Introduction to DC Microgrids

Discover the art and science of designing, building, and installing DC microgrid systems with this authoritative resource Introduction to DC Microgrids delivers a comprehensive and concise introduction to the fundamentals of DC microgrid technology. Beginning with the basic concepts of DC systems and their various constituents, the book moves on to a variety of DC architectures and voltage levels of DC microgrid systems. Typical examples, use cases, and applications round out the material to form a practical and accessible resource ideal for students, professionals, and enthusiasts. Accomplished engineers and authors, Vivek Agarwal and Prajof Prabhakaran, offer readers solved numerical examples in every chapter to shore up the theoretical concepts presented. They also discuss different types of power converters used in several roles in DC microgrid systems and common issues faced by those who install and use them. Introduction to DC Microgrids makes a compelling case for the merits of using DC microgrids over AC solutions and includes usable techniques to determine optimal placement of loads and sources. You’ll also learn from: A complete introduction to DC microgrid systems with discussions of a variety of reported architectures and voltage levels A fulsome description of power electronic converters in DC microgrid systems with simulation and experimental results of several different converters An explanation of DC microgrid control methods, including novel control techniques to minimize voltage regulation and improve load sharing accuracy A treatment of power quality and protection of DC microgrids, including a discussion of how to mitigate voltage fluctuation and harmonic issues Perfect for doctoral, graduate, and senior undergraduate students in electrical engineering and related programs, Introduction to DC Microgrids also has a place on the bookshelves of diploma students, technicians who install and implement microgrid systems in the field, and industrial professionals interested in electrical sustainability projects.
DC Microgrids

DC MICROGRIDS Written and edited by a team of well-known and respected experts in the field, this new volume on DC microgrids presents the state-of-the-art developments and challenges in the field of microgrids for sustainability and scalability for engineers, researchers, academicians, industry professionals, consultants, and designers. The electric grid is on the threshold of a paradigm shift. In the past few years, the picture of the grid has changed dramatically due to the introduction of renewable energy sources, advancements in power electronics, digitalization, and other factors. All these megatrends are pointing toward a new electrical system based on Direct Current (DC). DC power systems have inherent advantages of no harmonics, no reactive power, high efficiency, over the conventional AC power systems. Hence, DC power systems have become an emerging and promising alternative in various emerging applications, which include distributed energy sources like wind, solar and Energy Storage System (ESS), distribution networks, smart buildings, remote telecom systems, and transport electrification like electric vehicles (EVs). All these applications are designed at different voltages to meet their specific requirements individually because of the lack of standardization. Thus, the factors influencing the DC voltages and system operation needed to be surveyed and analyzed, which include voltage standards, architecture for existing and emerging applications, topologies and control strategies of power electronic interfaces, fault diagnosis and design of the protection system, optimal economical operation, and system reliability.
Risk-Based Energy Management

Risk-Based Energy Management: DC, AC and Hybrid AC-DC Microgrids defines the problems and challenges of DC, AC and hybrid AC-DC microgrids and considers the right tactics and risk-based scheduling to tackle them. The book looks at the intermittent nature of renewable generation, demand and market price with the risk to DC, AC and hybrid AC-DC microgrids, which makes it relevant for anyone in renewable energy demand and supply. As utilization of distributed energy resources and the intermittent nature of renewable generations, demand and market price can put the operation of DC, AC and hybrid AC-DC microgrids at risk, this book presents a timely resource.
