Unit power regulation parameter weight determination method and device

Abstract

The invention provides a unit power regulation parameter weight determination method and device. The method comprises the following steps: acquiring assessment index data of a unit power regulation parameter; processing the assessment index data by using an analytic hierarchy process to determine a subjective index weight; processing the assessment index data by using a variance weighting method to determine a variance weight; processing the assessment index data by using a CRITIC method so as to determine a CRITIC weight; and processing the determined subjective index weight, variance weight and CRITIC weight by using a minimum information identification method to generate a combined weight as a unit power regulation parameter weight determination result. A subjective weighting method and an objective weighting method are combined, the defects of subjective weighting and objective weighting are effectively avoided, subjective experience and the variation degree and conflict of objective data of indexes are fully considered in the combined weight, and compared with a traditional method, the method is more accurate, and the accuracy of a result is improved.

Description

technical field [0001] The invention relates to electric power technology, in particular to a method and device for determining the weight of unit power adjustment parameters. Background technique [0002] Large-scale grid-connection of new energy sources not only relieves energy shortages and environmental pollution, but also poses a huge challenge to the stable operation of the power system. The development of energy storage technology is an effective solution to solve the problem of large-scale new energy grid connection. The pumped storage power station is recognized as a flexible and reliable peak-shaving power source in the world. The pumped storage power stations that have been put into operation at home and abroad have brought good economic benefits to the power system. The pumped storage power station has the characteristics of flexible and reliable operation and rapid switching of working conditions. On the one hand, it can ensure the stable operation of power gri...

Problems solved by technology

[0004] In the prior art, most of the studies on the evaluation of pumped storage regulation ability start from the aspect of economic benefits, but there are few studies on the quantitative evaluation of the power regulation ability of the unit itself and the power station in the flexible DC grid. Among the existing evaluation methods, most The subjective assignment of index weights by using the AHP method is greatly disturbed by subjective factors, and the assignment results may deviate greatly from the actual ones
