New method on the relays protective coordination due to presence of distributed generation

The main purpose of this paper is to serve as a guideline for assessing the impact of distributed generation (DG) on the protection coordination of the distribution network. In particular, the paper details and presents a generalized assessment procedure for determining the impact of the integration of DG on the protection practices of distribution systems. To ensure the relevancy and the compatibility with the existing utility practices, demonstrations are carried out using ETAP, which are the commonly used software for distribution system protection planning.
