Abstract :
This paper put forward a repetitive control algorithm based on virtual resistance to the question that improving the gain characteristic of LCL filter circuit results in increased power lose. Apply the algorithm to embedded repetitive control system, and one new repetitive controller based on virtual resistance is formed, then use the controller to control the grid-connected part of PV system. Simulation results verified the correctness and feasibility of the algorithm.
