systems, manufacturing, supply chain management, or luxury goods. It has also gained the attention of the energy industry, where digitalization is already visible in solutions such as smart meters and smart grids, electric e-mobility, vehicle-to-grid (V2G), energy cryptocurrencies and tokens, etc. This has resulted in the introduction of a novel concept of the Internet of Energy (IoE) in the academic literature. This literature analysis serves to determine the impact of blockchain on the imminent business models based on the renewable energy sector. The outcomes of this curiosity study provide numerous theoretical and managerial implications that can foster the widespread blockchain technology diffusion in global energy systems.

Positive Energy Blocks (PEBs) is a paradigm useful in the transition to a low carbon economy. This novel approach makes use the collective ownership of renewable energy generation and storage system to optimise their use. In addition to the networking of devices, PEBs also require a suite of managerial systems that can be used to integrate data with the network. One possible solution to this integration is by using Blockchain technology, which has the potential to resolve several issues in data management, security, and community integration. However, the use of Blockchains within PEBs has not been fully engineered or tested, and this paper presents the results of an exploration into possible solutions. The methods adopted in this research are descriptive and exploratory approaches in modelling a network of PEBs. This research points out how Blockchain technology would be used in the organisation process within a network of PEBs and would be useful for academics and professionals interested in delivering a new generation of buildings and services and in promoting collaborations.

Cryptocurrencies refer to a type of digital asset that uses distributed ledger, or blockchain technology to enable a secure transaction. Like other financial assets, they show signs of complex systems built from a large number of nonlinearly interacting constituents, which exhibits collective behavior and, due to an exchange of energy or information with the environment, can easily modify its internal structure and patterns of activity. We review the econophysics analysis methods and models adopted in or invented for financial time series and their subtle properties, which are applicable to time series in other disciplines. Quantitative measures of complexity have been proposed, classified, and adapted to the cryptocurrency market. Their behavior in the face of critical events and known cryptocurrency market crashes has been analyzed. It has been shown that most of these measures behave characteristically in the periods preceding the critical event. Therefore, it is possible to build indicators-precursors of crisis phenomena in the cryptocurrency market.
