Abstract
A higher penetration of renewable energy sources and adoption of renewable portfolio standard(RPS), the penetration of distributed generators(DGs) into power distribution network is becoming a threat for the safe operation of distribution network. The ground fault current of DGs can cause parasitic trip and mal-trip of protective device in the power distribution network. KEPRI has developed a simulation program for current setting of protective devices in DGs connected distribution network. In this study, we analyzed fault currents of a sample network in two cases, i.e. case 1 is for no DG connection, case 2 for a DG connection. We performed protection coordination for relays installed in the network and analyzed the contribution of a DG.
