The book focuses on describing the emerging microgrid concept, and its various constituents, especially the EV technology, and investigates the load frequency control performance of different microgrid configurations by implementing the modern control theory. An exhaustive study is presented on the various renewable energy sources and an up-to-date status of their installed capacity and power generation. The text presents case studies for load frequency control of a microgrid in its various operating modes. This book: Discusses power system stability, significance of load frequency control in power system, modeling of a microgrid, and frequency deviation response. Covers various energy storage technologies such as superconducting magnetic energy storage, electrochemical energy storage, and compressed air energy storage. Presents modes of interaction of the electric vehicles with the utility grid and implementation of the electric vehicles for load frequency control. Illustrates control approaches for load frequency control and metaheuristic optimization algorithms. Showcases the study of load frequency control for standalone microgrid systems, grid-connected microgrid systems, and multi-microgrid systems. It is primarily written for senior undergraduates, and graduate students in the fields of electrical engineering, electronics, communication engineering, and renewable energy.
