Reconfiguration of the electric vehicle integrated distribution system considering carbon-reduction benefit

The extensive use of electric vehicles (EVs) can reduce carbon emission. However, when electric vehicles are getting plugged into the grid on a large scale, it will bring power fluctuations to the grid and affect its stable operation. In order to ensure the smooth, economic and low-carbon operation of the distribution network, this paper proposes a reconfiguration method of the electric vehicle integrated distribution system with consideration of carbon-reduction benefits. The proposed model takes the factors that affect the comprehensive cost of the distribution network into accounts, such as network losses cost and system carbon emission cost, and realizes the optimal dispatch of power resources. To verify the effectiveness of the model, this paper uses the IEEE 33-node distribution system connected to electric vehicle charging stations as an example, and uses MATLAB to conduct simulations. The simulation result shows that the established optimization model can effectively cut down the comprehensive cost of distribution system.
