Suppressive control of the resonance current between PV system and the power system

This paper proposes a new current control method that can keep high power factor and can suppress resonance current between photovoltaic power generation systems and the system that is generated when the system voltage changes suddenly. Resonance current suppression has been realized with state feedback control and with a prepositive compensator which frees the pole assignment. The ability of the original repetitive control is drawn by correcting the dead time, in the modified repetitive control.
