Abstract：With the continuous development of urban distribution network and new energy technology, problems such as heavy overload of substations, peaking and valley difference of power grid load, and insufficient absorption of new energy are becoming more and more serious. In view of the existing problems of distribution network, the centralized and large capacity energy storage system is firstly considered in substation nodes to give full play to the effect of peak cutting and valley filling. Secondly, the distributed and small capacity energy storage system is configured at the user node to promote the photovoltaic absorption, and the hierarchical energy storage optimization configuration model is established. Finally, the model is applied to a metal processing area, and the economy and effectiveness of the model are verified by simulation. The simulation results show that the established hierarchical energy storage system effectively reduces the peak-valley difference of substation load curve, promotes the photovoltaic absorption in the park, and reduces the annual comprehensive cost of users.
