Simultaneous planning method for distributed generation resources and electric vehicle charging stations considering carbon transaction costs

In order to actively respond to the relevant policies of the national carbon emission trading market, and change the traditional planning mode dominated by a single economic goal, this paper aims to explore the feasibility of the combination of carbon trading with electric vehicle charging station planning, and put forward a reasonable allocation scheme considering carbon trading cost. Aiming at the simultaneous planning scheme between distributed generation resources and electric vehicle charging station, the author first establishes a mathematical model to obtain the calculation result data of carbon emission, initial carbon emission limit and carbon transaction cost. Then, based on the analysis of the comprehensive investment cost calculation model of electric vehicle charging station, and considering the system power flow constraints and distributed power output constraints, this paper minimizes the carbon transaction cost and system investment as well as operation cost, a joint planning model of distributed generation resources and electric vehicle charging station considering economy and low carbon is constructed. Finally, a 33-node test system is given to verify the effectiveness of the method discussed in this paper. The conclusion of this paper is that the planning and carbon trading cost of electric vehicle charging station can effectively reduce the system carbon emission and improve the overall energy efficiency of the system.
