Research on Electricity Market Transaction Based on Multi-Agent Shared Energy Storage

Shared energy storage is widely concerned because it can improve the utilization rate of energy storage and reduce the total cost. With the support of policies, shared energy storage has gradually developed, but its immature operation mode has hindered the further development of shared energy storage. Unreasonable service pricing may lead to the uneven income of each shared energy storage power station and each user and the poor benefits of each subject. In this paper, the user-side shared energy storage is studied, and the operation control of shared energy storage based on multi-agent is studied. With the goal of minimizing the total cost, a shared energy storage power station-user-operator operation control model is established. The total cost includes shared energy storage power station investment cost, shared energy storage power station operation cost, user operation cost and operator operation cost, and the charging and discharging behavior of shared energy storage power station, user charging and discharging behavior and operator charging and discharging behavior are obtained, and the investment cost, shared energy storage power station operation cost, user operation cost and operator operation cost are obtained. The influence degree of some uncertain factors on the total cost is obtained through sensitivity analysis.
