Abstract :
This paper investigates the impact of Photovoltaic (PV) systems on the coordination between overcurrent relays in a PV-dominated distribution feeder. The paper shows under what conditions and how significant the PV systems affect the coordination. The paper also proposes a method for assessing the coordination in such feeders. Performance of the proposed methods has been assessed by simulations on a sample distribution feeder.
