Suitable evaluation method of multi-energy complementary heating in villages and towns

Under the requirements of clean heating policy, multi-energy complementary heating in villages and towns has been developed rapidly, but there is a significant lag in the form of rational decision-making system and the accurate evaluation of application effect. In this paper, the existing evaluation methods are summarized from three aspects of index system construction, weighting, and comprehensive evaluation, in order to find the optimal evaluation method for multi-energy complementary heating in villages and towns, and apply it to case analysis. The results show that the evaluation method of using the analytic hierarchy process (AHP) method to determine the index system, the combination weighting method to determine the weight, the fuzzy comprehensive evaluation method to determine the system form, and the approximate ideal solution ranking method based on Euclidean distance and grey correlation degree to evaluate the application effect is more accurate than the current method.
