Abstract

In this paper, we consider the problem of designing a distributed algorithm, resilient against communication delays and packet drops, for coordinating the response of distributed energy resources (DERs) in AC microgrids so as to minimize electrical line losses and generation cost, and to ensure that the microgrid network constraints are satisfied. The proposed algorithm can be utilized as a secondary or tertiary controller for frequency regulation in islanded microgrids, or to coordinate DERs for providing frequency regulation services to the bulk grid when microgrid is in grid-connected mode. We validate the practical usefulness of the theoretical results through numerical simulations involving the IEEE 39-bus system.
