Strategy for Reactive Control in Symmetrical Low Voltage Ride through of Photovoltaic System

Abstract:

The active and reactive power decoupling control of photovoltaic system is analyzed in this paper. The DC-DC and DC-AC two level photovoltaic inverter model are built on the RTDS. A new type LVRT control strategy about photovoltaic system is proposed. In the symmetrical grid drop fault case, photovoltaic system output reactive power to support the grid voltage recovering and save reactive power equipment. The feasibility and effectiveness of the control strategy is verified by simulation and experiment on the RTDS.
