Abstract

This paper addresses the frequency regulation problem in paralleled inverter-based microgrid. A fully distributed adaptive control scheme is presented without the need for the central computer. With this method the frequency is regulated to its nominal value, while the power sharing of generators is maintained at the same time. By estimating the parameters on power lines adaptively, the distributed generators do not need prior knowledge of the microgrid system. The adaptive nature of the proposed controller yields a stable performance of the paralleled inverter system. Simulation examples illustrate the effectiveness of the proposed control method.
