Abstract
This paper proposes the active power modulation control scheme of the hybrid photovoltaic (PV) generator and battery for power swing stabilization. The battery which is connected to the DC link of the PV generator, is used to smooth the output power fluctuation of the PV generator during normal operation. During faults, the stored energy of battery can be used for the active power output modulation control of the PV generator to stabilize the power swing. By equipping the power oscillation damper (POD) at the active power controller of the PV inverter, the active power output can be modulated to damp the power swing. The POD structure is a practical second-order lead/lag compensator with single input signal. Simulation study confirms the stabilizing effect of the PV with POD.
