Electric power replacement technology comprehensive benefit assessment method based on comprehensive weighting method

Abstract

The invention provides an electric power replacement technology comprehensive benefit assessment method based on a comprehensive weighting method. The method comprises the following steps: 1) constructing an electric power replacement technology comprehensive benefit assessment index system architecture; 2) calculating objective weights of four-level index layers in the system architecture according to an entropy theory; 3) calculating each factor weight vector of second-level rule layers, three-level index layers and the four-level index layers in the system architecture; 4) calculating comprehensive weights of elements in the four-level index layers in the system architecture; and 5) carrying out analysis evaluation on the system architecture. Various factors influencing electric power replacement technology comprehensive benefits are taken into overall consideration in the technical performance aspect, environmental effect aspect, economic benefit aspect, power grid operation aspect, thereby maximizing the comprehensive benefits introduced by the electric power replacement technology.

Description

technical field [0001] The invention relates to a method for evaluating comprehensive benefits, in particular to a method for evaluating comprehensive benefits of electric energy substitution technology based on a comprehensive weighting method. Background technique [0002] Research results and operating experience at home and abroad show that energy emissions, environmental pollution and climate deterioration have become serious problems affecting people's lives. Statistics show that the nitrogen oxides, sulfur dioxide, and smoke emissions from coal combustion in my country account for about 56%, 86%, and 74% of the national total, respectively, and the PM2.5 produced accounts for 50% to 60% of the total. The emission of soot from direct combustion of coal is nearly three times that of the equivalent amount of thermal coal, and the consumption of petrochemicals has resulted in the long-term emission of large quantities of pollutants. In view of the fact that the developme...

Problems solved by technology

[0003] Although there have been some studies on the evaluation of electric energy substitution technology using comprehensive evaluation methods and theories, a complete and scientific evaluation method and index system have not been formed to evaluate the comprehensive benefits of electric energy substitution technology.

There are many factors that affect the comprehensive benefits of electric energy substitution technology. These factors have the characteristics of mutual influence and interdependence, so it is difficult to measure and define
