Abstract: At the beginning, this paper built a generator marginal output power incremental model according to the carbon emission characteristics of the clean energy source and traditional generation devices, geographical location of clean energy source, base load distributions and historical operation data. Then, a carbon emission model based on the scenario of out-of-order electric vehicles charging is built by taking the spatial and temporal driving and battery charging characteristics of electric vehicles into account. After that, in order to take more advantages of clean energy by reducing the marginal carbon emission increase from electric vehicle charging, a smart charging strategy between electric vehicles charging and renewable energy in carbon market is proposed in the model. Finally, carbon emission evaluation indexes are proposed in this paper on the basis of carbon cost calculation model. Results in the case studies show that, the proposed smart charging strategy could effectively reduce the carbon emission.
