Abstract

Traditional interconnection standards avoid the islanding operation of distributed generators (DGs) because of concerns of equipment failure and safety. However, in some cases, allowing the islanding operation of DGs in a radial subtransmission system could improve system reliability and decrease outage cost during power outages or a scheduled maintenance. This paper presents an impact study on a DG connected to a radial subtransmission system. The dynamic study is conducted to show how to manage DGs and electric power systems for the proper intentional islanding in specific cases.
