摘要：

Range-extender (RE) benefits to enlarge the driving mileage of electric vehicles; however, knowledge gap lies in the research of the V2G function of RE. To this end, this paper investigates the grid-connected generation and control strategies of RE. Firstly, a novel electrical position estimation algorithm was proposed based on the decoupling double synchronous reference frame phase-locked loop approach, and the Hall feedforward signal was incorporated to improve its response speed and estimation accuracy. On this basis, the grid phase-locked loop and voltage control were coordinated. Then, the multi-objective optimization was executed to optimize control variables to reduce the fuel consumption and unnecessary mechanical start-off. Besides, the start-off scheme and condition switch strategy were investigated in depth. Finally, a RE experimental platform with the engine, motor and generation devices was established to validate the electrical angle estimation algorithm, grid-connected generation strategy and condition regulation scheme. Results validate the executability and effectiveness of the proposed RE control strategy with V2G function. Copyright ©2022 Transaction of Beijing Institute of Technology. All rights reserved.
