说明：  利用 ＭＰＣ算法使得由发电机参数摄动和负荷扰动形成的电网频率波动减小。为验证所提出方案的有效性，建立三区域互联电力系统频率响应模型并仿真，将 MPC算法与常规的PID算法控制效果进行比较。结果表明，在负荷扰动、参数摄动和有通信延迟的情况下，MPC技术对互联电网的负荷频率控制性能均优于PID控制
(The MPC algorithm is used to reduce grid frequency fluctuations caused by generator parameter perturbations and load disturbances. In order to verify the effectiveness of the proposed scheme, a three-zone interconnected power system frequency response model is established and simulated, and the MPC algorithm is compared with the conventional PID algorithm. The results show that under load disturbance, parameter perturbation and communication delay, MPC technology is better than PID control for the load frequency control performance of the interconnected power grid.)
