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.
