Abstract

Abstract: Aiming at optimization configuration of distributed energy storage in the distribution network， an economic indicator model and technical indicator model for energy storage access distribution network are established. An overall configuration optimization scheme of energy storage considering multi-scenario requirements is proposed to meet the interests of multi-agent of source network. The optimization models under different application scenarios of source， network and load side are established and the constraints that should be met are given. The second-order cone-based optimization method is used to transform the large-scale mixed integer nonlinear model into a mixed integer second-order cone optimization model， which improves the solution speed of the optimization problem. On the basis of the specific problems of energy storage configuration of a distribution network in a certain area， this paper optimizes the multi-scenario energy storage allocation in source， network and load side. Compared with the unified optimization scheme， the results show that the proposed multi-objective optimization configuration can be effectively applied to the optimal allocation of energy storage of the actual distribution network.

Key words: distributed energy storage configuration, multi-scene requrements, economic indicator, technical indicator, multi-objective optimization, second-order cone solution
