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.

Evaluates dispatching rules for hydro-wind-solar systems, suggesting improved operation stability.
