为了提升电力系统运行稳定性，研究电力系统自动发电控制(AGC)与一次调频协调的固定时间量化反馈控制方法，达到快速调节电力系统的有功功率，提升量化反馈控制的效果。以各机组位于振动区和限制运行区的最小加权时间为目标函数，以固定响应延迟时间、机组功率爬升固定时间一致性与机组开停机固定时间约束等为约束条件，并引入迟滞量化器，建立AGC与一次调频协调固定时间量化反馈控制优先级模型，用于确定各机组的优先级顺序；按照优先级顺序，结合AGC与一次调频协调策略，为各机组分配有功功率，完成电力系统AGC与一次调频的固定时间量化反馈控制。实验证明：在不同扰动情况下，所提方法均可有效完成量化反馈控制，令电力系统的有功功率快速达到目标值，且各机组功率爬升固定时间一致性约束的收敛速度较快。

In order to improve the operation stability of power system, a fixed time quantitative feedback control method for coordinated automatic generation control(AGC) and primary frequency regulation in power system is studied, so as to quickly adjust the active power of power system and improve the effect of quantitative feedback control. Taking the minimum weighted time of each unit in the vibration zone and the restricted operation zone as the objective function, taking the fixed response delay time, the consistency of unit power climbing and the fixed time constraint of unit startup and shutdown as the constraint conditions, and introducing the hysteresis quantizer, the priority model of AGC and primary frequency modulation coordination fixed time quantized feedback control is established to determine the priority of each unit. According to the priority order, combined with the coordination strategy of AGC and primary frequency modulation, the active power is allocated to each unit to complete the fixed time quantitative feedback control of AGC and primary frequency modulation in power system. Experimental results show that the proposed method can effectively complete quantitative feedback control under different disturbance conditions, so that the active power of the power system can reach the target value quickly, and the convergence speed of the power climbing of each unit is fast.
