摘 要

为了提高能源利用率、改善生态环境，可再生能源互补分布式供能系统已成为电力能源行业的研究热点。如何合理评价不同场景下可再生能源互补分布式供能系统是推进发展分布式供能系统首先需要考虑的问题。本文首先介绍了典型冷热电联供模式和可再生能源的互补方式，具体分析了典型并网型和离网型风光气储互补分布式供能系统和生光互补分布式供能系统中不同能源资源的互补机制，其次构建了考虑经济、技术、环保和社会因素在内的综合评价指标体系，研究了各类指标的科学计算方法，进一步综合考虑应用场景的差异性，基于改进的层次分析法（analytic hierarchy process, AHP)-熵权法来确定评价指标权重，运用直接评价法、TOPSIS（Technique for Order Preference by Similarity to an Ideal Solution）法、VIKOR法建立系统多准则评价模型。最后对并网应用场景下的可再生能源互补分布式供能系统进行算例仿真，仿真结果验证了本文提出的可再生能源互补分布式供能系统综合评价技术的正确性与合理性。

Abstract

In order to improve energy efficiency and improve the ecological environment, renewable energy complementary distributed energy supply systems have become a research hotspot in the power energy industry. How to reasonably evaluate the renewable energy complementary distributed energy supply system in different scenarios is the first problem to be considered in promoting the development of distributed energy supply systems. This dissertation first introduces typical modes of Combined Cooling, Heating and Power and analyzes the typical grid-connected and off-grid wind, light and gas storage complementary distributed energy supply system and the biomass energy and light energy complementary distributed energy supply system. Secondly, in the complementary mechanism of different energy resources, a comprehensive evaluation index system considering economic, technical, environmental protection and social factors was constructed. The scientific calculation methods of various indicators were studied. Considering the difference of application scenarios, the analytic hierarchy process (AHP)-entropy weight method is used to determine the weight of the evaluation index. The direct evaluation method, the TOPSIS (Technique for Order Preference by Similarity to an Ideal Solution) method and the VIKOR method are used to establish the system multi-criteria evaluation model. Finally, the simulation results of the renewable energy distributed energy supply system in the grid-connected application scenario are carried out. The simulation results verify the correctness and rationality of the comprehensive evaluation technology of the renewable energy complementary distributed energy supply system proposed in this dissertation.
