Energy Storage System Optimization Strategy in the Distribution Network Based on Active Set Method

On the basis of short-term power load data, an active set algorithm based energy storage system optimization strategy in the distribution network is presented in this paper. When energy storage system is connected to the power grid, the original load and output power of energy storage system is considered as the new network load. In order to improve the reliability and power supply capability of the distribution network, methods should be taken to make the new load curve as smooth as possible. Therefore the minimum variance in load curve is used as the objective function of optimization model of energy storage system. The active set method is adopted to solve the problem. The result shows that the active set method is effective in solving the optimization strategy in the distribution network.
