Investigating the electric power distribution system (EPDS) bus voltage in the presence of distributed generation (DG)

This paper investigates the Electric Power Distribution System (EPDS) bus voltage in the presence of Distributed Generation (DG). Distribution Company's (Discos) planner endeavor to develop new planning strategies for their network in order to serve the load growth and provide their customers with a reliable electric supply. In this research work, five different cases including preplanned islanding and grid-connected mode has been discussed. The studies are performed based on well known software package PSCAD/EMTDC. The work shows that presence of DG provides a significant support to EPDS in term of power quality and voltage stability of bus voltage.
