Due to the increasing scale of new energy and the increasingly close interconnection of regional power grids, higher requirements are put forward for the adjustment of active power under power grid faults. Automatic generation control(AGC) is an important function of the energy management system(EMS), it controls the output of the frequency modulation units, and keeps the system in a safe and stable operating state. By analyzing the basic principle and assessment index of AGC control, combined with AGC control process, the emergency active power control strategy of thermal power unit is proposed. By cooperating with AGC of superior dispatching, the effective suppression of power grid fluctuation is realized, which provides effective protection for grid security control.
