抗超高频噪声扰动的直流微电网协同控制方法
Coordination control method for DC microgrids against ultra-high frequency noise disturbances
摘要
Abstract
With the application of high-frequency chopping modulation technology,the ultra-high frequency noise interference in DC microgrids has become increasingly severe,and in extreme cases,it has already affected the stable operation of the system.To enhance the system's anti-interference capability and dynamic operation performance,a hierarchical collaborative anti-disturbance control method is proposed for DC microgrids with energy storage systems.A non-smooth composite control law is designed to mitigate the increasing ultra-high frequency noise disturbances through feedforward compensation.Based on a non-smooth dynamic average consensus protocol with low communication cost,a dynamic droop strategy is established to dynamically allocate power for State-of-Charge(SoC)balancing.The dynamic power allocation strategy and the primary control of each energy storage unit are utilized to ensure the dynamic balance of the SoC and the stability of the system-level bus voltage.Hardware-in-the-loop simulation results show that,compared with conventional strategies,the proposed strategy has stronger anti-interference capability and can be used for the stability of various energy storage supported microgrid systems.关键词
