Enhanced Fault Ride-Through of Grid-Connected PV Systems Using PIR-MPC-Controlled Supercapacitor Energy Storage
Grid-connected solar photovoltaic (GSPV) systems experience prominent double-frequency oscillations in the DC-link voltage, real and reactive power during asymmetrical grid fault scenarios, which can severely affect low-voltage ride-through (LVRT) capability. This paper proposes a combined control strategy based on a...
