Short-term forecasting-based optimal scheduling of a pumped storage hydropower, wind, and photovoltaic complementary system

IntroductionAs clean energy penetration grows, short-term coordination of pumped storage hydropower plants (PSHPs), wind power and photovoltaic (PV) generation is increasingly important for secure and economical dispatch under renewable variability.MethodsThis study proposes a short-term forecasting-based scheduling and benefit allocation method for a PSHP-wind-PV complementary system. A hierarchical prediction and dynamic correction (HPDC) strategy improves 24-h forecasts of wind power, PV powe
