Application Status and Economic Feasibility Analysis of Distributed Energy Storage Technology

The customer side energy storage is developing rapidly, which not only brings direct cost-saving benefits to power customers, but also indirectly benefits grid operation. This paper sorts out the relevant policies of customer side energy storage application, and investigates the application status of domestic and foreign customers' energy storage, and introduces the typical demonstration application cases of customer side energy storage in Jiangsu Province. Then, based on the life cycle cost-benefit present value method, the benefit model of the customer side battery energy storage in the whole power system is established, and explores the economic feasibility of customer side battery energy storage through case study. Finally, the market-scale energy storage of the customer side is predicted by combining the break-even point of the economic model.
