Abstract

Summary: In this paper, a unified distributed robust control framework is proposed to address the power sharing problem for a cluster of dispatchable distributed generators (DDGs) within a grid‐connected AC microgrid. In contrast to the existing results, the advantages of the proposed control design are threefold. First, the unified design can directly handle the dynamics of the closed‐loop system by Lyapunov analysis without the assumption on time scale separation. Second, the canonical internal model is adopted so that the controller is able to undertake arbitrarily large parametric uncertainties. Last not least, the associated control gains can be obtained once and for all following the standard procedure. Comprehensive numerical simulations are provided for performance validation.
