One-dimensional linear approximate processing method for hydropower output

The invention discloses a one-dimensional linear approximate processing method for hydropower output. The method comprises the following steps: firstly, representing a hydropower output relation as a binary function of a water head and power generation reference flow, constructing a P-q-H three-dimensional coordinate system, taking NH + 1 coordinate points on an H axis, taking a central point of an mth interval [Hm, Hm + 1] as a representation of the interval, obtaining NH unary functions, performing linear segmentation processing on each given unary function according to segmentation points, and obtaining a final result; according to the method, the binary inseparable nonlinear hydroelectric output relation is approximately processed into the linear relation, the precision and the efficiency are both considered, and the optimal hydroelectric output process is obtained. The method can be used for developing and deploying a reservoir power generation scheduling model or a hydropower-related power system optimi
