摘　　要：为提升充电设施利用率、拓展充电设施对电网辅助服务能力,直流充电设施支撑V2G,V2B,V2H等技术应用的需求日益明显。但由于其检测技术尚未开展系统研究,若套用现有检测技术不但沿袭了当前技术的不足,还舍弃了双向功率控制拓扑自身的优势。针对此问题,提出了多个双向功率型直流充电设施互为源荷的测试方法及其控制策略。以两个双向功率型直流充电设施为例,提出了背靠背互测的电路拓扑,并分析了其工作模式;引入模糊自适应PI控制提升动态响应能力;搭建了Matlab仿真模型和基于NI实时仿真器的实验平台,进行了验证。结果表明,所提测试方法和控制策略能有效地实现双向充电设施的测试,为相应产业提供了一定的参考依据。In order to increase the utilization rate of charging facilities and expand the ability of charging facilities to provide auxiliary services to the grid,the demand for DC charging facilities to support the application of V2 G,V2 B,V2 H and other technologies has become increasingly obvious. However,because its detection technology has not yet been systematically studied,if the existing detection technology is applied,not only the shortcomings of the current technology are followed,but the advantages of the bi-direction power control topology itself are abandoned. In response to these problems,a test method and control strategy for multiple bi-directional power DC charging facilities was proposed as the source and load of each other. Taking two bi-directional power DC charging facilities as an example,a back-to-back mutual test circuit topology was proposed and its working mode was analyzed. The fuzzy adaptive PI control was introduced to improve the dynamic response ability;the Matlab simulation model and the experimental platform based on the NI real-time simulator were built for verification. The results show that the proposed test method and control strategy can effectively realize the test of bi-directional charging facilities,which provide a certain reference for the corresponding industry.
