Something good about the smart city: a human-centered account of why the future of electricity is local. Resilience now matters most, and most resilience is local—even for that most universal, foundational modern resource: the electric power grid. Today that technological marvel is changing more rapidly than it has for a lifetime, and in our new grid awareness, community microgrids have become a fascinating catalyst for cultural value change. In Downtime on the Microgrid, Malcolm McCullough offers a thoughtful counterpoint to the cascade of white papers on smart clean infrastructure. Writing from an experiential perspective, McCullough avoids the usual smart city futurism, technological solutionism, policy acronyms, green idealism, critical theory jargon, and doomsday prepping to provide new cultural context for a subject long a favorite theme in science and technology studies. McCullough describes the three eras of North American electrification: innovation, consolidation, and decentralization. He considers the microgrid boom and its relevance to the built environment as “architecture's grid edge.” Finally, he argues that resilience arises from clusters; although a microgrid is often described as an island, future resilience will require archipelagos—clusters of microgrids, with a two-way, intermittent connectiveness that is very different from the always-on, top-down technofuture we may be expecting. With Downtime on the Microgrid, McCullough rises above techno-hype to find something good about the smart city and reassuring about local resilience.

This book discusses various challenges and solutions in the fields of operation, control, design, monitoring and protection of microgrids, and facilitates the integration of renewable energy and distribution systems through localization of generation, storage and consumption. It covers five major topics relating to microgrid i.e., operation, control, design, monitoring and protection. The book is primarily intended for electric power and control engineering researchers who are seeking factual information, but also appeals to professionals from other engineering disciplines wanting an overview of the entire field or specific information on one aspect of it. Featuring practical case studies and demonstrating different root causes of large power failures, it helps readers develop new concepts for mitigating blackout issues. This book is a comprehensive reference resource for graduate and postgraduate students, academic researchers, and practicing engineers working in the fields of power system and microgrid.

Microgrid technology is an emerging area, and it has numerous advantages over the conventional power grid. A microgrid is defined as Distributed Energy Resources (DER) and interconnected loads with clearly defined electrical boundaries that act as a single controllable entity concerning the grid. Microgrid technology enables the connection and disconnection of the system from the grid. That is, the microgrid can operate both in grid-connected and islanded modes of operation. Microgrid technologies are an important part of the evolving landscape of energy and power systems. Many aspects of microgrids are discussed in this volume, including, in the early chapters of the book, the various types of energy storage systems, power and energy management for microgrids, power electronics interface for AC & DC microgrids, battery management systems for microgrid applications, power system analysis for microgrids, and many others. The middle section of the book presents the power quality problems in microgrid systems and its mitigations, gives an overview of various power quality problems and its solutions, describes the PSO algorithm based UPQC controller for power quality enhancement, describes the power quality enhancement and grid support through a solar energy conversion system, presents the fuzzy logic-based power quality assessments, and covers various power quality indices. The final chapters in the book present the recent advancements in the microgrids, applications of Internet of Things (IoT) for microgrids, the application of artificial intelligent techniques, modeling of green energy smart meter for microgrids, communication networks for microgrids, and other aspects of microgrid technologies. Valuable as a learning tool for beginners in this area as well as a daily reference for engineers and scientists working in the area of microgrids, this is a must-have for any library.
