| 中文摘要: |
| 负荷频率控制（load frequency control，LFC）问题一直是电力系统设计和运行的主要问题之一，随着多区域互联电力系统规模的不断扩大、结构的不断变化和复杂性的不断提高，频率控制问题变得越来越重要。在实践中，大多数文献通常采用优化算法或者高阶控制器，但是在现实中设计与实现比较困难，频率控制系统最常用的还是简单的比例积分(proportional integration，PI)控制器。然而，由于PI控制器参数通常基于经典或试错方法进行调谐，因此无法在多区域电力系统的大范围运行条件和各种负载变化情况下获得良好的动态性能。针对这一问题，本文将LFC系统综合表述为H∞鲁棒控制问题，并采用迭代线性矩阵不等式算法求解多区域电力系统的鲁棒PI控制器。最后,基于Matlab/Simulink平台对互联三区域频率控制系统进行仿真验证，结果表明，所得到的控制器可以最小化干扰的影响并保持优良的鲁棒性能。 |

| The problem of load frequency control (LFC) has always been one of the main problems in the design and operation of power systems. With the continuous expansion of the scale, the constant change of the structure and the continuous improvement of the complexity of multi-regional interconnected power systems, the problem of frequency control has become more and more important. In practice, most of the literature usually uses optimization algorithms or higher-order controllers, but in reality it is difficult to design and implement, and simple proportional integration (PI) controllers are most commonly used in frequency control systems. However, because PI controller parameters are often tuned based on classical or trial-and-error methods, good dynamic performance cannot be obtained under a wide range of operating conditions and various load variations in multi-region power systems. To solve this problem, the LFC control system is synthesized as a robust control problem, and the iterative linear matrix inequality algorithm is used to solve the robust PI controller of multi-region power system. Finally, the interconnected three-region frequency control system is simulated based on Matlab/Simulink platform, and the results show that the controller can minimize the influence of interference and maintain excellent robustness. |
