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.

Condition monitoring of engineering plants has increased in importance as engineering processes have become increasingly automated. However, electrical machinery usually receives attention only at infrequent intervals when the plant or the electricity generator is shut down. The economics of industry have been changing, placing ever more emphasis on the importance of reliable operation of the plants. Electronics and software in instrumentation, computers, and digital signal processors have improved our ability to analyse machinery online. Condition monitoring is now being applied to a range of systems from fault-tolerant drives of a few hundred watts to machinery of a few hundred MW in major plants. This book covers a large range of machines and their condition monitoring. This 3rd edition builds on the 2nd edition through a major revision, update of chapters and a comprehensive list of references & standards. Permanent magnet, switched reluctance and other types of machines are now covered, as well as variable speed drive machines and off-line techniques. Contents cover an introduction to condition monitoring; rotating electrical machines; electrical machine construction, operation and failure modes; reliability of machines and typical failure rates; signal processing and instrumentation requirements; on-line temperature monitoring; on-line chemical monitoring; on-line vibration monitoring; on-line current, flux and power monitoring; on-line partial discharge (PD) electrical monitoring; on-line variable speed drive machine monitoring; off-line monitoring; condition-based maintenance and asset management; application of artificial intelligence techniques to CM; and safety, training and qualification.

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. Meeus, V. Rious, N. Rossetto, T. Schittekatte

This book discusses novel methods for planning and coordinating converters when an existing point-to-point (PtP) HVDC link is expanded into a multi-terminal HVDC (MTDC) system. It demonstrates that expanding an existing PtP HVDC link is the best way to build an MTDC system, and is especially a better option than the build-from-scratch approach in cases where several voltage-sourced converter (VSC) HVDC links are already in operation. The book reports in detail on the approaches used to estimate the new steady-state operation limits of the expanded system and examines the factors influencing them, revealing new operation limits in the process. Further, the book explains how to coordinate the converters to stay within the limits after there has been a disturbance in the system.

This book addresses the emerging trend of smart grids in power systems. It discusses the advent of smart grids and selected technical implications; further, by combining the perspectives of researchers from Europe and South America, the book captures the status quo of and approaches to smart grids in a wide range of countries. It describes the basic concepts, enabling readers to understand the theoretical aspects behind smart grid formation, while also examining current challenges and philosophical discussions. Like the industrial revolution and the birth of the Internet, smart grids are certain to change the way people use electricity. In this regard, a new term - the "prosumer" - is used to describe consumers who may sometimes also be energy producers. This is particularly appealing if we bear in mind that most of the distributed power generation in smart grids does not involve carbon emissions. At first glance, the option of generating their own power could move consumers to leave their current energy provider. Yet the authors argue that doing so is not a wise choice: utilities will play a central role in this new scenario and should not be ignored.
