中文摘要:

      随着传统化石能源枯竭、能源需求增加、使用效率低和生产不可持续，传统能源已经显示出许多不足。多能源供给系统的引入能够提高能源综合利用效率，推进可再生能源的发展，使得供电可靠性增强，满足不同应用场景的需求。为此，针对区域多能源供给系统的技术经济综合评估指标体系和方法展开研究。首先，构建并分析了典型的区域多能源供给系统结构特征；其次，从能效性、经济性和环保性等方面构建了区域多能源供给系统的综合评估指标体系；然后，采用DEMATELANP反熵权组合方法和改进灰色关联度法分别确定准则层和指标层各评估因素的权重，采用多项式差值法构析区域多能源供给系统指标评分函数；最后，对运行于江苏某居民区的区域多能源供给系统进行实证评估，研究结果验证了所构建评估指标体系和所提评估方法的可行性和有效性。

英文摘要:

      With the exhaustion of traditional fossil energy and the increase of energy demand, low efficiency and unsustain able production, traditional energy has shown many shortcomings.The introduction of multienergy supply system can improve the comprehensive utilization efficiency, promote the development of renewable energy, enhance the reliability of power supply, and meet the needs of special places. In this paper, the comprehensive evaluation index system and method of regional multienergy supply system are studied. Firstly, the typical regional multienergy supply system structure is constructed. Secondly, the comprehensive evaluation index system of regional multienergy supply system is constructed from the aspects of energy efficiency, economy and environ mental protection. Then, DEMATELANPAnti Entropy combinatorial method and the improved grey correlation method are respectively used to determine the weights of each evaluation factor in criterion layer and indictor layer, and the polynomial interpolation method is used to construct the index scoring function of regional multienergy supply system. Finally, a comprehensive evaluation of the regional multienergy supply system in a residential area of Jiangsu province is carried out, and the research results verify the feasibility and effectiveness of the proposed evaluation index system and evaluation methodk.
