Extraction method for dispatching rules of the main reservoir considering joint operation risks in hydro-wind-solar power systems

Key Points

• The aim is to develop a method for dispatching rules in reservoirs while addressing risks in hydro-wind-solar systems.
• Constructed evaluation criteria for risk conditions considering multiple time scales using Monte Carlo simulation.
• Utilized K-means clustering to generate scenarios for extreme risk conditions to provide inputs for the model.
• Established a mixed integer linear programming model to optimize dispatching rules during specific periods.
• The proposed rules successfully reduced run risks, achieving zero water waste in flood periods and no power shortages in dry periods.
• The method effectively extracted reservoir scheduling rules across various parameter scenarios, ensuring operational stability for renewable energy integration.
