Abstract:
In recent years, countries worldwide have intensified efforts to adopt renewable energy. China, in particular, has integrated a substantial amount of wind and photovoltaic (PV) output power into its grid. By the end of 2024, the total installed capacity of wind and solar power in China accounted for over 40% of the nation’s total power capacity, reaching approximately 1.35 billion kilowatts. However, the inherent output fluctuations of wind and solar energy present significant challenges to grid safety and stability. Pumped storage power stations have emerged as one of the most effective solutions to support grid reliability. In grids with high renewable energy penetration, the demand for rapid adjustment capabilities from pumped storage units has surged. This necessitates not only faster transitions between operational conditions but also robust safeguards for unit safety and stability.
