Method for deducing operation states and parameters of adjacent hydropower stations by using observation data

Abstract

The invention discloses a method for inferring operation states and parameters of adjacent hydropower stations by utilizing observation data, which comprises the following steps of: firstly, establishing a reverse inference double-layer optimization model for the adjacent hydropower stations according to historical data measured and disclosed by the hydropower stations; secondly, reconstructing the double-layer optimization model by using a regularization method to avoid multiple inference results; and finally, aiming at the fact that the lower-layer model has a large-range infeasible region, solving the reconstructed model by using an improved parallel genetic algorithm which has an infeasible region avoiding function and retains elite. According to the method, the operation state and the operation parameters of the target power station can be deduced well, and compared with a traditional method, the solving method has the advantages of searching an optimal solution, avoiding an infeasible region and increasing the solving speed. According to the method, a new technical approach is provided for the hydropower station to reversely deduce the operation state and the operation parameters of the adjacent power stations, and a technical reference is provided for the cascade hydropower station to adapt to a new power system operation mode under the dual-carbon target.
