Renewable Energy in Power Systems

The variable nature of most renewable energy sources needs special consideration when integrating such sources into traditional networks. Efficient power system operation requires that a number of activities be undertaken over wide time scales ranging form days to milliseconds. These activities include forecast demand, generation scheduling, security analysis, optimum economic dispatch and finally protection activities during system maloperation. These concepts are explained and the impact on the operation procedures of introducing increasing amounts of renewable energy is presented.Based upon a successful MSc course at Loughborough University, it considers the operation and structure of a modern electricity market, highlighting the differences between a centrally planned and operated system and a fully deregulated one. It includes many tables, diagrams, worked examples, tutorial questions, model answers and case studies to aid the learning process. It presents an introduction to solid-state switches and the way these switches are combined into AC/DC, DC/AC and AC/AC converters.
It discusses the regional and local operational benefits/problems that may result in the distribution network due to the injection of energy from renewables. It presents a critical analysis of the selling prices of electricity.
