In modern society, the utility power grid is supposed to guarantee load management, demand side management, as well as to use the market price of electricity and forecasting of energy (eg: based on wind and solar renewable sources) in order to optimise the whole electrical distribution system. An optimised power system is expected to have the following characteristics: high efficiency, high availability, good quality of service and high level of security, which leads to the concepts of distributed generation and smart-grid. This book discusses different emerging technologies, principles and applications of power electronics and hydroelectric power. Some of the topics discussed include parallel three-phase back-to-back converters; risk management of hydropower projects; and cascade converters for wide conversion ratios.

The ongoing search for renewable energy, the societal impact of blackouts, the environmental impact of generating electricity, along with the new ABET criterion have contributed to renewed interest in electric energy as a core subject. Emphasizing modeling, analysis, and real-world issues, this new edition of Electric Energy provides a refreshed overview of this increasingly important field. New in the Second Edition— · Expanded coverage of the mathematical modeling of renewable systems, power electronics, and electric safety · A chapter on power quality · An expanded chapter on machines that includes dc machines and single phase motors · A chapter on future power systems Along with the standard topics of power electronics and electromechanical conversion, the text also covers energy resources, power plants, environmental impacts of power generation, power system operation, renewable energy, and electrical safety. Most of the topics are related to issues encountered daily in practice, and most of the examples are from real systems and use real data. With a flexible structure and exceptional relevance to real-life issues, Electric Energy, Second Edition brings together all the topics needed to build the broad-based background today’s engineers need.

While most books approach power electronics and renewable energy as two separate subjects, Power Electronics for Renewable and Distributed Energy Systems takes an integrative approach; discussing power electronic converters topologies, controls and integration that are specific to the renewable and distributed energy system applications. An overview of power electronic technologies is followed by the introduction of various renewable and distributed energy resources that includes photovoltaics, wind, small hydroelectric, fuel cells, microturbines and variable speed generation. Energy storage systems such as battery and fast response storage systems are discussed along with application-specific examples. After setting forth the fundamentals, the chapters focus on more complex topics such as modular power electronics, microgrids and smart grids for integrating renewable and distributed energy. Emerging topics such as advanced electric vehicles and distributed control paradigm for power system control are discussed in the last two chapters. With contributions from subject matter experts, the diagrams and detailed examples provided in each chapter make Power Electronics for Renewable and Distributed Energy Systems a sourcebook for electrical engineers and consultants working to deploy various renewable and distributed energy systems and can serve as a comprehensive guide for the upper-level undergraduates and graduate students across the globe.

Introduces the history, uses, production, advantages and disadvantages, and future of hydroelectric energy as a power resource.

This book reports on a comprehensive study addressing the dynamic responses of hydropower plants under diverse conditions and disturbances, and analyzes their stability and oscillations. Multiple models based on eight existing hydropower plants in Sweden and China were developed and used for simulations and theoretical analysis with various degrees of complexity and for different purposes, and compared with on-site measurements for validations. The book offers important insights into the understanding of the hydraulic, mechanical and electrical coupling mechanisms, up to market conditions and incentives. It recommends control strategies for a more stable and efficient operation of hydropower plants.

“Power Electronics in Smart Electrical Energy Networks” introduces a new viewpoint on power electronics, re-thinking the basic philosophy governing electricity distribution systems. The proposed concept fully exploits the potential advantages of renewable energy sources and distributed generation (DG), which should not only be connected but also fully integrated into the distribution system in order to increase the efficiency, flexibility, safety, reliability and quality of the electricity and the networks. The transformation of current electricity grids into smart (resilient and interactive) networks necessitates the development, propagation and demonstration of key enabling cost-competitive technologies. A must-read for professionals in power engineering and utility industries, and researchers and postgraduates in distributed electrical power systems, the book presents the features, solutions and applications of the power electronics arrangements useful for future smart electrical energy networks.
