Identification and control method of power grid impact load disturbance

The invention relates to an identification and control method of power grid impact load disturbance. The method includes the steps of collecting and processing data, judging whether impact load is generated, calculating deviation of the impact load, judging whether the impact load is generated, controlling calculation of the deviation in an area, controlling filtering of the deviation in the area, adjusting power calculation in the area, adjusting power distribution in the area, and monitoring and controlling performance tests in a standby mode. According to the method, control for the impact load is achieved by judging generation of the impact load through continuous sampling for data of a data collection and monitoring control system, and correcting the basic rate and integral adjustment power of load frequency control, and the method guarantees safe operation of a power grid, restrains influences of the impact load on the power grid, and has a significant meaning for wide population.
