摘    要:针对大规模间歇性新能源并网造成的电力系统频率不稳定问题,提出利用电动汽车作为一种有效的需求侧响应资源,为电力系统提供辅助调频服务。在充分分析用户参与辅助调频服务受电价影响行为特征的基础上,提出了基于变参与度的电动汽车动态频率控制策略,可有效评估实时电价(real-time pricing,RTP)环境下电动汽车参与系统调频服务的响应能力。仿真结果表明:在RTP环境下,基于变参与度的电动汽车频率控制策略能够充分利用电动汽车负荷的充放电特性为电力系统提供动态辅助调频服务,有效支撑电力系统的动态频率稳定。

关 键 词:实时电价  电动汽车  变参与度  动态调频

Abstract:According to the problem of system frequency instability caused by large-scale intermittent renewable energy, electrical vehicle (EV) was used as valid demand response (DR) resource to provide ancillary load frequency control (LFC) service for power system. On the basis of the analysis on user’s behavior characteristics in ancillary LFC service impacted by electricity price, a dynamic LFC strategy with using variable participation factor was proposed for EVs, which could effectively evaluate the response ability of EVs in system frequency service under RTP (real-time pricing). The simulation results show that under RTP, the LFC strategy of EV based on variable participation factor can provide dynamic ancillary frequency modulation service for power system with using the charging and discharging characteristics of EV load, and effectively support the dynamic frequency stability of power system.
Keywords:   real-time pricing  electrical vehicle  variable participation factor  dynamic frequency modulation
