【摘要】：目前对电动汽车参与电力系统调频的研究,主要集中在电动汽车作为分布式电源参与系统调频,而对电动汽车作为可控负荷参与系统调频的研究较少。但是,电动汽车作为分布式电源和可控负荷对其参与系统调频具有同等重要的作用。基于此,文中计及了电动汽车的充放电静态频率特性模型,在电力系统负荷扰动发生时,实现了对电动汽车充放电的协调控制,使其在分布式电源和可控负荷两个角色间合理转换。在此基础上,建立了计及电动汽车充放电的单区域系统负荷频率控制模型,并将该模型扩展为两区域互联系统。在MATLAB/Simulink中建模并进行仿真分析。算例结果表明,电动汽车作为分布式电源和可控负荷参与系统调频,不仅可以使系统频率调整速度更快,有效减小系统频率偏差,而且能减小传统调频机组的备用容量。
[Abstract]:At present, the research on the participation of electric vehicles in the power system frequency modulation mainly focuses on the participation of the electric vehicle as a distributed power source in the system frequency modulation, while the research on the electric vehicle as a controllable load participates in the frequency modulation of the system is less. However, as a distributed power and controllable load, the electric vehicle is of equal importance to its participation in the system FM. Based on this, the model of charging and discharging static frequency characteristic of electric vehicle is taken into account. In the case of power system load disturbance, the coordinated control of charge and discharge of electric vehicle is realized, which makes it convert between the two roles of distributed power and controllable load. On this basis, a single area system for charging and discharging of electric vehicles is established. The model of load frequency control is extended to two area interconnected system. The model is modeled and simulated in MATLAB/Simulink. The example shows that the electric vehicle as a distributed power and controllable load participates in the system frequency modulation, which can not only make the system frequency adjustment faster, reduce the frequency deviation of the system effectively, but also reduce the frequency of the system. The spare capacity of the traditional FM unit.
