Real-time feedback based multi-period trend optimization method of cascade water-power water level control

The invention discloses a real-time feedback based multi-period trend optimization method of cascade water-power water level control. The method comprises the following steps that 1) basic data is collected; 2) whether the cascade water-power water level satisfies requirements is determined; 3) operation control of cascaded water power is modeled; 4) operation constraints of the power grid are modeled; 5) operation constraints of a thermal power fire coal set are modeled; and 6) a multi-period optimal trend is modeled. The method based on real-time monitoring of the cascade water-power water level control is used to track water level change of a reservoir in real time, a multi-period optimal trend control method in which the water level of the reservoir is coordinated with operation of thepower grid is constructed on such basis, complex nonlinear conditions are processed linearly on the basis of real-time feedback, and the operation efficiency of cascade water power is improved greatly. 本发明公开了种基于实时反馈的梯级水电水位控制
