[Abstract]:V2G system is a new system developed with the rapid development of vehicle networking technology, the contradiction between the rapid growth of user demand and limited energy sources, and the increasingly significant market occupancy ratio of electric vehicles. In this paper, the information transmission strategy of V2G system is taken as the core problem. V2G information transmission mainly includes two core research contents. On the one hand, V 2 G message transmission mode is responsible for V 2 G communication system. On the other hand, the V2G traffic information in the data packets transmitted by the V2G communication system is related to the assignment indication of the resource scheduling algorithm. In this paper, a communication architecture of V2G system based on aggregator is proposed. The communication architecture is a heterogeneous network fusion architecture considering the type of V2G services. It can effectively use the existing communication network technology to serve V2G system. Then, this paper designs a resource scheduling algorithm which can work with the communication architecture. Based on the mobile mode of the vehicle, the proposed algorithm can further consider the user behavior and achieve the optimal charging scheduling under the premise of maximizing the user satisfaction. The V2G communication system is a heterogeneous wireless network system. Vertical handoff decision is the key feature of the heterogeneous wireless network system. In this paper, a vertical handoff algorithm is proposed to promote load balancing in different wireless network systems on the basis of considering user services in heterogeneous wireless networks. This algorithm defines the concept of vertical handoff tendency value, and makes dynamic switching decision for vehicles that meet vertical handover tendency value below vertical handover threshold to maximize load balancing. The concept of V2G which has just been put forward in recent years is still in the research and experimental stage, and the V2G system experimental platform plays an important role in promoting the V2G research. In this paper, we first design a delay test experiment, which is designed to test the end-to-end delay in different network environments by designing a delay test based on Android. Then, this paper designs the V2G simulation platform protocol stack based on NS3, and realizes all module functions of communication layer in the protocol stack. Finally, the validity and practicability of the platform are verified by the experimental data, and the resource scheduling algorithm and the vertical switching algorithm are simulated based on the simulation platform.
