Embodiment Construction

[0064] The present invention will be further described below in conjunction with the accompanying drawings and examples of implementation.

[0065] For the actual hydropower station operating status and parameter estimation problem, for the convenience of description, the present invention names the three power stations in the case, which are respectively upstream power station, target power station, and downstream power station. For the detailed topology diagram, see figure 1 . Among them, the upstream power station and the downstream power station belong to the same property right subject A, and the target power station belongs to another property right subject B. The purpose of the present invention is to use the historical data of the upstream power station and the downstream power station under the property rights subject A, combined with the publicly released information of the target power station, to establish a reverse inference double-layer optimization model for the...

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.

Description

technical field [0001] The invention relates to the field of hydropower station operating status and operating parameter estimation, in particular to a method for inferring the operating status and parameters of adjacent hydropower stations by using observation data, and is a practical method for reversely inferring the operating status and operating parameters of adjacent hydropower stations by using observation data . Background technique [0002] Hydropower is a safe, economical, efficient, renewable, and dispatchable clean energy. It is also the clean energy with the largest installed capacity and annual power generation in China. It plays an important role in power supply, frequency regulation, and peak regulation in my country's power system. , ecology, shipping, etc. provide important guarantees. In terms of engineering, hydropower stations are often built along the river in the form of cascades, and water energy is utilized step by step from upstream to downstream, f...
