Abstract In this study, a pinning-based distributed predictive control of secondary voltage is proposed for an autonomous microgrid (MG) with communication constraints. The proposed predictive control is fully distributed, which requires the information of each distributed generator (DG) on an islanded microgrid and that of its neighbors. In particular, the predictive control scheme can compensate for the communication constraints actively rather than passively. Moreover, it could reduce the computation burden of the controller owing to the developed pinning-based control scheme. It is worthwhile to mention that the purpose of voltage restoration based on distributed predictive control is achieved by minimization of the utility function, which not only ensures the feasibility of the control input but also restores the voltage of an autonomous microgrid to a prescribed level simultaneously through an introduction of tracking and coordination cost. Finally, simulation results are presented to validate the effectiveness of the proposed control methodology.
