An Electric Vehicles Charging Mechanism Based On Multi-agent System

With the development of the national economy, car ownership inChina is growing explosively, which brings opportunities and challengesat the same time. China tend to be more energy-intensive and its foreigndependence ratio of oil is affecting national energy security.Environmental stress appears gradually. Fog haze weather occursfrequently. China however says that its Copenhagen pledge to cut2005levels of carbon intensity by40to45percent before the end of thisdecade makes hydropower the best option. On the other hand, China’sautomobile industry is still in a big but not strong stage. The innovationdrive transition and development is the only choice to get moving.First of all, the paper builds a frame work to coordinate the benefitsof grid, charging station and vehicle owners. It distributes the duty andbenefit caused by electric vehicle charging behavior and using pricemechanism as the main control lever. Each side Coordinate to decide“When charging”,“How much electricity charge” and the charging powerto Realize charging behavior of the order. Then, we set up electric carconform to the model, the estimation of the electric vehicle charging loadsharing obligations to all charging station. Using the current motorvehicle driving behavior statistical data, combined with electric vehicleparameters, the establishment of electric vehicle charging load randomdistribution model is feasible. Each battery charging station to dailyoperation data as the basis, than model and modify the parameters, shouldbe able to get a better prediction results. Then, to formulate respectivelycharging station--power purchase price and charging station-electric carsales price. When formulating the purchase price，the grid evaluate andmake Rewards and punishments to the executive condition of loadforecasting to Encourage charging station take greater obligations and tosell more interests. On the other hand, charging station Use encouragemeans to Propose reasonable transport.The fifth chapter studies the orderly operation of the electric vehiclecharging station The traditional way is to set up optimization objective and constraint condition. This article will find another plan throughclassification. It divides charging stations into three types: stations forpublic transport, stations in communities and stations in companies.Through such division, we can Seize the main contradiction. The controlalgorithm is simple logical, easy for the owner to accept.
