摘要: 随着风力发电的快速发展,间歇性风电引起的电网功率波动问题日益凸显,而通过制定插入式电动汽车(plug-in electric vehicles, PEVs)的合理充放电策略,可为平衡功率波动和调节系统频率提供有效支撑。文章针对含风电的微网功率波动问题,提出了基于电动汽车参与意愿度和效用函数最大的PEVs协调运行模型,并基于一致性理论设计了PEVs分布式充放电控制方法。所提方法以完全分布式方式最优调整PEVs充放电功率,可有效平抑风电功率波动,并能满足PEVs日常多种充电场景需求,包括PEVs随机到达时间和启程时间、电池荷电状态随机初始值和目标值。最后通过含有5个风电场和2 000台PEVs的微网进行验证,仿真结果表明所提PEVs协调运行模型和分布式控制方法可灵活满足规模化PEVs的充放电需求,并可有效改善微网系统的频率响应特性。

Abstract: With the development of wind power generation, the problem of power fluctuation is increasingly prominent. The real-time reasonable controlling of plug-in electric vehicles (PEVs) can provide valuable ancillary service for balancing the active power and regulating the frequency of power systems. This paper proposed a coordinated PEV operation model based on the willingness to participation (WTP) parameter of charging patterns and maximal total utility of PEVs, in order to economically allocate PEVs' power for alleviating wind power fluctuations in a micro-grid. Furthermore, to solve this model, a consensus theory based center-free scheme is designed to control PEVs' charging/discharging power in real-time. The proposed scheme could flexibly satisfy PEV various charging scenarios including random arrival and departure time as well as the initial and desired State of Charge (SOC). Finally, the simulation is carried out in a micro-grid with 5 wind farms and 2 000 PEVs, and the simulation results show that the proposed coordinated operation model and distributed control method of PEVs can flexibly meet the daily flexible charging requirements of large-scale PEVs, and also effectively improve the frequency of micro-grids.

Key words: plug-in electric vehicles (PEVs), distributed control, coordinated operation model, frequency regulation, various charging scenarios
