| description | The invention relates to an optimal dispatching method for a cascade hydropower station participating in a combined power market by considering dynamic water flow time lag, which takes power generation profit maximization of a hydropower enterprise participating in a medium and long term contract and a day-ahead spot combined power market as a target, and comprehensively considers dynamic water flow time lag between an upstream power station and a downstream power station, power station operation constraint, unit operation constraint and power constraint. And the refinement level of optimal scheduling of the cascade power stations is improved. A series of linearization processing methods are provided for nonlinear constraints in the model, such as a target function, a unit vibration area, dynamic water flow lag time between cascade power stations and a unit operation state, an original nonlinear mixed integer programming model is converted into a standard mixed integer linear programming model, and then the m |
