Distributed Power Sharing Control of Grid-Connected AC Microgrid with Uncertain Plant

Abstract

This paper considers the power sharing problem of a grid-connected AC microgrid where the system parameters of the dispatchable distributed generators are subject to arbitrarily large uncertainties. The power sharing problem is formulated as a tracking problem of an interconnected leader-follower multiagent system. In order to solve this tracking problem, an internal model principle based distributed control framework has been established.
