区域级综合能源系统多维度能效评估方法研究

Research on Multi-dimensional Energy Efficiency Assessment Method of Regional Integrated Energy System

随着全球能源与环境问题日益突出,具有多能互补特性的区域级综合能源系统(RIES)是一种有效的解决方法。为了实现区域级综合能源系统能效的全方位、合理评估,从能源供应效率、能源转换效率、能源供应可靠性、能源供应质量、经济效益与社会效益等六个维度对其进行了详细的指标体系构建,并在AHP-熵权法的基础上给出了组合权重计算方法,进而提出了更加直观、清晰地对不同规划方案进行评估的基于改进TOPSIS法的区域级综合能源系统能效评估方法;最后,通过区域级综合能源系统的算例验证了所提方法理论的合理性与有效性。

With the global energy and environmental problems becoming increasingly prominent,the regional integrated energy system(RIES)with multi-energy complementary characteristics is an effective solution. In order to realize the comprehensive and reasonable evaluation of energy efficiency of the RIES,a detailed evaluation index system from the aspects of energy supply efficiency,energy conversion efficiency,energy supply reliability,energy supply quality,economic and social benefits was established. And on the basis of AHP entropy weight method,the calculation method of combination weight was given. Then,a regional integrated energy system energy efficiency evaluation method based on improved TOPSIS was proposed to evaluate different planning schemes more intuitively and clearly. Finally,the rationality and effectiveness of the proposed method were verified by an example of a RIES.
