Orderly Charging Control of Distributed Electric Vehicles

Abstract

With the emergence of electric vehicle as an emerging industry, electric vehicle charging stations, electric vehicle supporting charging technologies and electric vehicle surrounding industries have also seen great development and changes. However, there are still problems such as difficulties in finding piles for electric vehicle users, low utilization rate of charging piles, and difficulty in making profits for operating enterprises. How can an electric car battery technology, the reasonable solution to charging pile enough information circulation and mutual trust between operators and electric car owners security issues, on this basis, considering a reasonable interest with the user of electric vehicle charging pile match, improve the utilization rate of resources, guarantee the user experience of charging at the same time, this is the need to study and solve the problem. Firstly, this topic proposes to establish an electric vehicle charging chain by using block chain technology, so as to reasonably solve the problem of insufficient circulation of charging pile information and mutual trust and safety between operators and electric vehicle owners. Secondly, in order to power grid security, user experience and the interests of the operators make a comprehensive consideration, assignment model is proposed based on distributed ordering of electric vehicle charging model will charge directly link between cars and charging pile, put forward considering ordering charging scheme of interests, and by solving the model to get the most reasonable ordering charging scheme. Thirdly, in order to better allocate the resources in the station, the waiting time of electric vehicle charging is reduced, and the orderly charging model is optimized. This topic proposes the power distribution strategy within the station, through a simple algorithm, to achieve the priority of using high power charging in the charging station with low power, and fully balance the load resources of each station. Finally, in order to verify the effectiveness of the model, the simulation platform is built and verified. Collected by charging and the electric car GPS data, set up the simulation object model by using ArcGIS software, and set up complete simulation platform of distributed electric vehicle charging ordering model for simulation, the simulation results show that the proposed ordering of electric vehicle charging model based on block chain technology can improve the utilization rate of resources, charging at the same time guarantee the user experience.
