Carbon Tracing Method for Regional Distribution Networks Considering Load Side Electricity Substitution
Electricity substitution is one of the main forms of energy transformation,which is significant for achieving the"dual carbon"goals by replacing the combustion of traditional fossil fuels with electricity.However,electricity substitution also generates carbon emissions in the power system.To clarify the carbon reduction benefits before and after electricity substitution,this paper proposes a regional carbon tracing method for load side electricity substitution in the distribution networks.Firstly,a precise carbon emission tracing model is established based on the iterative characteristic of carbon emission flow.Secondly,considering the carbon emission conversion mechanism of electricity substitution loads,carbon emission factors are adjusted to address the unfairness issue of carbon emission flow method allocating carbon emissions of electricity substitution loads to various nodes,thus constructing a load side electricity substitution model.Finally,the paper verifies the effectiveness of the method using a distribution network in the East China region as an example.The results indicate that this method provides a fairer assessment of carbon emissions from electricity substitution loads and offers scientifically accurate quantitative results for assessing carbon reduction indicators and the effectiveness of energy-saving technologies in regional distribution networks.
