Distributed optimization model of shared energy storage participating in power grid auxiliary service based on ADMM

An interactive game optimization model of shared energy storage participating in the auxiliary service market of active distribution network and a distributed solution method based on alternating direction method of multipliers(ADMM) are proposed. The framework and interactive operation mode of shared energy storage participating in the auxiliary service market of active distribution network are designed. Considering the optimal operation objectives of active distribution network and the constraint conditions of shared energy storage equipment, an interactive game optimization model of active distribution network and shared energy storage is established. Based on ADMM, the global interactive game problem of the system is decomposed into distributed optimization problem, which is solved by distributed optimization. Taking the improve IEEE 33-bus system as an example for simulation, the results verify the rationality and effectiveness of the proposed interactive game optimization model and distributed solution method. It shows that the proposed method can take into account the economic and security requirements of active distribution network and achieve mutual benefit and win-win situation between active distribution network and shared energy storage users, while protecting the privacy of shared energy storage network and active distribution network.
