Abstract

An economic operation control strategy of island microgrid based on optimal scheduling of energy storage is proposed in this paper. The state of charge (SOC) and type of microgrid is fully considered in this strategy. In grid-tied island microgrid the energy storage charging control is carried out according to the SOC condition at valley electricity price, and the energy storage discharging control is carried out according to the SOC condition at peak electricity price. In stand-alone island microgrid the energy storage control of charging and discharging is carried out according to the renewable energy power generation and SOC value. The strategy proposed can effectively extend the battery life and improve the operation economy of microgrid making full use of price difference between peak and valley electricity price.
