Driven by the goals of carbon neutrality and carbon peaking

the low-carbon construction in operator regions has an important impetus to promote the development of the power system and even the low-carbon economy in the whole society. The advantage of comprehensive evaluation of the low-carbon level of the operator regions can not only enable the power grid enterprises to have an objective judgment on the current low-carbon development level in the operator regions

and also can provide a direction and decision for the low-carbon management on the demand side. A comprehensive multi-objective operator region low-carbon index system is constructed

which includes the external network

the network loss

the internal network and the source network load and storage. A new index weight determination method is proposed based on the combination of entropy-independence weights

while vlsekriterijumska optimizacija I kompromisno resenje method and the matter-element extension model are combined in order to solve the decision-making problem of multi-attribute and multi-subject classes

so as to realize the overall assessment ranking and local feature analysis of different types of operator regions. Using 15 different types of operator regions in Shanxi as the research object

an example analysis is carried out to verify the scientific

practicability and effectiveness of the proposed evaluation system.
