| 摘 要： | 大量电动汽车无序接入电网会给电力系统安全稳定运行带来危害。利用汽车入网技术，电动汽车接入电网参与系统调频，但用户出行需求、电池损耗会受到影响。基于此，首先分析了电动汽车动力电池特性，建立了电动汽车参与系统调频模型，通过分析电动汽车动力电池荷电状态概率密度分布，提出考虑电池荷电状态的电动汽车参与系统调频控制策略。最后，模拟了以平抑电网频率波动为目标的电动汽车充放电场景，根据电池荷电状态，基于所提控制策略通Matlab/Simulink仿真，验证了电动汽车参与系统调频实际效果。

| Abstract: | A large number of unmanaged electric vehicles (EVs) connected to the power grid brings harm to the safety of the power system. By using the technology of V2G, EVs are connected to grid to participate in the system frequency modulation. However, the demand of batteries will be affected. In this research, by analyzing the distribution of probability density of EV battery state, the strategy of participating in system FM control considering battery state of charge was proposed. Based on the characterristics of battery of EVs, a model was built. The EV charging and discharging scenario, which aims at stability of the frequency fluctuation of the power grid, was simulated. According to the state of SOC of the battery, the simulation results based on the control strategy of Matlab/Simulink verify the actual effect of EV participating in the system frequency modulation. |
