Energy management of cooperative microgrids with high‐penetration renewables

In view of the tremendous benefits induced by cooperative operation of microgrids, such as reduced power loss, lower operational cost and load peak reduction, this study presents a new energy management strategy for coalition forming microgrids under an electricity market environment. The proposed framework models the time‐variant and intermittent attribute of renewable energy sources using a worst‐case transaction mechanism. The energy management strategy minimises the net operating cost of the microgrids forming the coalition, which not only includes the cost of distributed generation but a worst‐case net transaction cost to account for the intermittency in renewable energy‐based sources. Extensive numerical results are shown to corroborate the efficacy of the proposed framework.
