Research on Coordinated Control of DC Microgrid with Electric Vehicle
Due to the increasingly serious energy crisis and environmental pollution problem, the rapid development of electric vehicle technology is the main trend of the automotive industry in the future. With the increasing proportion of electric vehicles to conventional cars, the interaction technology of electric vehicles to microgrid has attracted wide attention. In order to solve this problem, a coordinated control strategy is proposed to achieve the interaction between the mobile energy storage of electric vehicles and the microgrid. The mathematical model of voltage source grid-connected converter, bidirectional DC/DC converter and photovoltaic power generation unit is established. The operation mode of the grid-connected operation and islanding operation mode are analyzed, and the control strategy of the different operation modes is given, the simulation model of the system is built through the Matlab/Simulink simulation software. Finally, the feasibility and effectiveness of the proposed method are verified by the simulation results.
