Description
Summary:This paper proposes an optimal power scheduling strategy for cooperative operation of multiple-coupled microgrids, where the microgrid coalition makes day-ahead energy exchange commitments with the grid. Deviations from their commitments are limited by penalizing the microgrids. Various system intermittencies are captured via scenarios. The framework aims at maximizing the expected profit of each microgrid, while mitigating the distribution power losses by enabling local power trades between all microgrids within a coalition. The scheduling problem only utilizes the power exchange requests as the control signals between participating microgrids. Extensive numerical results are presented to corroborate the efficacy of the proposed approach.
