摘要
由于可再生能源的随机性,大量的风力发电和光伏发电接入电网将会带来频率波动等一系列的问题,智能配网中数目庞大、分散的电动汽车及可中断负荷参与电网的频率控制越来越受到关注。本文在考虑电动汽车电池的充/放电特性的基础上,提出了电动汽车接入电网的频率反馈动态控制模型。在此基础上,进一步提出了包含电动汽车及热水器参与的区域频率动态模型。通过Simulink仿真验证了电动汽车和智能热水器等可中断负荷能很好的平衡可再生能源带来的频率波动。
Due to the randomness of the renewable energy, high penetration of wind and photovoltaic power generation will bring a series of problems such as frequency fluctuations. A large number of Plug-in electric vehicles （PEVs） and controllable loads have been shifting into focus for this. A dynamic vehicle-to-grid （V2G） model with feedback control is proposed by considering the battery charging/discharging characteristics and the dynamic model of frequency regulation with PEVs and controllable loads for a single area is established. Simulation results demonstrate that the application of PEVs and controllable loads can relief the frequency refutation due to the randomness of renewable energy sources.
