AGC evaluation and assessment method and device adapted to multi-region interconnected power grid

The invention discloses an AGC evaluation and assessment method and device adapted to a multi-region interconnected power grid. The method comprises the steps that control modes of all control zones are acquired; relevant parameters of the control zones are collected, and ACE values of the control zones are calculated; based on the ACE values of the control zones, different assessment index calculation formulas are adopted for the control zones of different control modes to calculate corresponding assessment index values; based on the calculated assessment index values of the control zones, and different evaluation principles are combined to perform control performance evaluation on the control zones. The AGC evaluation and assessment method and device adapted to the multi-region interconnected power grid is applicable to the situation in which a plurality of control zones exist and the control capability and adjustment characteristics are greatly different between the control zones, on the basis of a CPS con
