Sustainable Power Systems

This book deals with quantifying and analyzing the risks associated with sustainable energy technology growth in electric power systems, and developing appropriate models and methodologies to mitigate the risks and improve the overall system performance. The rapid increase in the installation of renewable energy sources in electric power systems have given rise to a wide range of problems related to the planning and operation of power systems to maintain quality, stability, reliability and efficiency. In addition, there is growing global environmental concern regarding increasing emissions from the electric power generation required to meet rising energy needs and support sustainable and inclusive development. The phenomenon of low voltage ride through common to wind energy systems is discussed, and ways to tackle the same are proposed in the first chapter. The second chapter proposes methods of optimizing a sustainable and smart microgrid. The next chapter deals with supplying electricity to remote areas of a developing country with no immediate possibility of national grid extension. The economic benefit and technical challenges of forming localized minigrid are discussed in the chapter. The fourth chapter proposes a method for reliability assessment of a power grid with sustainable power transportation system. The issue of weak link in power system is very important as it will provide the system operators and planners to take necessary measures to strengthen the system. An approach to determine the weak parts of the system and its unreliability is proposed in the next chapter. With increasing installation of HVDC power transmission and development of efficient and low cost power electronic devices, the DC microgrids are becoming a common phenomenon. Their existence together with AC Grids result in Hybrid AC/DC Microgrids, and these are discussed in this book. The last chapter presents a method for reliability evaluation of a distribution system with network reconfiguration in the presence of distributed generation. The important problems in sustainable energy growth, and their potential solutions are discussed and presented in the book, which should be of great interest to engineers, policy makers, researchers and academics in the area of electric power engineering.§
