The integration of renewable energy resources into the electricity grid presents an important challenge. This book provides a review and analysis of the technical and policy options available for managing variable energy resources such as wind and solar power. As well as being of value to government and industry policy-makers and planners, the volume also provides a single source for scientists and engineers of the technical knowledge gained during the 4-year RenewElec (renewable electricity) project at Carnegie Mellon University, the University of Vermont, Vermont Law School, and the Van Ness Feldman environmental law firm. The first part of the book discusses the options for large scale integration of variable electric power generation, including issues of predictability, variability, and efficiency. The second part presents the scientific findings of the project. In the final part, the authors undertake a critical review of major quantitative regional and national wind integration studies in the United States. Based on comparisons among these studies, they suggest areas where improvements in methods are warranted in future studies, areas where additional research is needed to facilitate future improvements in wind integration studies and how the research can be put into practice.

Stability of the electricity industry is crucial for economic growth of all nations. Sustainable economic growth cannot be accomplished without secured energy supply. The book underlines how management of the electricity industry should be conducted and the efficient form of electricity market structure. The book also studies the electricity industry in Korea which has been a strongly supportive and vital factor in the economic development of Korea for the last few decades. The book focuses on the three market players of the electricity market and they are the suppliers, consumers and the government-related organizations. It includes detailed information on generation and finances at the generator level and analyzes the efficiency differences among generators, plants and business units by using different performance measurement methods. It identifies and analyzes different production factors' effectiveness and relationships in generation. The comprehensive analysis helps to provide explanations in the differences in the performance of the studied units. The book also discusses the implications of the findings for future resource allocation and how we can further enhance the efficiency of the industry. The book will appeal to those interested in energy and energy policies, as well as researchers and practitioners in the economic development and electricity and utilities industry.

In 1896 a young Italian arrived in England with some mysterious scientific apparatus as part of his personal luggage. The Customs officials, who had seen nothing like it before, examined it so thoroughly that the delicate apparatus was completely wrecked. This was the inauspicious beginning of a venture that was destined to remould the pattern of twentieth century living. The book begins with a brief resume of early scientific discoveries up to 1896 and goes on to record the fortunes of the Marconi company. In the course of the book the author covers in detail the story of radio communications from the first wireless signals across the Atlantic to the transmission of colour television programmes via satellite. The narrative includes the development of electronic devices during two world wars and the histories of such specialist fields as sound broadcasting, television, aviation electronics and radar. The technical stories are told against the backcloth of a Company's successes and setbacks and commercial "wars". A lively reading, which can be readily understood by the lay reader. For the technical man, circuit diagrams of early apparatus give added interest. The text is generously illustrated with photographs from the Marconi archives.

If you're lucky enough to be employed today in the United States, there's about a one-in-ten chance that you're in a labor union. And even if you re part of that unionized 10 percent, chances are your union doesn't carry much economic or political clout. But this was not always the case, as historian and activist James Young shows in this vibrant story of the United Electrical Workers Union. The UE, built by hundreds of rank-and-file worker-activists in the quintessentially industrial town of Erie, Pennsylvania, was able to transform the conditions of the working class largely because it went beyond the standard call for living wages to demand quantum leaps in worker control over workplaces, community institutions, and the policies of the federal government itself. James Young's book is a richly empowering history told from below, showing that the collective efforts of the many can challenge the supremacy of the few. Erie's two UE locals confronted a daunting array of obstacles: the corporate superpower General Electric; ferocious red baiting; and later, the debilitating impact of globalization. Yet, by working through and across ethnic, gender, and racial divides, communities of people built a viable working-class base powered by real democracy. While the union's victories could not be sustained completely, the UE is still alive and fighting in Erie. This book is an exuberant and eloquent testament to this fight, and a reminder to every worker employed or unemployed; in a union or out that an injury to one is an injury to all."

Innovation is key to achieving a sustainable electricity system. New technologies and organizational changes can bring about more sustainable, climate-friendly electricity structures. Yet the dynamics of innovation are complex, and difficult to shape. This book, written by experts in the field, sets out to explore the dynamics, the drivers and the setting of innovation processes. Case studies on micro cogeneration, carbon capture and storage, consumer feedback, network regulation and emissions trading provide insights into innovation dynamics in the electricity system and are analyzed to derive strategic implications for innovation policies. A special focus is placed on drivers and barriers of change, and their consequences for shaping the innovation process. This book is an indispensable source of information for researchers and decision makers in energy and climate change as well as for lecturers and students interested in the principles and ramifications of electricity innovation dynamics.

The Chinese electricity sector is the largest in the world, covering well over 20% of the world's electricity supply. While many other countries liberalized their electricity systems in the 1990s, thereby creating competitive wholesale and retail electricity markets, China's move towards liberalization has advanced at a slower pace - until now. Following the China State Council's publication of the No. 9 document on 'Deepening Reform of the Power Sector', this book reflects on the ambitious new round of reforms aimed at introducing competitive wholesale electricity markets and incentive regulation for its power grids. Written in collaboration with Hao Chen, Lewis Dale and Chung-Han Yang, this book provides lessons for China's reforms from international experience, combining a detailed review of reforms from around the world with specific application to China and focuses on how the industrial price of electricity is determined in a liberalized power system.

It also presents key advanced features of modeling and automation of calculations using PowerFactory, such as the use of domain-specific (DSL) and DIgSILENT Programming (DPL) languages, and utilizes a variety of methodologies including theoretical explanations, practical examples and guidelines. Providing a concise compilation of significant outcomes by experienced users and developers of this program, it is a valuable resource for postgraduate students and engineers working in power-system operation and planning.

Electricity markets are structurally different to other commodities, and the real-time dynamic balancing of the electricity network involves many external factors. Because of this, it is not a simple matter to transfer conventional models of financial time series analysis to wholesale electricity prices.

The rationale for this compilation of chapters from international authors is, therefore, to provide econometric analysis of wholesale power markets around the world, to give greater understanding of their particular characteristics, and to assess the applicability of various methods of price modelling.

Researchers and professionals in this sector will find the book an invaluable guide to the most important state-of-the-art modelling techniques which are converging to define the special approaches necessary for unravelling and forecasting the behaviour of electricity prices. It is a high-quality synthesis of the work of financial engineering, industrial economics and power systems analysis, as they relate to the behaviour of competitive electricity markets.

This book fills a gap in the existing literature by dealing with several issues linked to long-term contracts and the efficiency of electricity markets. These include the impact of long-term contracts and vertical integration on effective competition, generation investment in risky markets, and the challenges for competition policy principles. On the one hand, long-term contracts may contribute to lasting generation capability by allowing for a more efficient allocation of risk. On the other hand, they can create conditions for imperfect competition and thus impair short-term efficiency. The contributors - prominent academics and policy experts with inter-disciplinary perspectives - develop fresh theoretical and practical insights on this important concern for current electricity markets. This highly accessible book will strongly appeal to both academic and professional audiences including scholars of industrial, organizational and public sector economics, and competition and antitrust law. It will also be of value to regulatory and antitrust authorities, governmental policymakers, and consultants in electricity law and economics. Contributors: J. Boucher, G. Brunekreeft, D.

Ina Peters analyzes how collective identities and collective action frames have contributed to the persistence and eventual fragmentation of the collective action against the Belo Monte Dam. Reconstructing the rationale of the conflict, Ina Peters addresses theoretical research gaps regarding the dynamics - particularly cohesion and fragmentation - in social movements. The study considers the influence of the regional context and the applicability of Western theories in non-Western case studies. It is based on primary data that was collected through semistructured interviews and analyzed in detail by means of a combined top-down and bottom-up procedure based on the grounded theory methodology.

This book addresses the vector control of three-phase AC machines, in particular induction motors with squirrel-cage rotors (IM), permanent magnet synchronous motors (PMSM) and doubly-fed induction machines (DFIM), from a practical design and development perspective. The main focus is on the application of IM and PMSM in electrical drive systems, where field-orientated control has been successfully established in practice. It also discusses the use of grid-voltage oriented control of DFIMs in wind power plants. This second, enlarged edition includes new insights into flatness-based nonlinear control of IM, PMSM and DFIM. The book is useful for practitioners as well as development engineers and designers in the area of electrical drives and wind-power technology. It is a valuable resource for researchers and students.

Shabnam Mirsaeedi-Farahani analyzes Iran's interests in diversifying its energy sector, specifically electricity generation and consumption, between 1990 and 2011. She examines the policy discussions in the Iranian Parliament as well as policy development and implementation with respect to the electricity sector. One of the geopolitically crucial areas for both Iran's domestic development as well as its international influence has been its energy sector. The author assesses international policy pressures and domestic interests to evaluate the interplay of interests, actors, and strategies. While increasing domestic generation capacity, Iran has been able to further its regional interests and influences as well as to build a backbone for its industrialization endeavors.

Ever since Schumpeter's groundbreaking work there has been a plethora of new research seeking to extend the direction and dynamics of innovation. Using a rich account of detailed interviews, this book offers new evidence on how latecomers have successfully caught up and leapfrogged incumbent firms. Catching Up and Leapfrogging: the new latecomers in the integrated circuits industry explores how technological transitions affect latecomer catch-up strategies, and vice versa, in a high technology industry. It looks to the East Asian latecomers who, towards the end of the twentieth century, pioneered a new pathway through organizational change by specializing in the key production stages of integrated circuits and pushing technologies further. This volume assesses how latecomer resource acquisition strategies have varied alongside structural industry changes and evaluates the mechanisms through which firms started life as technology followers and rose to become technology leaders. Xiao-Shan Yap and Rajah Rasiah present a unique story about how firm strategies evolve from the catching up phase to the leapfrogging phase, captured from the accounts of managers on the ground. It is the first time firm-level strategies have been systematically analysed to describe twenty-first century strategic management in the integrated circuits industry in particular, and the high tech industry in general. The evidence and analysis in this book offers insights for chief executive officers, policy-makers and researchers to revisit existing approaches to the theory of catching up and leapfrogging.

The meteoric rise of the photovoltaic (PV) industry is an incredible story. In 2013, Google s investments in PV systems totaled about half a billion dollars and Warren Buffet, one of the famous investors, invested $2.5 billion in the world s largest PV system in California. These gigantic investments by major financial players were made only 40 years after the first two terrestrial PV companies, Solarex and Solar Power Corporation, were formed in the USA. Back in 1973, the two companies employed 20 people and produced only 500 watts of PV power. Now, just 40 years later, over a million people work in the PV industry. The worldwide capacity of operating PV electric generators equals the capacity of about 25 nuclear power plants. The PV industry is growing at an annual rate of 30 percent, equivalent to about five new nuclear power plants per year. Today, solar electricity is a significant supplier of electricity needs, to the extent that PV is forcing the restructuring of 100-year-old electric power utilities. This book describes how this happened and what lies ahead for PV power generation."

After the first power plant in history was commissioned for commercial operation by Thomas Edison on Pearl Street in New York in 1882, electricity was sold as a consumer product at market prices. After a period of rapid development, electricity had become such a fundamental product that regulation was believed to be necessary. Since then, the power industry had been considered a natural monopoly and undergone periods of tight regulation. Deregulation started in the early 1980s and as a result, most developed countries run their power industries using a market approach. With the theories and rules of electricity markets developing rapidly, it is often difficult for beginners to start learning and difficult for those in the field to keep up. Bringing together information previously scattered among various journals and scholarly articles, Electricity Markets and Power System Economics provides a comprehensive overview of the current state of development in the electricity market. It introduces the fundamental principles of power system operation so that even those with a basic understanding can benefit from the book. The book includes a series of consistent mathematical models of market operation of power systems, and original cases with solutions. Systematically describing the basic building blocks of electricity market theory, the book provides a guide to underlying theory and mainstream market rules.

Margot P. C. Weijnen, Zofia Lukszo and Geert Deconinck Abstract The infrastructures for electric power and information and telecommunication services are critical enablers for all economic activity. Both of these infrastructure systems evolved over time as networks-of-networks in an institutionally fr- mented landscape. In understanding and steering the emergent behaviour of these infrastructure systems both their physical network complexity and their social n- work complexity pose a formidable challenge. On top of the socio-technical c- plexity of the electricity infrastructure and the information and telecommunication infrastructure as such, the two infrastructure systems show unprecedented mutual interdependency. Unravelling this multi-level interdependency and identifying strategies to curb the new risks and vulnerabilities it implies for the reliability of electric power services is the goal of this book. It clearly shows that technical so- tions alone will not suffice to ensure the future reliability and security of electricity infrastructure operations. Keywords Cybersecurity * infrastructure vulnerability * infrastructure depend- cies * power systems 1. 1 Infrastructures Are Critical Infrastructures are the backbone of the economy and society. Especially the network bound infrastructures operated by public utilities and network industries provide essential services that are enabling for almost every economic and social activity. M. P. C.

Two general questions stood at the beginning of this PhD-thesis, namely: * What are the mechanisms which lead to the emergence and establishment of new technologies? * How can this process of technological change be influenced politically? In this sense, conceptual and theoretical interests were the early driving forces of the research work. This is also reflected in the considerable attention paid to the nature of technological change and political control. The result is an holistic per spective which builds on inputs from different disciplines and aims at dynamic interpretation. This, however, created a severe methodological problem: How could such a comprehensive perspective be used constructively? To develop this link between theory and forward-looking, policy-oriented analysis, and to devise a methodology which showed explicitly how this approach could be used in a con structive way were in fact the major challenges of this research project. The appli cation to the example of combined heat and power generation, and the comparison of the developments in the UK and in Germany serve the purpose to demonstrate how this approach and methodology can be implemented in practice. These as pects were also of particular interest to the Institute for Prospective Technological Studies (IPTS), one ofthe institutes of the European Commission's Joint Research Centre, where most of the research work reported in this PhD-thesis was carried out.

1.1 Economic issues to be analyzed This research examines two elements of the Swiss market for electricity: the residential electricity demand by time-of-use and the cost structure of municipal electricity distribution utilities. The empirical results of demand and cost elasticities allow the investigation of interesting economic and policy issues such as the desirability of a widespread introduction of time-of-use pricing for residential customers, the desirability of side-by-side competition in the distribution of electricity and, more generally, the economic effects of a reduction of the load factor and of mergers between electric distribution utilities on costs. Desirability of time-of-use pricing In the last decade there has been an intensifying debate in Switzerland about efficacy of electricity rate reforms in order to improve the efficiency of electricity use. This debate was initiated by two main events. First, there was an important growth of electricity consumption. Second, the Chernobyl accident in 1986 aroused widespread public concern about the problems associated with nuclear power and waste disposal. As a result, in 1991 the Swiss voted, in a referendum, a lO-year moratorium on the 2 construction of new nuclear power plants. Moreover, plans to expand production of hydroelectric power (construction of new dams or expanding existing ones) have been stiffly opposed by environmental groups. These developments have consistently curtailed potential expansion of domestic electricity supply. As a result, Switzerland during the winter has to import electricity from foreign countries.

After improving steadily for decades, the technology that brought unequalled productivity growth to the American electric utility industry appeared to stall in the late 1960s, making it impossible to mitigate the difficult economic and regulatory assaults of the 1970s. Unfortunately, most managers did not recognize the severity of the technological problems they faced and chose to focus instead on issues that appeared more manageable. Partly as a result of this lack of attention to technological issues, the industry found itself challenged by the prospects of deregulation and restructuring in the 1980s. This book focuses on the role of technological stagnation in the decline of the industry and argues that a long and successful history of managing a conventional technology set the stage for the industry's deterioration.

Power system operation is one of the important issues in the power industry. The book aims to provide readers with the methods and algorithms to save the total cost in electricity generation and transmission. It begins with traditional power systems and builds into the fundamentals of power system operation, economic dispatch (ED), optimal power flow (OPF), and unit commitment (UC). The book covers electricity pricing mechanisms, such as nodal pricing and zonal pricing, based on Security-Constrained ED (SCED) or SCUC. The operation of energy market and ancillary service market are also explored. "It covers a wide range of interesting topics, which could be very useful for understanding the main phenomena ruling power systems economy (such as Optimal Power Flow analysis and unit Commitments). It addresses topics widely treated in the literature, hence it is important to outline its distinctive features compared to other similar books. The book is well structured and well balanced." -Alfredo Vaccaro, University of Sannio, Italy

As the electric power industry faces the challenges of climate change, technological disruption, new market imperatives, and changing policies, a renowned energy expert offers a roadmap to the future of this essential sector. As the damaging and costly impacts of climate change increase, the rapid development of sustainable energy has taken on great urgency. The electricity industry has responded with necessary but wrenching shifts toward renewables, even as it faces unprecedented challenges and disruption brought on by new technologies, new competitors, and policy changes. The result is a collision course between a grid that must provide abundant, secure, flexible, and affordable power, and an industry facing enormous demands for power and rapid, systemic change. The fashionable solution is to think small: smart buildings, small-scale renewables, and locally distributed green energy. But Peter Fox-Penner makes clear that these will not be enough to meet our increasing needs for electricity. He points instead to the indispensability of large power systems, battery storage, and scalable carbon-free power technologies, along with the grids and markets that will integrate them. The electric power industry and its regulators will have to provide all of these, even as they grapple with changing business models for local electric utilities, political instability, and technological change. Power after Carbon makes sense of all the moving parts, providing actionable recommendations for anyone involved with or relying on the electric power system.
