Research on Configuration Strategy of Optical Storage Charging Station

Abstract

Energy storage charging pile participating in the joint operation of power grid can not only reduce the cost of power grid expansion, but also obtain the benefit of participating in the auxiliary management service of power grid demand side response, so as to reduce operation cost. In this paper, energy storage charging pile is used to participate in the joint operation optimization of grid demand side response, and a model of optimal allocation of container energy storage in distribution network is proposed. Based on operation strategy of Optical storage charging station vehicle, the model aims to maximize investor's income in investment cycle, considering the income of participating in the voltage regulation, the subsidy income of delaying upgrading of distribution network, its investment and operation cost, and considering the constraints of voltage regulation of distribution network, the conversion of access nodes, energy conservation, etc., so as to optimize the number and rated capacity of Optical storage charging station vehicle. Finally, the case study of ieee33 node system is carried out. The results show that optimal configuration model can make investors of optical storage charging station gain profits and improve the economy of optical storage charging station.
