Texto completoEtt batterilager installerat separat eller tillsammans med en solelanläggning kan användas för mer än att öka egenanvändning av solel. Smart styrning med ett Energy Management System (EMS) möjliggör leverans av systemtjänster från batterilagret till elnätet. Hypotesen i denna studie innefattar att optimering av distributionen av ett energilagers kapacitet mellan kapning av effekttoppar och leverans av systemtjänsten frekvensreglering innebär en ökning av resursens värde. EMS som designats under detta projekt består av två delar; dels en prognosmodul som prognostiserar energianvändning för att ge rekommendationer för distribuering av kapacitet, dels en modul som i realtid styr batteriet baserat på prognosmodulens rekommendationer och uppmätt data. Prognosmodulen har testats i en fallstudie av Öckerö Ishall. Fallstudiens resultat visar att EMS som konstruerats reducerar nätavgiften med 9,5% genom att minska dagens högsta effekttopp med 21%. Resultatet visar även att frekvensreglering kunde levereras under tre timmar samma dag, vilket skulle generera ytterligare intäkter.

Texto completoShared situational awareness (SSA) is essential to success and safety in tactical environments, whether fighting wars or providing relief during disasters and humanitarian catastrophes. The increased availability of sensors in mobile devices offers groundbreaking opportunities for continuous context-aware applications that are capable of responding to the operating conditions of users and their environment. However, continuous context-aware applications involve high-energy consumption. A key challenge in tactical environments is to make the most effective use of scarce resources. There are numerous approaches for reducing energy consumption of continuous context-aware applications. This thesis examines two methods: Sensor Substitution and Triggering (SENST) and Acquisitional Context Engine (ACE). The goal of this thesis is to explore the capabilities and limitations of SENST and ACE for group context-awareness and provide a group energy-efficient sensor management strategy that enhances the dissemination of SSA in tactical environments.

Texto completoRisk management and corporate social responsibility took roles play how to manage global supply chain energy efficiency strategy and international logistics. All is based on facts-simulations, causes & impacts in transportation, production, and warehouse management”. In term of transportation in global supply chain shows for tracking performance systems hould be applied on appropriate standardized. Particularly for hazardous products. So that, the pollution level can be anticipated and calculated in exact level. The most important one is also the external level, so called leadership factor. This factor will reflect the corporate social responsibility performance.The type of production system which connected to global supply chain system is the most difficult one. Why do we have difficulties on this one? Because, some enterprises or countries for some extent could not make a better choice in term of scarcity for certain type of energy resources. For the warehouse section, the author found the result that electricity sector with real time data base has been giving realistic the way of energy efficiency of global supply chain.The energy efficiency in global supply chain is a perspective that efficiency energy in global level could be perform by any type of product, mainly on energy matter. By focusing on how to transport them, the way of production system, and how to build up warehouse system to keep source of energy become more efficient to serve end users

Texto completoIn contemporary world, hybrid electric vehicles (HEVs) have shown enormous potential in energy-saving and emission-reducing. By appropriate energy management strategy (EMS), an obvious improvement concerning energy efficiency could be achieved meanwhile self-sustainability is well reserved. Based on a specific HEV prototype Elba developed for Shell Eco-marathon (SEM), relevant research has been carried out by KTH Eco Cars research and development (R&D) teams during recent years. However, because of lack of a proper EMS, Elba meets a bottleneck on improving its energy efficiency and obtaining excellent grade in SEM. To solve this problem, this project is launched to develop a model-based optimization control hierarchy which can be implemented in Elba. Prior to this, some preliminary works have been done, including a set of simplified models of Elba and its powertrain components, and a dynamic programming (DP) based look-up table. Thus, the scope of this project is defined as establishing a complete energy management control hierarchy including three-layer controls. The developing process runs from bottom to top layer. The work starts from refining the original mathematical models according to the newly updated results of components testing and related technical datasheets. Then component-level controllers are developed. Model-based feedforward control together with feedback control for disturbance rejection is employed to replace previous PID control. In the middle layer control, the most significant part in this project, equivalent consumption minimization strategy (ECMS) is employed to realize a properly instantaneous torque split scheme on three propelling components. In this process, optimized fuel consumption among with real-time battery state of charge (SOC) are taken into account. To preserve Elba’s drivability, an improper working mode is identified and rejected to avoid frequent engine switching on/off as well as less efficient energy recuperation. In terms of the infeasibility of the existing DP based look-up table, a reasonable adjudgment function is introduced to complement its functionality. Thus, the modified look-up table is able to provide rational acceleration reference acting as top layer control. The whole work is finished in MATLAB/Simulink platform. The simulation results indicate that, compared with the previous control strategy, the new one significantly improves energy efficiency and better preserves battery SOC. Indeed, these decent results are on basis of some ideal assumption and simplified models. As an attempt on research and development of optimization control strategy, some precious experience and achievements have been, after all, obtained during the thesis work. All these will be verified by field tests and will promote Elba’s further upgrading in the future.

Texto completoENGLISH ABSTRACT: This research study explored energy efficiency and the possible implications for a South African company, the Pioneer Foods Group (Pioneer Foods). “What value could Pioneer Foods derive from an energy efficiency strategy?” is the research question posed in this study. The case study analysis revealed that Pioneer Foods recently listed on the Johannesburg Stock Exchange and therefore needed to implement an environmental management strategy as part of their carbon footprint reporting. Energy efficiency turned out to be one aspect that could have a significant impact on their carbon footprint. The most important barrier to energy efficiency identified at Pioneer Foods was found to be the lack of real-time electrical consumption information as this could result in a lack of ownership taken by mill management. Further barriers included the use of wrong information for benchmarking purposes as well as a possible misunderstanding of the different electricity tariffs shown on the electrical utility bill. Possible ways to overcome the barriers to energy efficiency at Pioneer Foods included installation of energy meters for real-time monitoring of the energy consumption, empowerment of people to ensure buy-in, as well as key performance indicators for mill managers linked to energy efficiency. It was suggested that the energy efficiency strategy be implemented in stages covering short-term, medium-term and long-term objectives. This way the implementation process would seem less intrusive to people and also give the energy efficiency team the opportunity to learn more and perhaps adjust the strategy throughout the implementation process. This research project should act as a starting point for Pioneer Foods to grow from being unconsciously incompetent to becoming consciously competent in the field of energy efficiency. The observations made throughout this study, should convince companies that energy efficiency should not just matter to high energy users. All companies should explore their own drivers for implementing energy efficiency and act on it.
AFRIKAANSE OPSOMMING: Hierdie navorsingstudie het die effektiewe gebruik van energie, en die moontlike implikasies vir ‘n Suid Afrikaanse maatskappy, die Pioneer Voedsel Groep (Pioneer Voedsel) ondersoek. “Watter waarde sou Pioneer Voedsel kon put uit ‘n energie-effektiwiteit-strategie?” is die navorsingsvraag wat in hierdie studie gestel is. Uit die analise blyk dat Pioneer Voedsel onlangs op die Johannesburgse Effektebeurs genoteer is. Daar word dus van hulle verwag om ‘n omgewingsbestuur-strategie in plek te stel as deel van hul koolstofvoetspoor-verslaggewing. Dit blyk dat energie-effektiwiteit een aspek is wat ‘n groot impak op hulle koolstofvoetspoor kan hê. Die grootste struikelblok tot energie-effektiwiteit by Pioneer Voedsel geïdentifiseer, was die tekort aan intydse elektriese verbruiksinligting. Dit kan veroorsaak dat die bestuur nie eienaarskap neem van energie-effektiwiteit nie. Verdere struikelblokke sluit in die gebruik van foutiewe inligting vir metingsdoeleindes asook ‘n moontlike gebrek aan begrip van die verskillende elektrisiteitstariewe uiteengesit op die elektrisiteitsrekening. Moontlike maniere om die struikelblokke by Pioneer Voedsel te oorkom sluit in die installasie van energiemeters vir intydse monitering van energieverbruik, bemagtiging van mense om inkoop te verseker, en sleutelprestasie-aanwysers vir bestuurders gekoppel aan energie-effektiwiteit. Dit word voorgestel dat die energie-effektiwiteit-strategie in fases geïmplementeer word om sodoende kort-, medium- en langtermyn-mikpunte te bereik. Sodoende sal die implementering van die proses minder indringend vir personeel wees. Dit gee ook die energie-effektiwiteit-span die kans om meer te leer asook die strategie aan te pas soos nodig tydens die implementeringsproses. Hierde navorsingsprojek moet dien as die vertrekpunt vir Pioneer Voedsel om te groei van onwetend onbekwaam tot wetend bekwaam in die veld van energie-effektiwiteit. Verder behoort dit maatskappye te oortuig dat energie-effektiwiteit nie net ‘n verskil maak vir hoë energie verbruikers nie, maar dat alle maatskappye hulle eie drywers vir die implementering van energie-effektiwiteit behoort te identifiseer en daarvolgens aksiestappe te neem.

Texto completoTraditionally organizations have reported largely on financial information. The Global Reporting Initiative and the King III Code of Corporate Governance have become important guidelines in assisting organizations on how to report and consequently integrated reporting is quickly gaining popularity. As the potential effects of climate change and other environmental and social impacts of businesses become more apparent, stakeholders are placing pressure on these organizations to be more transparent in how they are dealing with these impacts. Strategy cannot be separated from sustainability (SAICA, 2009: 7); therefore there is increasing pressure on organizations to disclose their strategies. Not all companies disclose information relating to strategy and sustainability to the same extent. There are a range of factors that influence strategy disclosure. This study updates the 2010 study (Meyer, 2011) evaluating the extent of strategy disclosure in the energy and natural resources sector of five companies (BP, Eskom, Mondi, Sappi and Sasol) using a three-point evaluation scale. In addition the following analyses were done: A benchmarking exercise comparing the strategy disclosure and sustainability reporting of the five companies analysed against two industry leaders (Repsol and Enagas). Development of the drivers of strategy disclosure from the literature which were compared to the results from the three-point evaluation scale. The analysis was repeated using a six-point evaluation scale, as this more clearly determined the extent of strategy disclosure, which was then compared to the drivers of strategy disclosure. The results, obtained from the six-point evaluation scale, supported the drivers of strategy disclosure and concluded that product type, the competitive environment and risk are some of the main determinants of strategy disclosure in this study based on the companies evaluated. It was also concluded that, based on the three-point and the six-point evaluation scale, the average level of disclosure for the energy and natural resources sector is good, and had improved from 2010. Furthermore, it was also observed that strategy is not disclosed to the same extent as sustainability information. Baseline One had more of a focus on sustainability information, whereas Baselines Two and Three focussed more on strategy. The level of disclosure in Baseline One was more than that of Baselines Two and Three.

Texto completoThe global energy industry is actively moving toward renewable energy sources in order to meet the ever-increasing demand for energy in a sustainable manner. The South African government, however, has only recently begun creating an environment which is truly conducive to investment into the renewable energy industry. Metso, a Finnish multi-national corporation, has a strong global position in the field of biomass-based power generation for heat, power or combined heat and power applications. The corporation has developed a modular biomass-based power generation solution for power generation in the 3MW to 10MW range, which is highly automated and can essentially operate without the need for extensive human intervention and is known as the Metso Bio-energy Solution. Considering the current state of the South African energy environment, Metso management requested the researcher to investigate the opportunities that exist in the South African market for Metso’s Bio-energy Solution, and to propose a market entry strategy which Metso should follow in order to enter the South African market. In the findings, the researcher observed that South Africa has a clear potential for the development of a bio-energy industry for power generation, although the limited availability of biomass in certain regions and the various harvesting methods in industries such as the forestry and sugar industries do restrict the access to this resource. The municipal solid waste industry appears to be an area of interest as well, although very little information exists regarding the volumes of waste available and sorting practices, which may be required in order to access these resources. Interviews were held with experts in the field of energy, renewable energy and energy policy in order to obtain opinions on the market potential for Metso’s Bio-energy Solution. The general perception of all interviewees was that the technology has its place within the South African energy mix. The interviewees, however, did confirm that there currently appears to be a major focus on wind and solar energy in the country, although biomass technology may well be a better solution due to its baseload capabilities. It was found that the local policy environment, the lack of government initiative on renewable energy licensing and unclear tariff structures have all inhibited the proliferation of the renewable energy industry. In many cases, frustration with power outages and policy delays has caused companies to invest in biomass co-firing facilities for their own consumption. The factors for success for biomass-based technologies in the South African market would appear to be directly linked to job creation potential, access to reliable and sustainable biomass resources and access to investment capital, from both private equity and the state. It is the recommendation of the researcher that Metso enters into a joint venture with a large international environmental finance company, which would base their business model on the technology provided by Metso, whilst securing the political and financial support for projects of this nature in the country.

Texto completoAs a University that has been low rated amongst government agencies 2009, today KTH has a vision to become one of Europe’s leading universities in sustainable development. The aim with this paper is to investigate the energy consumption at KTH from a systems perspective. Another purpose is that the result could be used as a guideline for future work. The paper involves mapping of the energy consumption in the schools of KTH and a description of the current state regarding the energy work. Further, an interview survey has been performed in order to achieve a better understanding of how Akademiska Hus and KTH relates to the energy topic. The mapping shows that all schools shows a reduction in their energy consumptions, where ABE by the year 2015 has an energy consumption of 3988 MWh which is a decrease by 30 % compared to 2011 (5690 MWh). The lowest reduction is shown by ICT which counts to 8 %. The total energy consumption coming from facilities at KTH is counted to approx. 188 GWh. The result of this paper shows that the environmental work of KTH have not been on a satisfying level and that the current rental model between KTH and Akademiska Hus does not encourage progress in the energy topic at KTH. Further, it is proven that Akademiska Hus and KTH have different levels of ambition in the energy matter, and that the energy reporting tool that is provided to KTH has clear improvement potentials, where a distinction between property – and operation electric is one of them. This would allow clearer follow-ups of the energy goals in KTH, which is not the case today. A summary of improvement suggestions from the conclusions of the study are: Create a counterpart at KTH to the energy strategist at AH that could facilitate the communication between the parties and highlight the energy issues at KTH. Start a discussion concerning the rental model and improve it, to create incentives for energy savings mainly at the KTH side. Develop and introduced an improved energy reporting tool.

Deregulation shaping the Electricity industry across the world is a systems challenge cutting across interdisciplinary fields of technology, economics, public policy, environment and sociology. Decision makers that shape tomorrow's policy and investors that invest in financial and technological developments in this industry need to rely on multiple decision models to make informed decisions. This thesis serves to provide one such decision model among many that could be used to understand the key dynamics shaping a highly complex industry. We employ "top-down" and "bottom-up" approaches to build system dynamics model in an attempt to distinguish between adoption and diffusion phenomenon, as a result benefiting from hybrid modeling techniques that combine structures from both models. The models are evaluated with wide range of scenarios to arrive at policy guidance and business model recommendations. The dynamic hypothesis arising from our system dynamics model points to declining marginal profits in a saturating market coupled with proliferation of competitors, over-estimation of demand and diminishing margins for Curtailment Service Providers (CSPs) in the long run. We propose recommendations to surmount these challenges. To tap the smaller commercial and residential markets, CSPs must extend its reach by partnering with composite channel partners, who in the long run could also play a vital role in demand generation. In the face of commoditization and disruptive innovations, CSPs would not be able to sustain their margins just by aggregating demand response (DR) capacity, they would need to reinvent themselves to become energy management firms providing integrated, automated turnkey energy services including energy efficiency services, risk management, planning, sourcing along with providing DR services. Taking a systems approach in evaluating demand-side technology, we further investigate environmental implications of DR by characterizing the carbon savings from DR. Our analyses revealed that the carbon savings from DR triggered load curtailment when calculated using system wide carbon intensities differ substantially from those calculated with locational carbon intensities. Locational carbon intensity captures the location and time-specific dynamics of electricity demand. We, therefore, recommend it is a better metric for evaluating total carbon savings from load curtailment, which could be used to devise carbon abatement policies and structure the electricity market design rules. Furthermore, adding a carbon price to the marginal cost equation could change the dispatch order of plants and thus align carbon abatement policies with load reduction schemes.

A hybrid electric vehicle with an engine on the front axle and an electric motor on the rear axle is analyzed. A control strategy is developed based on a set of rules with different modes depending on the vehicle speed and accelerator pedal position, switching between using only the electric motor, only the engine, and a combination of both. The control strategy increases fuel economy while maintaining the charge level of the hybrid battery pack and providing a smooth and enjoyable driving experience.

Texto completoThis PhD thesis proposes Energy Management Strategies conceived for a hybrid electrical urban bus. The hybrid control system should create an efficient strategy of coordinating the flow of energy between the heat engine, battery, electrical and hydraulic motors. Firstly, a Deterministic Dynamic Programming (DDP) based approach has been proposed: simultaneous speed and powersplit optimization algorithm for a given trip (constrained by the traveled distance and time limit). This algorithm turned out to be highly time consuming so it cannot be used in real-time. To overcome this drawback, an Optimal Profiles Database based on DP (OPD-DP) has been constructed for real-time application. Afterwards, a Stochastic Dynamic Programming (SDP) technique is used to simultaneously generate an optimal speed profile and related powersplit strategy. This approach takes into account a stochastic nature of the driving behavior and urban conditions. The formulated energy optimization problem, being intrinsically multi-objective problem, has been transformed into several single-objective ones with constraints using an ε-constraint method to determine a set of optimal solutions (the Pareto Front).In urban environment, due to traffic conditions, traffic lights, a bus encounters frequent Stop&Go situations. This results in increased energy consumption during the starts. In this sense, a relevant Eco Adaptive Cruise Control with Stop&Go (eACCwSG) strategy brings the undeniable benefit. The algorithm smooths speed profile during acceleration and braking phases. One more important feature of this algorithm is the safety aspect, as eACCwSG permits to maintain a safety distance in order to avoid collision and apply a smooth braking. As it was mentioned before, smooth braking ensures passengers comfort

Texto completoInitiatives to decrease emissions from the transport sector are increasing worldwide by seeking alternative technologies to replace oil-based mobility. Battery Electric Buses (BEB) present a promising solution thanks to their high energy efficiency, low greenhouse gas emissions and the absence of local pollutant emissions. However, this technology still faces many challenges, especially its high total cost of ownership (TCO) and other operational factors such as the limited bus driving range, the high energy refueling time, and the required charging technologies and strategies. In this context, this thesis presents a systematic methodology that aims at developing solutions to help overcoming these challenges by providing optimal battery sizing and charging strategy for BEB. First, a comprehensive multi-physical bus energy model is developed to evaluate its energy needs considering all the energy systems encountered within. The energy consumption of the bus is then evaluated at a variety of operating conditions. Then, a techno-economic model of an entire bus line is developed in order to assess the impact of different battery sizing and charging strategies on the costs and operation of BEB. A TCO model is introduced considering the BEB unit costs, battery purchase and replacement costs, energy and power costs, infrastructure, and maintenance costs. A case study in Paris city is presented and the analysis reveals the resulting tradeoff between the TCO and BEB schedule disruptions and delays as function of different battery sizes and charging strategies. A methodology to minimize the TCO of BEB deployment is presented providing the optimal battery sizing and charging strategy for BEB, while respecting the BEB operation constraints. The methodology is a 2-step optimization algorithm that utilizes both Dynamic programming and Genetic Algorithm optimization routines. The results show that the proposed methodology could reduce the BEB TCO between 15-25% compared to the currently adopted approaches to deploy BEB

Texto completoSCADA (Supervisory Control and Data Acquisition) systems have been widely used during the last decades delivering excellent results for the power network operation and management. However, some current customer requirements are for SCADA systems to integrate external components in order to perform advanced power network studies and develop both existing and new business processes. This novel viewpoint will make these systems evolve from a monolithic infrastructure towards a loosely coupled and flexible architecture. Hence, new needs have arisen with the aim of improving the system interoperability, reducing the complexity and enhancing the maintainability. This master´s thesis project presents an Interoperability Prediction Framework (IPF), that supports the architecture design process during the early stages of product development. In addition, this work has also investigated some alternative architectures, which have been modelled and verified using the previously mentioned framework. A first conceptual architecture has been designed to improve the internal system interoperability, reducing the coupling between the basic SCADA and the Energy Management System (EMS). Later, a second architecture that allows the integration of external components has been introduced to promote the external interoperability. Results show that the proposed architectures are correct (according to the IPF) and the interoperability of the system is improved. Furthermore, initial conclusions suggest that the final proposed solution would be less complex than the current architecture in the long term, although a large effort and substantial changes would be needed to upgrade the system architecture.

Texto completoA dia d’avui l’energia és un bé completament necessari arreu del món. Degut als avantatges que presenta en el transport i a les necessitats de les llars i la indústria, l’energia és transformada en energia elèctrica. Tenint en compte la total expansió i domini de l’electricitat, iniciatives com Horitzó 2020, tenen per objectiu un futur més sostenible: reduint les emissions de carboni i el consum i incrementant l’ús de renovables. Partint dels defectes de la xarxa elèctrica clàssica, com són gran distància al punt de consum, poca flexibilitat, baixa sostenibilitat, baixa qualitat de l’energia, dificultats per a emmagatzemar energia, etc. apareixen les Smart Grid (SG), una evolució natural de la xarxa clàssica. Un dels principals elements que permetrà a les SG millorar les xarxes clàssiques és l’Energy Management System (EMS). Així doncs, per a que l’EMS pugui dur a terme la gestió dels diversos elements, una de les necessitats bàsiques dels EMS serà un sistema de predicció, o sigui, saber per endavant quin consum hi haurà en un entorn determinat. A més, les empreses subministradores d’electricitat també requeriran de prediccions per a gestionar la generació, el manteniment i fins i tot les inversions a llarg termini. Així doncs ens calen sistemes de predicció del consum elèctric que, partint de les dades disponibles, ens subministrin el consum que hi haurà d’aquí a unes hores, uns dies o uns mesos, de la manera més aproximada possible. És dins d’aquest camp on s’ubica la recerca que presentem. Degut a la proliferació de xarxes de sensors i computadors més potents, s’han pogut desenvolupar sistemes de predicció més precisos. A tall de resum, en el primer treball, i tenint en compte que s’havia de conèixer en profunditat l’estat de la qüestió en relació a la predicció del consum elèctric, es va fer una anàlisi completa de l’estat de l’art. Un cop fet això, i partint del coneixement adquirit, en el segon treball es va dur a terme la instal•lació de les xarxes de sensors, la recollida de dades de consum i el modelatge amb models lineals d’auto-regressió (AR). En el tercer treball, un cop fets els models es va anar un pas més enllà recollint dades d’ocupació, de meteorologia i ambient interior, provant diferents models paradigmàtics com Multiple Linear Regression (MLR), Artificial Neural Network (ANN) i Support Vector Regression (SVR) i establint quines dades exògenes milloren la predicció dels models. Arribat a aquest punt, i havent corroborat que l’ús de dades d’ocupació millora la predicció, es van generar tècniques per tal de disposar de les dades d’ocupació per endavant, o sigui a hores vista. D’aquesta manera es van dissenyar diferents atributs d’ocupació artificials, permetent-nos fer prediccions horàries de consum a llarg termini. Aquests conceptes s’expliquen en profunditat al quart treball.

Texto completoFuel cell hybrid propulsion system is gaining momentum in today's automotive market and offers a sustainable solution for the world climate change in the transport sector. However, the durability and reliability of the power sources used in the hybrid system are the inevitable obstacles for its massive commercialization. To optimize and maximize the lifespan of the hybrid system, a prognostics and health management (PHM) approach is deployed to manage and mitigate the power source degradation behaviour and applied to a fuel cell hybrid electric vehicle.In this context, two main contributions are made. The first stage is to deploy a prognostics method that can be used in the hybrid system. Particle filtering, as a commonly used state estimation method, is adapted for prognostics purpose in this thesis. It is used to handle the imprecise and uncertain degradation data and estimate the remaining useful life. The method is validated by historical fuel cell and battery datasets and the results are evaluated by the designed prognostics metrics.Subsequently, a second stage on the health management aspect of PHM is proposed. As the split of demanded power in a hybrid system is managed by an energy management strategy (EMS), the orientation of this stage is to develop a health-conscious EMS in the context of PHM. A great quantity of researches on prognostics with finished experimental data have been found in the literature, while how to use the prognostics results to make corrective control actions is rarely discussed. To help against this vacancy in hybrid system applications, a prognostics-enabled decision-making process is designed. The performance is evaluated by quantifying the degradation and the lifetime of the system in a simulated environment and a discussion on prognostics occurrence is launched for further investigations on maintenance
