Large-Scale EV Integrated Multi-energy System Optimal Dispatch and Carbon Flow Analysis

Electric Vehicles have been increasingly integrated into the power system and would take a lager proportion of load in the future. This research examines the influences of the large-scale EV on multi-energy system in terms of cost, renewable energy accommodation and carbon emission reduction. The multi-energy system optimal operation dispatch model is proposed to dispatch the different energy conversion devices and energy storage devices considering EV integration. We establish the EV models considering the controlled charging scheme and V2G scheme into the dispatch model. The multi-energy system carbon emission flow theory is used to track carbon emissions and allocate the carbon emission on end-use energy including EV. The results show that the large-scale EV integration helps enhance system economic profits and effectively reduce carbon emissions.
