To maximize the economic aspect of configuring energy storage, in conjunction with the policy requirements for energy allocation and storage in various regions, the paper clarified the methods for configuring distributed energy storage systems and summarized. Due to the development of renewable energy and the requirement of environmental friendliness, more distributed photovoltaics (DPVs) are connected to distribution networks. The optimization of stable operation and the improvement of DPV hosting capacity are urgently needed. Firstly. To address this issue, this paper builds upon conventional distribution network resilience assessment methods by supplementing and modifying indices in the dimensions of resistance and recovery to account for power quality issues. Furthermore, an optimized energy storage system (ESS) configuration. New energy policies, cost-effective technologies, and customer preferences for electric transportation and clean energy are transforming power system planning and operations, particularly at the distribution grid where consumers and businesses connect to the grid.
