Abstract：The development of a novel energy supply and consumption system centered on ultra-high voltage(UHV)transmission and transformation project represents a critical strategy for enhancing the safety and resilience of China's emerging power infrastructure.Under increasingly stringent carbon emission policies,ultra-high voltage projects are proactively exploring the potential for green and low-carbon systems,aiming to drive carbon reduction throughout their entire lifecycle through the coordinated application of diverse green and low-carbon technologies.This study focuses on UHV transformation projects as a case study to establish a comprehensive evaluation framework that integrates the entropy weight TOPSIS method for objective assessment with questionnaire-based subjective evaluation.The framework is applied to analyze the technical feasibility of 40 advanced green and low-carbon technologies with potential for engineering application.Furthermore,the study accounts for complex variations in climate,geography,and resource endowments by conducting a multi-scenario assessment of technical adaptability.The findings reveal that,regarding feasibility,technologies such as recycled concrete and electric arc furnace steel during the material production and manufacturing phase;passive building envelopes,prefabricated units,during the construction phase;lithium-ion batteries and braking energy recovery systems in transportation;and photovoltaic power generation alongside intelligent ventilation systems during operation demonstrate superior performance across both objective and subjective metrics.These technologies are therefore recommended for prioritized implementation.Regarding scenario adaptability,waste heat power generation,absorption cooling,and intelligent ventilation systems can be implemented universally across all regions due to their high energy efficiency,stable operational performance,and resilience to climatic and resource variability.In contrast,climate-sensitive technologies—such as photovoltaic power generation,solar thermal power generation,wind power generation,and solar cooling—should be prioritized in areas with favorable resource endowments to optimize emission reduction outcomes and economic viability.This study provides decision-making support for the promotion and deployment of green and low-carbon technologies in ultra-high voltage transformation projects a research foundation for the integrated optimization of low-carbon,economic,and reliable performance throughout the project lifecycle.
