[Abstract]:Electric vehicles (EVs), as an important way to accelerate energy transformation and realize low-carbon economy, has attracted more and more attention in more and more countries. The electrification of vehicles is an inevitable trend in the future. The problem of electric vehicle charging has been one of the key problems restricting the development of electric vehicle. The new energy generation and electric vehicle wireless charging are integrated into the microgrid. The research on wireless charging control strategy for electric vehicles will effectively promote the popularity of electric vehicles and increase the absorptive capacity of new energy sources. In this paper, the combination of microgrid technology and radio energy transmission technology is adopted. The layered control strategy of wind and wind complementary microgrid is studied to realize the reliable charging of electric vehicle, and a new idea of charging mode of electric vehicle is provided. The photovoltaic, wind power and battery are used to form independent wind complementary micro-grid. By analyzing the relationship between the sum of the maximum output power and the load power of photovoltaic and wind power, the possible operating state of the system is obtained. The upper central controller and the bottom controller are designed. The upper central controller is responsible for the selection of the system operation state, the switch and the management of the bottom controller. The bottom controller includes wind power maximum power output controller, battery charge and discharge controller, DC bus terminal voltage controller of high frequency inverter side and on-board battery charging controller. By optimizing the parameters of inductance and capacitance at the transmitter and receiver, the system is in the resonant state and the optimal energy transfer efficiency is achieved when the rated power is running. On this basis, in order to realize the on-board battery access with different capacity, The DC bus of the transmitter adopts the constant voltage control strategy, and the voltage reference value is adjusted adaptively according to the different charging power of the on-board battery. Simulation and experimental results show that the hierarchical control strategy can ensure that when the illumination, wind speed changes and the number and power of the electric vehicle access changes, The scheme can effectively solve the impact of electric vehicle charging on the grid and improve the flexibility of charging.
