Research on Optimal Allocation Method of Energy Storage Considering Supply and Demand Flexibility and New Energy Consumption

In order to effectively improve the utilization rate of new energy, based on the mature optimal allocation of energy storage and considering the characteristics of supply and demand balance, the reasonable integration and unified planning and configuration of various energy forms are carried out. Firstly, considering the demand of energy storage system in the system, a flexible supply and demand model is established; secondly, according to the flexible supply and demand model, the joint supply and demand balance margin of new energy and energy storage system is set Finally, the optimal allocation of energy storage is carried out with the objective of minimizing the comprehensive cost of the system including construction cost, operation cost and depreciation cost in the cycle. The simulation results show that this configuration method can effectively make up for the deficiencies of the original energy system in separate planning and independent operation, break the energy barrier, improve the energy utilization efficiency, and optimize energy system structure.
