Research on Economic Evaluation Method of Battery Energy Storage Peak

The ever-increasing peak-to-valley difference in load has led to a large amount of manpower and material resources for peak load and valley filling of power grids, and simple upgrading and expansion of power transmission and distribution lines, resulting in lower equipment utilization rates. Therefore, this paper proposes the use of battery energy storage system for peak distribution of the distribution network, through the energy storage system to achieve the benefits of charge and discharge. Firstly, on the basis of the existing typical peak load shifting control strategy, a power difference control strategy that is suitable for the peak load and valley fill of distribution network is proposed. Second, the battery energy storage system is applied to the power distribution. The actual situation of the network analyzed the economic benefits and investment costs of the energy storage system's participation in peak load reduction and valley filling. Finally, through the simulation analysis, the energy efficiency of the energy storage system participating in peak load shifting was evaluated.
