【摘要】：电能替代战略是我国提升环境质量与电气化水平的必由之路。根据电能替代的影响要素和基本属性,构建了基于环保性、经济性、政策性、技术替代性的电能替代综合评价指标体系,并且提出一种对多层次灰色关联分析和网络层次分析进行信息熵融合的评价方法(MGRA-ANP:信息熵融合多层次灰色关联分析法)。采用该方法对北京地区电能替代影响因素进行综合评估,并与2种常规评价方法进行对比,验证了该方法在电能替代综合评估中的有效性和准确性。北京地区的实际算例分析表明,该方法得出的评估结果有效反映了北京地区电能替代的发展状况和薄弱环节,为电能替代实施提供更为全面、科学、精确的决策依据。
[Abstract]:Electric power substitution strategy is the only way to improve environmental quality and electrification level in China.According to the influence factors and basic attributes of electric energy substitution, a comprehensive evaluation index system of electric energy substitution based on environmental protection, economy, policy and technology substitution is constructed.An evaluation method of information entropy fusion for multi-level grey correlation analysis and network hierarchy analysis is proposed. MGRA-ANPA: Multi-level grey relational analysis method for information entropy fusion is proposed.This method is used to evaluate the influence factors of electric power substitution in Beijing area, and compared with two conventional evaluation methods. The validity and accuracy of this method in the comprehensive evaluation of power substitution are verified.The analysis of practical examples in Beijing shows that the evaluation results obtained by this method can effectively reflect the development and weakness of electric power substitution in Beijing, and provide a more comprehensive, scientific and accurate decision basis for the implementation of electric power substitution.
