In this paper, the relationship between the economic indicators of an energy storage system and its configuration is first analyzed, and the optimization objective function is formulated. But energy storage programs must be strategically and intentionally designed to achieve peak demand reduction; otherwise, battery usage may not efectively lower demand peaks and may even increase peaks and/or greenhouse gas emissions in some circumstances. Under these circumstances, the power grid faces the challenge of peak shaving. Each strategy for managing peak load presents potential. . Abstract:The optimal configuration of the rated capacity, rated power and daily output power is an important prerequisite for energy storage systems to participate in peak regulation on the grid side. Economic benefits are the main reason driving investment in energy storage systems. Implementation: Battery Energy Storage Systems (BESS) are typically used to store electricity during off-peak hours when it is cheaper and. .
