Distributed Control Method for Multi-User Side Energy Storage SOC Based on Consensus Algorithm

In recent years, user-side energy storage has developed rapidly and is widely used to save electricity costs for industrial and commercial users. Compared with source-side and grid-side centralised energy storage, user-side energy storage is more decentralised, with smaller single capacity and larger quantity, which is not easy to carry out centralised regulation and control. In contrast, the distributed control method has the characteristics of strong control robustness and stability, which is more suiTABLE as the SOC coordinated control of a large number of distributed energy storage. In this paper, a distributed energy storage SOC coordinated control algorithm based on improved consensus algorithm is designed, which can achieve SOC consensus control of multiple user-side energy storage, and compared with the centralised control scheme, it has the features of small computation amount of the central controller and strong robustness of the controller. Simulation results show that the distributed energy storage SOC coordinated control algorithm based on the improved consensus algorithm designed in this paper can effectively achieve the consistent control of multiple user-side energy storage in the station area.
