摘要
A system for modulating a current level of a power grid includes a perturbation module that injects a sinusoidal signal, at a cross-over frequency, to modulate a duty cycle to a power converter connected to the power grid; a current controller that monitors a reference current and a current at grid-side terminal of the power converter, the current controller further monitors a current of the power grid; and a parameter calculation module that calculates a plurality of gain values for the current controller based at least in part on a phase margin, a cross-over frequency, a current of an alternating current side of the power converter, and the duty cycle.
