A novel load flow analysis for particle-swarm optimized microgrid power sharing

Abstract

This paper proposes a novel load flow analysis (LFA) for droop-based islanded microgrids (DBIM). The standard LFA cannot be used since no single node sets the reference voltage. As the voltage in the islanded microgrid depends on the droop relation, they are included them as part of load flow equations. The proposed LFA is used with particle swarm optimization to select the droop parameters that optimize the power sharing among sources in a microgrid. The proposed methods are found to be effective through simulation studies.
