Coordinated operation method of cascade hydropower stations considering runoff error

Journal of Physics: Conference Series, 2022
Abstract The traditional collaborative scheduling method of cascade hydropower stations group has the problem of imperfect regression model, which leads to excessive water consumption rate. A collaborative scheduling method of cascade hydropower stations group considering runoff error is designed. The influence factors of runoff forecast
