Abstract

Integrating Distributed Generation (DG) in distribution systems will have an impact on the fault current magnitudes. This could have an impact on the coordination of the protective devices. In this paper, the optimal DG locations are determined in order to minimize the overall relay operating times for a meshed distribution system. The problem is formulated as a Non-Linear Programming (NLP) problem and is solved using the reduced gradient approach. The relay operating times are minimized taking into account the protection coordination constraints where each relay is backed up by another relay on the system with a certain coordination time. In addition, constraints on the relay operating times and relay settings are included. The system under study is the IEEE meshed 30 bus distribution system with a protection system that relies on directional over-current relays.
