Abstract
New energy connected to power grid brings new challenges to optimal operation of power systems. The transient stability of power grid mainly depends on primary frequency compensation of thermal power units. By analyzing the theory and practice of DEH and coordinated control system(CCS) of thermal power units, combined with the insufficient of actual primary frequency compensation strategy response to frequency of accidents, the optimization of primary frequency compensation of subcritical thermal power unit’s frequency control and fuel-air control were offered. The practical application results show that the proposed control strategy can effectively control the subcritical thermal power units to achieve the stability of power grid primary frequency.
