Evaluation System and Method for Carbon Emission Indicators of Electricity Users
This paper constructs a monitoring indicator system of carbon emissions for electricity users,addressing the current lack of comprehensive evaluation of carbon emissions from electricity users.Firstly,this paper provides an overview and summary of existing methods for calculating carbon emissions for electricity,based on power flow tracking methods,and determines the method for calculating carbon flow from the power system source side,transmission side,and distribution side.Secondly,based on factor analysis and the characteristics of the power system,the composition and influence of the indicator system are considered from the three major aspects of energy,economy,and the power grid.Then,based on the energy,economic,and power grid criteria layers,eight carbon emission evaluation indicators and the calculation methods are defined,thus forming a comprehensive monitoring indicator system for carbon emissions for electricity users,and establishing a comprehensive evaluation model based on the analytic hierarchy process.Finally,in combination with the data from IEEE 33 standard distribution network nodes and users,calculations and analysis are conducted,demonstrating the effectiveness of the model and methods presented in this paper.
