Problems solved by technology

For the method of combining subjective weight and objective weight, there are only comprehensive weight calculation methods based on linear weighting and least squares method, but the linear weighting method cannot accurately give subjective and objective weight values, while the method based on least squares loses The physical meaning of subjective and objective weights

Embodiment

[0248] This embodiment uses the data of a power grid on April 9, 2014 under the three scheduling modes of the integrated day-ahead power generation plan, and uses the arithmetic mean value of the index values ​​corresponding to each time period in a day (96 time periods) to participate in the evaluation of the power generation plan.

[0249] Using the method of obtaining subjective weights based on the ordered binary comparison method, the obtained evaluation indicators are ranked by X * That is the order of the indicators listed in Table 1 (Table 1 gives the index values ​​of power generation plans under three different dispatching modes, among which the power generation plan corresponding to the three-public dispatching mode is Scheme 1, and the power generation plan corresponding to the economic dispatching mode is Scheme 1 2. The power generation plan corresponding to the energy-saving dispatch mode is scheme 3), and the obtained subjective weights are shown in Table 2. Fro...

Abstract

The invention relates to a power generation plan evaluation method based on a combination weight ELECTRE evaluation model. The method comprises the following steps: establishing a power generation plan evaluation indicator system, including security indicators, energy saving indicators, economic efficiency indicators and environmental indicators; calculating the subjective weight based on an ordered binary comparison method; calculating the objective weight based on a variation coefficient method; calculating the comprehensive weight based on vector similarity; and formulating an ELECTRE-based optimized decision scheme. By adopting the method, experience dependence caused by evaluation based on the subjective weight alone is overcome, and the credibility of evaluation results is ensured.

Description

technical field [0001] The invention relates to an evaluation method, in particular to an evaluation method for power generation plans based on a combined weight ELECTRE evaluation model. Background technique [0002] A scientific and reasonable power generation plan is the basis for realizing safe, economical and environmentally friendly operation of the power grid. There are obvious differences in the economy, safety and environmental protection obtained by the operation of power generation plans formulated according to different objectives. How to evaluate the relative advantages and disadvantages of power generation plans based on different objective functions, and select the power generation plan with the best comprehensive performance, has positive significance for improving the efficiency of power grid operation. [0003] The research on the evaluation of power generation plans can be roughly divided into two categories: 1) the definition and calculation of the index...
