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.

Ice storage air conditioning is the process of using ice for thermal energy storage. The process can reduce energy used for cooling during times of peak electrical demand. Alternative power sources such as solar can also use the technology to store energy for later use. This is practical because of water''s large heat of fusion: one metric ton of water (one cubic metre) can store 334 megajoules (MJ…
