- Abstract
- In 2022, KEPCO implemented grid support functions for PV systems to prevent blackouts from voltage and frequency fluctuations during system failures. This includes Low Voltage Ride Through (LVRT), which poses concerns about fault currents affecting grid protection systems like Recloser and OCGR. Prior studies on PV integration fault analysis were limited to MW capacities and didn't cover malfunctions in grid support functions like LVRT. This paper analyzes grid flow with increasing PV capacity, using a PSCAD model of a smart inverter for simulating the LVRT function and conducting fault analysis. It focuses on the single line-to-ground fault (1LG), the most common in distribution systems, calculating fault current values, and recommends integration methods with existing protection systems by evaluating different capacity-based cases. © 2024 Korean Institute of Electrical Engineers.
