A Comprehensive Evaluation Model of Power Market Operation Efficiency Based on Extension Cloud Theory
Energy Procedia(2019)
Abstract
Aiming at the fuzziness and randomness existed in the electric power market operation efficiency evaluation, and evaluation index selection in different regional electricity market such as subjectivity and uncertainty problems, put forward reasonable and effective method of electric power market operation efficiency evaluation. Firstly, on the basis of the electric power market operation efficiency level boundary information, the subjective weighting method of the analytic hierarchy process and the objective weighting method of entropy weight method are combined to integrate by additive integration to evaluate the comprehensive weight of all indexes of the operation efficiency of the power market. Secondly, the analysis method of the uncertainty of the cloud model is combined with the qualitative and quantitative analysis methods of the matter-element theory in the extension theory, and it establishes an evaluation model of power market operation efficiency based on extension cloud theory. On this basis, the credibility factor and risk factors are introduced to reflect the credibility and risk information of the assessment results. Finally, an example is given to verify the rationality and validity of this method.
