The invention discloses a new energy automatic power generation control method and system considering output uncertainty. The method comprises the steps of each round of automatic power generation control: calculating the output uncertainty gamma i of each new energy power station i according to historical power data and power prediction data; calculating AGC instruction values delta PACEi allocated to the new energy power stations i according to the output uncertainty gamma i and the ACE power total value delta PACE needing to be adjusted by the new energy power stations in the current roundof region; and issuing the AGC instruction value delta PACEi of each new energy power station i to each new energy power station i for execution. The output uncertainty of the new energy power stationis measured by using historical prediction accuracy, the ACE power is distributed according to the output uncertainty of the new energy power station, and the influence of the uncertainty of new energy power generation on the
