PEA Guidelines of Impact Study and Operation of DG for Islanding Operation

Since intentional islanding operation of Distributed Generation (DG) can increase system reliability, and reduce the customer outage cost due to loss of power supply from main grid, some utilities may permit islanding operation of DG. As a result, the impact study and operation criteria of DG for island operation should be performed. Provincial Electricity Authority (PEA) is increasingly interested in islanding operation. In order to perform islanding operation, PEA has to establish the islanding operation and impact study guidelines of DG. This paper presents the development of these guidelines. The study case is conducted to demonstrate results of impact study of both steady-state and dynamic analysis. The operation issues also take into account in this paper.
