Повний текст джерелаBlockchain 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.

Повний текст джерелаBlockchain 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.

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.

Повний текст джерелаIncreasing needs in energy, and earth pollution, coming from the use of polluting and non-renewable energy, make it indispensable the design of new energetic models, sustainable and reliable. Today, these new models are based on a massive integration of renewable generators in the grid. The renewable integration issues come from their stochastic features, depending on the weather conditions, most of the time. The coming of new information and communication technologies allows the integration of an information layer to the energy grid allowing it to be smarter and allow to have a glimpse of the possibility of a decentralised management of renewable energy. These energy being mainly decentralised, unlike imposing nuclear, coal and gas power plants, are produced directly at the customer's location. Consumers become, then, a prosumer able to answer to its own energetic needs,and maybe to act as a producer if it produces more energy than it consumes. But, the coming of a plethora of small actors, able to buy and sell energy, in real time, in a market containing the more powerful actors, traditional in the market, can be a source of volatility for energy prices. Considerable variations of the price can lead to detrimental situations by disturbing the grid. To face this problem, we developed a first mechanism for automatic negotiations, on three time scales, which decrees constraints on demand and on prices in order to guarantee their stability. This mechanism rely on representative entities (producers, prosumers and aggregators) to manage demand and supply without taking into account the impact on the grid of the negotiated contracts between these entities. The second mechanism, based on blockchain technology, allows bilateral decentralised negotiations and take into account the physical impacts on the grid of each energy exchange between prosumers, guaranteing then, the grid integrity. The proposed mechanism exempt itself from a management of the grid stability from a centralised third part

Повний текст джерелаThroughout the last few years, the electric market has undergone countless changes due to the continuous demand growth, the introduction of Information and Communication Technologies (ICT) on the network level, and the introduction of distributed generation sources, including household appliances that turned some consumers into a new category, prosumers. This way, the energy systems have become more decentralized through the development of the Internet of Things (IoT) which can allow for the creation of smart grids. Along with this transformation, there is also a change underway concerning consumer panorama as they become more central to the operations of the electric system. The introduction of all these technologies grants the prosumer the ability to participate more actively in the electric market, especially on the decentralization viewpoint, where each user contribute to the stability of the system operation. From this aspect, an interesting technology is the blockchain, which has revealed itself to have a huge potential in other areas, such as the financial sector. The research for the use of blockchain in the electric system has been due to its several promising characteristics. Namely, on account of its distributed and immutable nature which provides the potential to accelerate the transition of the electric market to a more digital and decentralized system. In this thesis, the blockchain capacities will be researched and adapted to develop of a scheme of energy transactions on the prosumer level. This will be done through the creation of a virtual market based on smart contracts, using the Solidity language in a remix environment, which will also allow consumers and energy producers to communicate between each other, exchanging tokens for electricity to satisfy the needs of all the evolved community. The use of blockchain will then make it possible for the creation of autonomous processes, allowing the system users to exchange energy, in a reliable and secure way, without the need of a third party.

Повний текст джерелаCombining rooftop solar with energy storage for off-grid residential operation is restrictively expensive. Historically, operating off-grid requires an 'isolated self-consumption' operating strategy where any excess generation is wasted and to ensure reliability you must install costly, polluting generators or a large amount of energy storage. With the advent of Blockchain technology residents can come together and establish transactive microgrids which have two possible operating strategies: Centralized Energy Sharing (CES) and Interconnected Energy Sharing (IES). The CES strategy proposes that all systems combine their photovoltaic (PV) generation and energy storage systems (ESS) to meet their loads. IES strategy establishes an energy trading system between stand-alone systems which allows buying energy when battery capacity is empty and selling energy when battery capacity is full. Transactive microgrids have been investigated analytically by several sources, none of which consider year-round off-grid operation. A simulation tool was developed through MATLAB for comparing the three operating strategies: isolated self-consumption, CES, and IES. This simulation tool could easily be incorporated into existing software such as HOMER. The effect of several variables on total cost was tested including interconnection type, initial charge, load variability, starting month, number of stand-alone systems, geographic location, and required reliability. It was found that the CES strategy improves initial cost by 7\% to 10\% compared to the baseline (isolated self-consumption) and IES cases in every simulation. The IES case consistently saved money compared to the baseline, just by a very small amount (less than 1\%). Initial charge was investigated for March, July, and November and was only found to have an effect in November. More research should be done to show the effect of initial charge for every month of the year. Load variability had inconsistent results between the two geographic locations studied, Indianapolis and San Antonio. This result would be improved with an improved load simulation which includes peak shifting. The number of systems did not have a demonstrable effect, giving the same cost whether there were 2 systems or 50 involved in the trading strategies. It may be that only one other system is necessary to receive the benefits from a transactive microgrid. Geographic locations studied (Indianapolis, Indiana; Phoenix, Arizona; Little Rock, Arkansas; and Erie, Pennsylvania) showed a large effect on the total cost with Phoenix being considerably cheaper than any other location and Erie having the highest cost. This result was expected due to each geographic location's load and solar radiation profiles. Required reliability showed a consistent and predictable effect with cost going down as the requirement relaxed and more hours of outage were allowed. In order to accomplish off-grid operation with favorable economics it is likely that a system will need to reduce its reliability requirement, adopt energy saving consumption habits, choose a favorable geographic location, and either establish a transactive microgrid or include secondary energy generation and/or storage.

Повний текст джерелаEsta dissertação teve como objetivo avaliar o impacto de inovadoras soluções de mercados inteligentes e tecnologia Blockchain em mercados locais de energia. Tendencias apontam para que o futuro das energias renovaveis passe por uma maior prevalencia de paineis fotovoltaicos domesticos. As sinergias entre as atuais dinamicas em mercados eletricos e o uso da Blockchain em mercados inteligentes parecem claras, podendo ser aproveitaveis para integrar novos perfis de consumo e conectar consumidores. Sendo um novo segmento, estratégias de mercado bem conseguidas serão essencias para ganhar posição, e a capacidade de angariar consumidores será um indicador crucial de sucesso. Para tal, os mercados têm que ser mais eficientes, algo que se tem revelado factual em casos de micro sistemas. Assim, criou-se o interesse de perceber como desenhar e implementar mercados localizados de energia que beneficiem desta tendencia de desintermediação. Para tal, um mercado interativo à base de leilões de eletricidade entre consumidores foi idealizado. Posteriormente, este foi simulado repetidamente, com diferentes dimensões e estruturas, a fim de perceber o seu impacto nos preços médios alcançados. Foi mostrado que tamanho e composição afetam os preços em magnitudes diferentes, sugerindo uma dimensão ideal de 25-40 participantes, com capacidades de autogeração superiores a 60%. Análises posteriors foram desenvolvidas de modo substantive, para avaliar o impacto de contadores eletricos inteligentes e integração da Blockchain neste tipo de mercado. Finalmente, conclusões foram reunidas e transformadas em recomendações para futuras implementações práticas.

Повний текст джерелаNo presente trabalho, é aplicado um paradigma de Internet Of Things (IOT) para agilizar e controlar o processo de carregamento de Veículos Elétricos (VE) em espaços partilhados de menores dimensões, como por exemplo condomínios residenciais, sem que seja necessária a intervenção (a título de prestação de serviços) de uma entidade externa, sendo todo o processo controlado pela gestão de condomínio. Uma aplicação móvel permite ao utilizador interagir com o sistema, permitindo a este autenticar-se no mesmo é condição necessária para que seja despoletado o processo de carregamento do VE. O sistema implementado com recurso a um microcontrolador encontrase ligado a um conjunto de sensores e um atuador permitindo medir a energia que esta ser consumida para carregamento do VE e simultaneamente, ligar e desligar o dispositivo de carregamento do veículo (através do controlo de um interruptor que entrega a energia entregue a este). O processo é controlado por uma unidade de gestão centralizada, que gera a distribuição de energia pelas estações de carregamento de VEs de acordo com as limitações do condomínio através do ligar e desligar destas e em simultâneo regista e processas as medições da energia consumida para consolidar as informações que constituem a transação de carregamento de VE e respetiva contraparte financeira associada à mesma. Adicionalmente, a unidade de gestão centralizada e a aplicação móvel, disponibilizam interfaces de utilizador mínimas para permitir funções como a consulta de transações, gestão e configuração da plataforma. Complementarmente, é apresentado um modelo conceptual permitindo escalar a solução proposta para espaços partilhados de maior dimensão, com recurso à utilização de tecnologias blockchain para gestão e registo das transações financeiras associadas à operação. Propondo uma abordagem, que poderá ser replicável em cenários mais amplos de utilização como por exemplo, a infraestrutura publica de carregamento de VE de uma cidade. O protótipo desenvolvido foi testado num espaço partilhado com três VE, usando uma infraestrutura de carregamento durante 3,5 meses.
