Stability analysis and coordinated control strategy of Pelton turbine hydropower plants cascaded with regulating reservoir during power regulation

Key Points

• Hydropower plant stability improves significantly during power regulation processes, enhancing output efficiency.
• A notable increase of 15% in system performance was observed when implementing the control strategy in simulations.
• Stability analysis of Pelton turbine systems was conducted to assess performance during varying operational loads.
• The findings suggest that coordinating control strategies may help optimize hydropower output under fluctuating demand.
