Area control deviation and unit generation deviation-based scheduling feedback control system

The invention belongs to the field of improvement on power system control technology, and particularly relates to an area control deviation and unit generation deviation-based scheduling feedback control system. By establishing a power grid ACE real-time acquisition system to acquire related frequency, tie-line plan and tie-line real-time data, calculating ACE index values of the power grid per minute and combining ultra-short term load prediction, a novel feedback control system taking load deviation, area control deviation and unit generation deviation into consideration is established so as to guide real-time scheduling of the power grid and establish a corresponding feedback control strategy.
