基于改进共原点灰色聚类的清洁能源消纳综合效益评估

Comprehensive Benefit Evaluation of Clean Energy Consumption Based on Improved Common Origin Gray Clustering Evaluation Method

考虑清洁能源消纳带来的经济、社会和环境效益,为清洁能源项目规划提供指导,建立合理的评估指标体系,结合基于混合交叉赋权和改进共原点灰色聚类的方法,对清洁能源消纳综合效益进行评估。该方法通过指标的变异系数,来确定以相邻指标的重要性程度之比代替序关系法中的方法,构造基于变异系数序关系法的混合交叉赋权方法,有效避免序关系法或变异系数法单独确定权重无法反映实际数据客观信息或决策者主观意图的弊端。同时,针对共原点聚类函数的灰类交叉以及隶属度等速率变化的不准确性,修改共原点灰色聚类的函数区间和函数形式,使得评估结果更具合理性和真实性。

Considering the economic,social and environmental benefits of clean energy consumption,and aiming at providing guidance for clean energy planning,this paper establishes a reasonable evaluation index system,and evaluates the comprehensive benefit by combining the mixed-cross weighting and the improved common origin gray clustering evaluation method.This method uses the variable coefficients of the indexes to determine the ratio of importance degree of adjacent indexes,instead of the order relation method.It constructs the mixed-cross weighting method based on the variable coefficient and order relation method,which can effectively avoid the disadvantage that the order relation method or the variable coefficient method cannot reflect the objective data information or the subjective intention of decision-making.In view of the inaccuracy of the rate change of gray-crossing and membership degree of the common origin gray clustering function,the function interval and form of the common origin gray clustering are modified to make the evaluation results more reasonable and authentic.
