摘要：

Utilizing battery energy storage system is considered to be a reliable approach to improve the stability of modern power grid. By properly controlling the battery energy storage system, the redundant power can be absorbed and the lack of power can be supplemented. The control strategy of power conversion system directly affects the performance of battery energy storage system. Therefore, an improved active disturbance rejection control algorithm for power conversion system with LCL filter is presented in this paper. First of all, a pole placement strategy based on full state feedback is implemented in order to solve the resonance problem of LCL filter. Secondly, the total internal and external disturbances of power conversion system are compensated on basis of a linear extended state observer for purpose of improving the system robustness against inevitable interferences and parameter uncertainty. Furthermore, the stability of presented control strategy is analyzed and discussed in detail. Finally, the simulation and experimental results extracted based on a 2.6 kVA prototype are both provided, which can confirm the feasibility and correctness of the control strategy.
