| 中文摘要 |
| 本文研究了一类计及电动汽车的电力系统中的负荷频率控制问题, 首先, 将电动汽车模型与传统的负载频率控制模型相结合,在未知扰动波动范围的条件下设计了自适应滑模控制律. 其次, 分别考虑了电网调频中的匹配扰动和不匹配扰动问题, 并利用李亚普诺夫稳定性理论导出了匹配和不匹配条件下的系统稳定的充分条件. 最后, 两个区域电力系统的仿真结果表明, 电动汽车作为电源和负载都可以提高电网的频率稳定性, 所设计的控制器可以有效地调节电网的频率波动. |
| 英文摘要 |
| This paper studies the load frequency control (LFC) of power system with electric vehicle (EV). Firstly, combining the EV model with the traditional load frequency control model, an adaptive sliding mode control law is designed under unknown disturbance fluctuation range. Secondly, the matched and unmatched disturbances in power network frequency modulation are considered, and the sufficient conditions for system stability under matched and unmatched conditions are derived using Lyapunov stability theory. Finally, the example of two regional power systems shows that the electric vehicle as both a power source and a load can improve the frequency stability, and the control schemes can adjust the frequency fluctuation of the power grid. |
