Communicative Scheduling of Integrated Microgrids

Abstract

A Provisional Microgrid (PMG) is a specific and promising type of microgrid that enhances the utilization of renewable energy resources in an efficient and cost-effective manner. The PMGs, however, must be electrically integrated to an existing microgrid, called a coupled microgrid (CMG), for islanded operation. This paper proposes a communicative optimal scheduling model in which the local power exchange between a PMG and a CMG is determined through iterative exchange of relevant information. The final solution will ensure a reduced load curtailment in PMG and a higher economic benefit for the CMG. The proposed model is mathematically formulated using mixed-integer programming, and studied through numerical simulations to show performance and effectiveness.
