Abstract

With the global energy transition and advancing low-carbon goals, wind power has emerged as a crucial clean renewable energy source, where large-scale grid integration has become a core trend in energy development. However, weak grid conditions significantly increase voltage stability risks during wind power integration. Insufficient reactive power support during faults may trigger protection trips, power generation restrictions, wind curtailment, cascading instability, and economic losses. To address this challenge, this paper proposed an integrated control solution for grid-connected wind farms that balances constraints and collaborative capabilities among turbines, substations, and energy storage systems. Specifically, PMSG units implement "fixed current switching" on the grid-side converter to prioritize reactive power injection for voltage recovery at the point of common coupling (PCC). The grid-side layer adopts STATCOM with dual PI controllers (DC V/Var outer loop and current inner loop), enhanced by repeated control (RC) to improve current tracking of periodic disturbances. The energy storage system employs supercapacitors for multi-level reactive power support based on voltage status, coordinating STATCOM switching through adaptive thresholds. Short-circuit and power step simulations using a high-fidelity PSCAD model demonstrate that this strategy significantly accelerates PCC voltage recovery, suppresses power oscillations, and enhances fault ride-through capability, meeting LVRT requirements while providing a viable pathway for wind power integration and operational resilience in weak grids.
