Performance indices and objectives for microgrids

This paper gives recommendations to researchers and developers on how to evaluate the performance of microgrids during island operation. A microgrid is a small grid including distributed energy resources and loads that can operate independently in the case of emergency of distribution systems. During island operation, the performance requirements of microgrids could be different than those during interconnected operation. To quantify the performance of microgrids, we propose a number of performance indices for voltage quality and reliability.
