      In recent years, with the improvement of technology performance of energy storage system, reduction of cost, the prominent contradiction between power supply and demand, and the introduction of incentive policies, the economics of the battery energy storage technology featured long-life, low-cost, high-energy conversion efficiency are gradually highlighted. The application of energy storage technology has gradually shifted from demonstration to commercial operation. However, at present, the technical and economic performance of energy storage system is limited, and the economy of scale is not yet available. The capacity configuration and economic evaluation of energy storage system are prerequisites for the application of energy storage demonstration projects and commercial projects. By analyzing the energy storage application requirements and domestic policy environment, the necessity of energy storage capacity allocation and economic evaluation is proposed. The application functions, energy storage technology types and parameters of energy storage in all aspects of the power system, the current state of typical battery energy storage technology and the status of technical and economic indicators used in large-scale applications in power systems, and typical energy storage demonstration projects at home and abroad, the status of second-use of the retired power batteries in the power system and the status of the energy storage capacity allocation and economic evaluation, were analyzed and summarized.
