Distributed Generation Technology
K.T.M.U. Hemapala, MK Perera · 2022
Distributed generation (DG) relates to various generating technologies that generate electricity at or near a utility. This concept is intended to serve a single structure such as a home or a business or a part of a microgrid, such as at a major industrial facility or a large college campus. DG is also referred to as cogeneration or small power production. Because of changes in energy demand and traditional economies of scale, distributed generation has become an emerging concept in place of centralized generation. DG encourages non-conventional renewable energy sources (NCREs) such as wind, solar photovoltaic, mini hydro, and biomass. In this chapter, an introduction to renewable energy resources, namely solar photovoltaic and wind generation, is presented, together with the science behind these technologies. Additionally, a brief introduction to energy storage systems is included.
