Abstract
For the configuration optimization of energy storage system at the distribution network side, this paper analyzes the optimal configuration evaluation of the energy storage system in the distribution network. Firstly, a multi-objective optimal configuration model of the energy storage system of the distribution network is established, with load shifting, voltage quality and regulated power as three sub objectives. Then, the above-mentioned multi-objective optimal model is solved by the weighted minimum-modulus ideal-point method. And a variety of energy storage system configuration schemes is obtained by changing the weight of each sub-objective. Moreover, the evaluation index is established from the improvement degree of voltage quality and power regulation ability, and the analytic hierarchy process is employed to analyze the advantages and disadvantages of energy storage configuration schemes of distribution network. Finally, using MATLAB platform, the correctness of the above model is proved by a practical example.
