中文摘要:
      随着物联网技术与新一代移动通信技术的快速发展,电动汽车与配电系统间的交互由单一时间维度扩展为时间-空间多维度协同,显著影响新型配电系统的供电可靠性。基于这一背景,分析了大规模电动汽车集群化管理策略,揭示了配电系统中电动汽车时空可调度特性的数学表征方法,提出了计及电动汽车时空可调度特性的配电系统可靠性评估方法。为验证所提出方法的有效性,基于改进后的IEEE-RBTSBUS6的主馈线F4系统,对计及时空可调度特性电动汽车接入前、接入后及电动汽车不同放电能力下的配电系统可靠性进行了相应的计算分析,揭示了新形势下电动汽车接入对配电网供电可靠性的影响规律,可为电动汽车接入下配电系统的可靠性提升提供有效的理论支撑。
英文摘要:
      With the rapid development of Internet of Things technology and the new generation of mobile communication technology, the interaction between electric vehicles and distribution systems has expanded from a single time dimension to time-space multi-dimensional coordination, which significantly affects the power supply reliability of the new power distribution system. Based on this background, the cluster management strategy of large- scale electric vehicles is analyzed, the mathematical representation method of the temporal and spatial schedulable characteristics of electric vehicles in the distribution system is revealed, and the reliability of the distribution system that considers the temporal and spatial schedulable characteristics of electric vehicles assessment method is proposed. In order to verify the effectiveness of the proposed method, based on the improved IEEE-RBTS BUS6 main feeder F4 system, corresponding calculation and analysis are carried out on the reliability of the distribution system considering the time-space schedulable characteristics of electric vehicles before and after the connection and under different discharge capacities of electric vehicles. The calculation and analysis reveal the influence of electric vehicle access on the power supply reliability of the distribution network under the new situation, which can provide effective theoretical support for the reliability improvement of the power distribution system under the electric vehicle access.
