Abstract
This paper studies the impact of dynamic voltage support and active power recovery rate in a grid-connected large-scale Photovoltaic (PV) generator on Power Swing Blocking (PSB) protection used to detect Stable Power Swings (SPS). The reactive power priority (Q-priority) mode is considered during Low Voltage Ride-Through (LVRT)/High Voltage Ride-Through (HVRT). The dynamic voltage support is implemented using K-factor. The K-factor is varied to observe its impact on the power swing impedance trajectories and magnitude of the rate of change of positive-sequence impedance (|dZ/dt|). The impact of active power recovery rate during fault recovery on power swing trajectories and |dZ/dt| are also presented. The modified IEEE-39 bus system with a Synchronous Generator (SG) replaced by a Grid-Following (GFOL) PV generator is utilized for the studies. The PV has LVRT/HVRT capabilities and complies with IEEE Standard 2800-2022. The different test cases studied are simulated using PSCAD software. © 2024 IEEE.
