To systematically investigate the impacts of wind and solar power integration on medium-to-long-term optimal scheduling of the Qingjiang cascade hydropower stations, a multi-objective optimization model for coordinated hydro-wind-solar operation was established. The objective function was reconstructed through objective transformation integrated with penalty mechanisms and solved using the progressive optimization algorithm (POA). Case studies demonstrate that the model simultaneously ensures system power generation while achieving complementary coordination between cascade station operations and renewable power output. Through analysis of complementary coordination effects and reservoir level variations, operational pattern modifications for the Qingjiang cascade reservoirs were extracted: following renewable integration, storage/discharge strategies should be prioritized for adjustment during wet/normal years based on inflow characteristics. This adaptation reserves additional storage capacity to flexibly accommodate complementary coordination requirements with renewables while fulfilling power generation demands.
