The invention provides a method for correcting and determining the minimum active power of a new energy station participating in direct electricity purchase of large users. The correcting and determining method comprises the steps that A cross-section data related to participating in direct electricity purchase of large users are acquired; B the required generating capacity on the day of the new energy station is calculated according to the direct electricity purchase contract power of large user and the new energy station, and the active power of the new energy station at each time of the dayis calculated according to the required generating capacity on the day, and equally divided according to time; C the power prediction value of the new energy station at each time of the day is acquired, and the active power of the new energy station at each time is adjusted according to the power prediction value to acquire the final minimum active power of the new energy station; and D steps B and C are repeated until t
