Impact of dispersed generation in the power system performance

This paper deals with a study regarding the impact of distributed generation in the Electric System of RGE - one of the electric utilities of Brazilpsilas Southern Region - specifically concerning the integration of small hydroelectric plants (SHP) to the power system. Control and protection systems parameters characteristics have been taken into account and field-tests data have been obtained for simulation purposes. The information collected was used as input data into the mathematical model representing the RGE Distribution System. A computational tool was also developed to assist in data manipulation, for use in the simulations.
