In order to obtain more ideal energy storage capacity planning results,a new stochastic planning method for energy storage capacity of interconnected microgrid was proposed on the basis of considering the optimal power balance and demand response.Under the condition of demand response,based on the operation mode and stochastic theory of networked microgrid,the optimal power balance was taken as the planning goal,and the stochastic planning model of energy storage capacity was established.The particle swarm optimization algorithm was used to solve the stochastic programming model of energy storage capacity,and the optimal stochastic programming scheme of energy storage capacity of interconnected microgrid was obtained.The experimental results show that with the continuous increase of capacitance,the overall balance ability of microgrid becomes stronger.The energy balance index of the proposed method is higher,the rated capacity of energy storage is more stable,and the load of energy storage system is smaller,planning efficiency is higher.The proposed method can better realize the energy storage capacity planning of networked microgrid.
