Eskom - Power, Politics And The (Post) Apartheid State (Paperback): Faeeza Ballim Eskom - Power, Politics And The (Post) Apartheid State (Paperback)
Faeeza Ballim
R280 R259 Discovery Miles 2 590 Save R21 (7%) In Stock

This riveting study shows how the intersection of technology and politics has shaped South African history since the 1960s.

It is impossible to understand South Africa’s energy crisis without knowing this history. Faeeza Ballim’s deeply researched book challenges many prevailing assumptions and beliefs made regarding the crisis.

The book highlights the importance of technology to our understanding of South African history and challenges the idea that the technological state corporations were proxies for the apartheid government. While a part of the broader national modernization project under apartheid, these corporations also set the stage for worker solidarity and trade union organization in the Waterberg and elsewhere in the country.

Faeeza Ballim argues that the state corporations, their technology, and their engineers enjoyed ambivalent relationships with the governments of their time. And in the democratic era, while Eskom has been caught up in the scourge of government corruption, it has retained a degree of organizational autonomy and offered a degree of resistance to those who were attempting further corrupt practices.

With the integration of more distributed or aggregated renewables, and the wide utilization of power electronic devices, modern power systems are facing new stability and security challenges, such as the weakly damped oscillation caused by wind farms connected through long distance transmission lines, the frequency stability problem induced by the reduction of inertia and the voltage stability issue resulting from the interactions between transmission systems and dynamic loads. Meanwhile, synchronized phasor measurement technology developed very fast in the last decade, and more phasor measurement units (PMUs) and wide area measurement systems (WAMSs) have been deployed. These provide more insights into the system dynamics and approaches to overcoming the new challenges. This book addresses the emerging concepts, methodologies and applications of wide area monitoring, control and protection in power systems with integrated large scale renewables. Chapters cover monitoring, modelling and validation, control, and data mining with an emphasis on synchrophasor technology, and experiences with real power grids.

Electric Utility Resource Planning - Economics, Reliability, and Decision-Making (Hardcover): Steven Sim Electric Utility Resource Planning - Economics, Reliability, and Decision-Making (Hardcover)
Steven Sim
R3,131 Discovery Miles 31 310 Ships in 12 - 17 working days

Most people-including many legislators, regulators, and other decision makers in the electric utility industry-have misconceptions about how electric utilities really "work" and plan for the future. This lack of understanding can lead to poorly informed decisions and policies that directly affect the choices utilities must make. Using easy-to-understand text and examples, Electric Utility Resource Planning: Economics, Reliability, and Decision-Making clarifies how utilities operate their systems and prepare for the future. This explanation will show readers that both expected and counterintuitive results can occur (i.e., conservation might result in higher air emissions, or lowering costs could lead to higher electric rates). Taking readers step by step through this process, the book (in the following order): "Creates" a hypothetical utility Explains how and why a utility operates its system of generating units Discusses the planning methods that a utility would (or should) use Guides readers through each stage of a planning analysis for the hypothetical utility, examining various resource options (conservation, new power plants, and solar) In addition, the author introduces four Fundamental Principles of Resource Planning that should guide utilities. He also offers opinions on how certain trends in utility regulation and legislation can hinder utility planners' efforts to identify and select the best resources for the utility's customers. With this book, author Dr. Steven Sim applies his experience and insights from more than two decades of resource planning for Florida Power and Light (FPL). As one of the largest utilities in the United States, FPL has faced a multitude of resource planning challenges, and Dr. Sim has performed and supervised thousands of analyses designed to meet these obstacles. He has also served as an FPL witness in regulatory hearings on a wide variety of topics, ranging from the economic implications of nuclear, conservation, coal, gas, and other resource options, to the non-economic impacts (air emissions, fuel usage, system reliability, etc.) they present.

Leonardo Meeus, Jean-Michel Glachant
R2,977 Discovery Miles 29 770 Ships in 12 - 17 working days

The UK model of incentive regulation of power grids was at one time the most advanced, and elements of it were adopted throughout the EU. This model worked well, particularly in the context of limited investment and innovation, a single and strong regulatory authority, and limited coordination between foreign grid operators. This enlightening book demonstrates how the landscape has changed markedly since 2010 and that regulation has had to work hard to catch up and evolve. As the EU enters a wave of investment and an era of new services and innovation, this has created growing tensions between national regulatory authorities in terms of coordinating technical standards and distribution systems. This is being played out against an increasingly disruptive backdrop of digitization, new market platforms and novel business models. Electricity Network Regulation in the EU adopts a truly European approach to the complex issues surrounding the topic, focusing on the grey areas and critical questions that have traditionally been difficult to answer. Incentive regulation and grids are addressed simultaneously at the theoretical and practical level, providing the reader with fundamental concepts and concrete examples. This timely book is an invaluable read for energy practitioners working in utility companies, regulators and other public bodies. It will also appeal to academics involved in the world of electricity regulation. The book utilizes language that would make it suitable for interdisciplinary students, including engineering and law scholars. Contributors include: P. Bhagwat, J.-M. Glachant, S.Y. Hadush, L.

The intermittency of renewable energy sources is making increased deployment of storage technology necessary. Technologies are needed with high round-trip efficiency and at low cost to allow renewables to undercut fossil fuels. The cost of lithium batteries has fallen, but producing them comes with a substantial carbon footprint, as well as a cost to the local environment. Compressed air energy storage (CAES) uses excess electricity, particularly from wind farms, to compress air. Re-expansion of the air then drives machinery to recoup the electric power. Prototypes have capacities of several hundred MW. Challenges lie in conserving the thermal energy associated with compressing air and leakage of that heat, materials, power electronics, connection with the power generator, and grid integration. This comprehensive book provides a systematic overview of the current state of CAES technology. After an introduction to motivation and principles, the key components are covered, and then the principal types of systems in the order of technical maturity: diabatic, adiabatic, and isothermal. Experts from industry write about their experiences with existing major systems and prototypes. Economic aspects, power electronics and machinery, as well as special systems for offshore applications, are dealt with. Researchers in academia and industry alike, in particular at energy storage technology manufacturers and utilities, as well as advanced students and energy experts in think tanks will find this work valuable reading.

Nanogrids are small energy grids, powered by various generators often including photovoltaics. For example, a nanogrid might supply a village in a rural area and allow that village to trade its surplus energy. A picogrid is a still smaller energy grid. IRENA defines nanogrids as systems handling up to 5 kW of power while picogrids handle up to 1 kW. Nanogrids and picogrids can play roles in urban, suburban and rural areas, particularly in developing countries, and can help with decarbonising the energy systems and empowering citizens. Electric vehicles (EV) are poised to play important roles and need to be accounted for in emerging and future small grids. This book introduces the principles of nano- and picogrids, then goes on to provide a technical analysis covering connected resources, modelling and performance, power quality and protection. The use of nano- and picogrids in conjunction with EV, charger technologies, the IoT, cloud computing and data sharing is explored. Case studies of real-life projects help readers to understand and apply the concepts for their own projects. Nanogrids and Picogrids and their Integration with Electric Vehicles is a valuable resource for researchers involved with power systems, particularly those with an interest in power supply in rural areas, or anyone with a particular interest in nano- and microgrids. It is also of use to advanced students, and to engineers working in utilities.
