A Two-Layer Control Architecture for Islanded AC Microgrids with Storage Devices

Abstract

Microgrids are considered of particular interest when it is necessary to integrate renewable energy sources and storage devices; furthermore, islanded operation is considered a possible solution to ensure power supply continuity for specific portions of distributions networks. In this paper a two-layer control architecture for islanded microgrids is proposed to take care of electrical variables regulation and of the resources optimization-based management. Simulation results are presented to validate the proposed control approach.
