摘要：
Considering the structural uncertainty caused by the input or exit of the distributed generation unit in the DC microgrid, a robust H∞ method is used to design the controller to ensure the voltage stability. The regional pole configuration is used to constrain the controller parameters so that the poles of the closed-loop system fall in the region [D]. A robust H∞-γD controller is obtained based on the optimization solution of linear matrix inequalities. Its design only needs the DGU and the line parameters, but not the entire microgrid. Each DGU is configured with a controller embed in DGU to realize distributed control. Simulation shows that the robust H∞ control method has better robustness. © 2022, Solar Energy Periodical Office Co., Ltd. All right reserved.
