摘要:
为了有效改善多区域互联电网的动态稳定性,提出一种分散式模糊PID负荷频率控制方法.该方法为互联电网每个区域设计一个模糊PID控制器,以区域频率偏差和联络线功率偏差为控制目标,根据区域控制偏差的变化量,运用模糊推理,在线修正PID调节参数,从而控制互联电网快速趋于动态稳定.针对三区域环型互联电网,考虑发电速率的限制,对其负荷扰动和模型参数摄动进行仿真.结果表明:与传统PID算法相比较,所提出的方法具有更强的适应性、鲁棒性及扰动抑制能力,能使系统取得更好的动态控制性能.
Abstract:
In order to effectively improve the dynamic stability of multi-area interconnected power grids, a load frequency control method based on decentralized fuzzy-PID algorithm is proposed in this paper. In this method, a fuzzy-PID controller is designed in each area of interconnected power grids. The control system takes the errors of the area frequency and tie-line power as control objectives. According to the variation of area control error, the PID regulating parameters are revised online by using fuzzy reasoning. And this method can make the interconnected power grid achieve dynamic stability quickly. Aiming at the three-area ring interconnected power grid, when considering generation rate limiting, load disturbance and model parameter perturbation are simulated. Simulation results show that the proposed method has stronger adaptability, robustness and disturbance rejection ability. And can make the system obtain better dynamic control performance in contrast with the traditional PID method.
