基于改进TOPSIS的乡镇综合能源系统效益综合评价方法

Comprehensive evaluation method for benefits of township integrated energy system based on improved TOPSIS

在以能源互联为主导的能源变革背景下,建设清洁高效的综合能源系统(IES)是助力乡镇实现可持续发展的重要环节。基于乡镇地区自然资源禀赋,提出一种计及风、光、地热和生物质能的可再生IES架构;针对城、乡能源系统在评价依据方面存在的差异,分别从经济、技术、运营、环保以及社会层面提炼出适用于乡镇IES效益评估的综合评价指标体系;引入结合了层次分析-决策实验室分析法和反熵权法的主客观指标赋权机制,并将其融入改进后的逼近理想解排序综合评价模型,从而实现乡镇IES效益的科学定量评估。最后,以江西省某乡镇综合能源系统示范工程为实施算例,验证了文中方法的合理性与有效性。

Under the background of energy revolution dominated by energy interconnection, the construction of clean and efficient integrated energy system(IES) is an important link to help township realize sustainable development. Based on the natural resource endowment of towns, this paper proposes a renewable IES framework which takes wind, light, geothermal and biomass energy into account. Aiming at the differences in the evaluation basis between urban and rural energy systems, the comprehensive evaluation index system suitable for the benefit evaluation of township IES is extracted from the economic, technological, ecological, service and social aspects respectively. The subjective and objective index weighting mechanism based on AHP-DEMATEL and anti-entropy weight method is integrated into the improved TOPSIS comprehensive evaluation model, so as to realize the scientific and quantitative evaluation of the benefit of township IES. Finally, the rationality and effectiveness of the proposed method are verified by taking a demonstration project of township IES in Jiangxi province as an example.
