摘　　要：随着新能源电动汽车的快速发展,充电设施的大规模接入电网对电网造成了巨大的冲击。在兼顾目前电网配电系统的同时解决电动汽车大功率充电需求问题,提出了一种基于功率前馈平衡控制策略的双向充放电系统方案。通过理论分析,搭建仿真模型,仿真结果验证了该方案的正确性及有效性。在上述基础上研发了一台样机,试验结果表明该方案有效解决了大功率充电对于电网的瞬时冲击,并可实现电网侧负荷峰谷调节作用。With the rapid development of new energy electric vehicles,the large-scale access to the grid of charging facilities has caused a huge impact on the power grid.In order to solve the problem of high-power charging demand of electric vehicles while taking into account the power distribution,a bidirectional charging and discharging system scheme based on power feedforward balance control strategy was proposed.The simulation model was built through theoretical analysis,the simulation results verify the correctness and effectiveness of the scheme.Based on the above,a prototype was developed.The test results show that the scheme effectively solves the instantaneous impact of high-power charging on the power grid,and also realize the peak-to-valley regulation of the grid side load.
