Energy flow from many primary sources is not constant but depends on the season, time of day and weather conditions. Energy demand also varies with the same circumstances, but generally in reverse. Obviously there needs to be some way for energy suppliers to separate the processes of energy generation and consumption, by storing energy until it is needed.Electricity is the most flexible and convenient form of energy for transmission and use but it is not economically possible to store electrical energy in significant quantities. Secondary energy storage systems can accept energy generated by a power system, convert it to a form suitable for storage, keep it for a certain time and then convert it into the form required by the consumer when it is needed. These systems are an essential tool in managing energy supplies.This book is a comprehensive guide to the various types of secondary storage systems and an introduction to the multidisciplinary problem of choice of their types and parameters. It is chiefly aimed at students of electrical and power engineering, and design and research engineers concerned with the logistics of power supply. It will also be valuable to all those interested in the development of environmentally benign power supplies.

Unregulated distributed energy sources such as solar roofs and windmills and electric vehicle requirements for intermittent battery charging are variable sources either of electricity generation or demand. These sources impose additional intermittent load on conventional electric power systems. As a result thermal power plants whose generation is absolutely essential for any power system are increasingly being used for cycling operations thus increasing greenhouse gas emissions and electricity cost. The use of secondary energy storage might be a solution. Various technologies for storing electric energy are available; besides electrochemical ones such as batteries, there are mechanical, chemical and thermal means, all with their own advantages and disadvantages regarding scale, efficiency, cost, and other parameters.This classic book is a trusted source of information and a comprehensive guide to the various types of secondary storage systems and choice of their types and parameters. It is also an introduction to the multidisciplinary problem of distributed energy storage integration in an electric power system comprising renewable energy sources and electric car battery swap and charging stations.The 3rd edition has been thoroughly revised, expanded and updated. All given data has been updated, and chapters have been added that review different types of renewables and consider the possibilities arising from integrating a combination of different storage technologies into a system. Coverage of distributed energy storage, smart grids, and EV charging has been included and additional examples have been provided. The book is chiefly aimed at students of electrical and power engineering and design and research engineers concerned with the logistics of power supply. It will also be valuable to general public seeking to develop environmentally sound energy resources.
