Impact of distributed generation on Voltage regulation in the distribution system (Case study: Rwanda)

Abstract

Distributed Generation (DG) is the energy generating from a variety of small sources of energy source, such as small hydropower plant, solar and wind, those are located close to the user. On-site generation is a type of DG in which a customer owns the generation and it is installed on its premises. The inserting of distributed generation on a distribution network can have an effect on voltage adjuster. A Distributed Generation may in some cases provide voltage support but it may as well as cause a grid challenge depending on several variables such as intermittent distributed generation, atmospheric conditions, solar irradiance, DG location, and voltage regulation method. The impact of DG was studied by analysis of data collected at Rwanda National Control Center and using Power World simulator.
