| 摘 要： | 提出了一种用于多区域互联电力系统的负荷频率综合PI滑模控制方法，该方法同时发挥了基于新区域控制偏差的比例积分控制和滑模控制的优点，选用带积分的滑模超面方程使系统从一开始就进入滑模状态，当系统进入滑模状态后，转化为基于新区域控制偏差的比例积分控制。在考虑发电机变化率约束和具体控有控制死区条件下，所提出的综合控制方法仍能使系统取得较好的性能，而且克服各自单一控制的不足，仿真结果显示该方法是简单的、有效的、并且能够保证整个系统是渐进稳定的。

| Abstract: | A synthetic PI sliding mode control method used for load frequency control of multiarea power systems has been proposed, the method has the advantages of PI and sliding mode control, sliding mode superface with integral item make the system can reach on sliding mode from initial time. After reaching on sliding mode, system is controlled by PI control based on ACEN. When considering generation rate constraint (GRC) and deadband, the proposed synthetic control method can make system to have good performance, and can overcome the disadvantages of each control method. Results of simulation show that the proposed method is simple, effective, and to ensure that the whole systems are asymptotic stable. |
