Introduction to Hybrid Energy System

Abstract

With a rapid increase in global energy demand, it is difficult to provide energy only with one type of energy source. Conventionally, fossil fuel-based energy generation is utilized for fulfilling global energy requirements. However, it is adversely impacting the environment and is a major obstacle to achieving sustainable goals. Therefore, a hybrid energy system is required to overcome the energy requirements as well as provide solutions against emissions from the burning of fossil fuels. The utilization of renewable energy sources (RESs) such as solar and wind in a hybrid energy system is accepted globally. There are various combinations that can be obtained in a hybrid energy system, viz. solar-wind, solar-battery storage, wind-battery storage, solar-wind-battery storage, and solar-wind-diesel generator-battery. Generally, fossil fuel-based energy sources such as diesel engine generators (DEGs) are provided as backups during extreme weather conditions, which restrict the power generation from the RESs. This chapter provides insight into various types of hybrid energy systems, their characteristics, and their use.
