Determination of Weights for the Integrated Energy System Assessment Index with Electrical Energy Substitution in the Dual Carbon Context

Electrical energy substitution is an important way to achieve the optimization of consumption structure as well alleviate environmental problems, and it also source benefits integrated system. However, there are few works that study effects electrical on construction system (IES) work without incentives carried out in IES. To this end, paper proposed a G1 method with constructing consistency matrix determine evaluation index weights for IES substitution. Specifically, we firstly construct including indicators, low-carbon technical indicators economic their secondary indicators. Then, tri-level target-criteria-indicator established based pertinent standards norms, taking practical operability into account. Finally, G1-method-constructed judgment proposed. Compared method, simple practical, weight calculation results more line reality, which effectively solves problem matrix. The rationality feasibility verified by analysis example.
