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.

Coal- and gas-based power plants currently supply the largest proportion of the world s power generation capacity, and are required to operate to increasingly stringent environmental standards. Higher temperature combustion is therefore being adopted to improve plant efficiency and to maintain net power output given the energy penalty that integration of advanced emissions control systems cause. However, such operating regimes also serve to intensify degradation mechanisms within power plant systems, potentially affecting their reliability and lifespan.

Understand microgrids and networked microgrid systems Microgrids are interconnected groups of energy sources that operate together, capable of connecting with a larger grid or operating independently as needed and network conditions require. They can be valuable sources of energy for geographically circumscribed areas with highly targeted energy needs, and for remote or rural areas where continuous connection with a larger grid is difficult. Microgrids' controllability makes them especially effective at incorporating renewable energy sources. Microgrids: Theory and Practice introduces readers to the analysis, design, and operation of microgrids and larger networked systems that integrate them. It brings to bear both cutting-edge research into microgrid technology and years of industry experience in designing and operating microgrids. Its discussions of core subjects such as microgrid modeling, control, and optimization make it an essential short treatment, valuable for both academic and industrial study. Readers will acquire the skills needed to address existing problems and meet new ones as this crucial area of power engineering develops. Microgrids: Theory and Practice also features: Incorporation of new cyber-physical system technologies for enabling microgrids as resiliency resources Theoretical treatment of a wide range of subjects including smart programmable microgrids, distributed and asynchronous optimization for microgrid dispatch, and AI-assisted microgrid protection Practical discussion of real-time microgrids simulations, hybrid microgrid design, transition to renewable microgrid networks, and more Microgrids: Theory and Practice is ideal as a textbook for graduate and advanced undergraduate courses in power engineering programs, and a valuable reference for power industry professionals looking to address the challenges posed by microgrids in their work.

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.

Microgrids have emerged as a promising solution for accommodating the integration of renewable energy resources. But the intermittency of renewable generation is posing challenges such as voltage/frequency fluctuations, and grid stability issues in grid-connected modes. Model predictive control (MPC) is a method for controlling a process while satisfying a set of constraints. It has been in use for chemical plants and in oil refineries since the 1980s, but in recent years has been deployed for power systems and electronics as well. This concise work for researchers, engineers and graduate students focuses on the use of MPC for distributed renewable power generation in microgrids. Fluctuating outputs from renewable energy sources and variable load demands are covered, as are control design concepts. The authors provide examples and case studies to validate the theory with both simulation and experimental results and review the shortcomings and future developments. Chapters treat power electronic converters and control; modelling and hierarchical control of microgrids; use of MPC for PV and wind power; voltage support; parallel PV-ESS microgrids; secondary restoration capability; and tertiary power flow optimization.

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.

Large rural areas in some regions of the world are still grappling with the challenge of electrification. The optimal solution is to provide reliable energy without adding more fossil fuel plants by using distributed renewable generation. Microgrids are part of that solution; they are small networks of electricity users, with a local generator that is attached to a centralized larger grid, but which is also able to function independently. They need to be robust and resilient in order to provide reliable power, including in harsh climates. For remote areas microgrids have the advantage of offering an electricity supply even if there are problems with the larger power grid. This book focuses on the challenges of rural electrification, particularly in poorer regions. It covers low voltage DC distribution system for various applications including charging of electric vehicles (EV). Written by a large team of authors with a wide range of relevant experiences, the book addresses microgrid architectures, converters, energy storage, control, EV integration, business models and economic scheduling, and the role of blockchain technology.
