A Path Analysis of Electric Heating Technology Based on Entropy Weight Method

As northern China to promote large-scale electric heating, at present there are mainly adopts centralized household electrical heating and decentralized household electric heating in two forms. However, in areas with different heat transmission facilities and different power grid access capabilities, how to reasonably determine the electrical heating technology path, ensure users satisfaction and optimize the investment level has gradually become a normalized problem. This paper investigates the existing typical demonstration projects of electric heating and the extended projects, summarizes the key technology characteristics of electric heating project and put forward comprehensive evaluation index system. On this basis, the advantages and disadvantages of different technical routes are measured based on entropy weight method, so that the appropriate technical routes can be given in different regional contexts. Finally, a practical case study verifies the effectiveness of the research results.
