Abstract :
This letter presents a control method for grid-connected PWM voltage source inverters (VSIs) featuring fast load voltage regulation and effective mitigation of fast voltage disturbances. The control scheme is based on a hybrid linear with variable-structure control (VSC) voltage controller and a deadbeat current regulator. The proposed scheme is applied to a VSI-based distributed generation (DG) interface to regulate the voltage at the point of common coupling (PCC).
