Evaluation method for open, fair and impartial dispatching power generation schedule

Abstract

The invention relates to an evaluation method for open, fair and impartial dispatching power generation schedule. The method comprises the following steps: 1) establishing an evaluation index system and an evaluation set of the power generation schedule, and obtaining evaluation index values of different schemes; 2) obtaining comprehensive weight vector according to the evaluation index system by utilizing an improved fuzzy analytical hierarchy process; 3) obtaining first fuzzy comprehensive evaluation result vectors of the different schemes according to the evaluation set and the evaluation index values by utilizing an isosceles triangle membership function; 4) obtaining second fuzzy comprehensive evaluation result vectors of the different schemes according to the evaluation set and the evaluation index values by utilizing a Gauss membership function; and 5) obtaining the optimum fuzzy comprehensive evaluation result vector of the different schemes by combining the first fuzzy comprehensive evaluation result vectors and the second fuzzy comprehensive evaluation result vectors based on vector similarity. Compared with the prior art, the method has the advantages of eliminating the difference between signal methods, and improving feasibility of evaluation result and the like.

Description

technical field [0001] The invention relates to the field of power system evaluation, in particular to an evaluation method for three public dispatching power generation plans. Background technique [0002] Three-public dispatching refers to strictly implementing the grid-connected dispatching agreement, following the objective laws of power system operation, and formulating dispatching plans under the premise of openness, fairness and justice. Three public dispatching is the most common dispatching mode in my country at present. The "three publics" are embodied in the following three aspects: 1) The signing of the annual contract of the power plant requires that the signing of the annual contract of each power plant be fair, that is, according to the national policy, the utilization hours of the same type of units are equal. In principle, an annual contract is signed; 2) Contract execution requires both the factory and the grid to strictly implement the signed contract. The ...

Problems solved by technology

[0006] The weight calculation method based on the analytic hierarchy process is very complicated when the number of indicators is large; the calculation method of the objective weight based on the entropy weight and the maximum entropy model is close to 1 when all the entropy values ​​are close to 1. There is a problem of inconsistency between the entropy weight and the information transmitted by the entropy value, which leads to errors in the evaluation results; the TOPSIS method needs to give positive and negative ideal solutions in advance, but most indicators have difficulties in the process of giving positive and negative ideal solutions; based on multiple membership degrees The evaluation method of the function combines multiple membership degree calculations, and the process is very cumbersome

Gaussian membership function evaluation method, in the process of giving the Gaussian membership function, does not take equal evaluation intervals, making the credibility of the evaluation results unconvincing
