Low Voltage Ride-Through Capability Control for Single-Stage Inverter-Based Grid-Connected Photovoltaic Power Plant

Low Voltage Ride-Through Capability Control for Single-Stage Inverter-Based Grid-Connected Photovoltaic Power Plant

The low voltage ride-through (LVRT) capability is one of the challenges faced by the integration of large-scale photovoltaic (PV) power stations into electrical grid which has not been fully investigated. Therefore, this paper presents a comprehensive control strategy of single-stage PV power plant...
