摘要:
针对区域互联电网自动发电控制(AGC)过程中系统间传输时延的随机性与差异性问题,提出一种分布式模型预测控制(DMPC)方法.首先,在考虑互联电网区域时延存在差异性的前提下,构建互联电网AGC系统模型;然后,针对互联电网AGC系统的分布式特征,对DMPC方法进行讨论,分析在DMPC框架下时延的处理模式;最后,分别以阶跃与随机负荷曲线为扰动变量,获取互联电网频率控制效果曲线.仿真结果表明:在考虑区域间时延随机性与差异性的情况下,所提方法能够保证系统良好的动态响应性能,验证了此方法的可行性和有效性.
Abstract:
For the randomness and difference of time delay between regional interconnected power grid in automatic generation control(AGC)research field, a distributed model predictive control(DMPC)strategy is proposed in this paper. Firstly, the AGC system model of two regional interconnected power grid is built with consideration of the difference of time delay. Then, aiming at the distribution characteristics of interconnected power AGC system, the DMPC method is discussed, and the processing mode of time delay under DMPC framework is also analyzed. Finally, the frequency control effect curves of the interconnected power grid are obtained by using the step and random load curves as input variables. The simulation results show that the system has a good dynamic response performance under the consideration of the randomness and difference of the time delay, and the feasibility and effectiveness of the proposed method is also verified.
