【 摘 要 】

This paper presents a novel algorithm for representing the effects of an optimal configuration of distribution energy storage system (DESS). The method was developed in the context of a framework in power distribution network with DESS, which includes such considerations as: SOC, cost of energy storage device, electricity price, transmission losses. The presented method provides a means for computing an optimal schedule of DESS energy resource allocation for new energy sources and loads power fluctuation, which can synthesize all useful energy storage devices, that is better for system stability and is contributed to the interests of energy storage owners, because energy storage device usually cannot be used adequately. Of particular interest, the method considers the relation between the depth of discharge and the use-cost of different energy storage device and the influences of transmission losses.
