Abstract: With the ongoing transformation of the energy structure and the advancement of smart grid development, green and sustainable development of substations has become an inevitable trend. As the core driving force of substation transformation, novel technologies remain at the pilot application stage, and their performance evaluations are yet to be clarified. In view of this, this paper proposes a comprehensive evaluation framework for the application effectiveness of novel technologies in green construction for substations. Firstly, based on the feature for the whole life cycle of the technologies, an evaluation index system is established covering multiple dimensions and stages, including resource conservation, technical performance enhancement, and economic benefits. Secondly, on the basis of AHP group decision and EWM combination weights, a variable-weight model is constructed by combining projection gray target evaluation to enable significant differentiation in cross-technology comparative analysis. Finally, a case study is conducted on pilot applications of multiple novel technologies in substations within a specific region, and the results indicate that novel technologies which demonstrate better sustainable development effects throughout the entire life cycle have a broader prospect for promotion.
