| Abstract: | The energy consumption statistics of buildings shows that cooling takes up a considerable portion of the energy demand. The peak–valley characteristics of cooling demand coincides with that of the electrical load in the microgrid. Thus the management of the cooling demand side can regulate the peak–valley demand and stabilize power fluctuations. This paper proposes a new energy management strategy that reduces the investment and loss of the battery energy storage system (BESS ) by applying ice storage air‐conditioning (ISAC ) to the microgrid. Based on the load characteristics and BESS investment, the capacities of the chillers and the ice tank are analyzed. Penalty functions of ISAC and BESS are designed, according to which the stabilization command is dispatched. Finally, an actual case is analyzed by the proposed strategy, and the results verify the feasibility and effectiveness of the energy management strategy. © 2016 Institute of Electrical Engineers of Japan.
