The Influence of Carbon Price on the Transmission Cost of UHV Power System

The carbon peaking and carbon neutrality goals in China will further promote the collecting of carbon emission tax. This change of carbon emission policy will have an important impact on the economy of UHV power system. Due to the carbon price influence the economy of different transmission lines, we construct a economic evaluation model of UHV power system including carbon price to analysis the cost of per kilowatt hour of transmission. This model is based on the life-cycle cost theory (LCC). From the aspects of cost and revenue, we construct the comparative evaluation models are adopted to evaluate the economy and cost per kilowatt hour of UHV power system. One model is considering the carbon emission quota and the other isn't consider the quota. These models providing theoretical basis for the planning and construction of UHV power system. Finally, we use case study to analyze electricity cost per kilowatt hour of UHV power transmission under different carbon prices. The case verified the influence of carbon price on the economics of UHV power system.
