自动发电控制(automatic generation control,AGC)是现代化电网运行控制的重要技术之一,承担着电网频率调节、网间联络线交换功率控制和经济调度的重要任务。现代电网已逐步发展为复杂的大系统,对AGC系统提出了更高的要求,传统的控制方法在应用中存在一些问题。智能控制技术更符合人的思维习惯,易于理解和掌握,为自动发电控制提供了新的思路。将模糊控制和预测控制技术用于AGC,提出了一种智能AGC控制器,采用实际电网数据进行仿真验证,结果表明,该算法具有更好的适应性。
Automatic generation control (AGC) is one of the most important technologies for modern grid operation and control. It undertakes the important tasks of grid frequency regulation, switching power control of interconnection lines and economic dispatching. Modern power grid has gradually developed into a complex large-scale system, which sets higher requirements for AGC systems. There are some problems in the application of traditional control methods. Intelligent control technology more in line with people’s thinking habits, easy to understand and grasp, provides a new idea for automatic power generation control. By using fuzzy control and predictive control technology for AGC, an intelligent AGC controller is proposed, which is verified by real grid data. The results show that the proposed algorithm has better adaptability.
