Distributed Generation, Impact study ofdistribution network,


This paper presents a study to identify the impacts of multiple distributed generations on a distribution network. A case study in the Fang radial distribution network, a small system located in Thailand's Chiang Mai province is investigated. The Fang system is supplied with power from three distribution grid sources with extensive feeder length and six power plants: four small hydro power plants, one small geothermal power plant and one heavy oil power plant. The data concerning technical impacts on the system obtained from the local utility are analyzed. The result of this study shows that the impacts of connecting multiple distributed generations on distribution system are reliability, power losses and voltage profile.
