| description | Large-scale centralized photovoltaic power plants (PVPPs) connected to a power grid may cause short-term voltage instabilities during fault ride-through (FRT) processes. However, analyzing and optimizing short-term voltage characteristics requires extensive time-consuming simulations due to complex dynamic interactions between the grid voltage and FRT behaviors of PVPPs. To solve this problem, an analytical simulation-free method is proposed in this paper. Firstly, the coupling between the grid voltage and the PVPP’s FRT behaviors is formulated as a real-time varying impedance. Then, a fast analytical method is proposed to derive the grid short-term voltage dynamic trajectories during the complete FRT processes, and the non-monotonic impact of the PVPP’s FRT parameters on short-term voltage stabilities is demonstrated. Further, a selection method for the PVPP’s FRT parameters is proposed and verified using a regional grid. The proposed method improves the grid’s short-term voltage stability with small computational burdens. |
