The invention discloses a wind power consumption capability model optimization control method and system. The method includes the following steps: based on wind power incoming moment and time length,calculating the wind power amount; based on the pre-established basic unit model of a resistance furnace, the wind power amount and the time length, calculating the consumable electricity of the resistance furnace and the residual electricity and the residual time; and based on the residual electricity and the residual time, calculating the number of the auxiliary equipment that are put into operation. According to the invention, the technical solution can influence the power and operation time of equipment by regulating the operation loads of the equipment and the transformer, and can changepower consumption so as to consume electricity. The method herein is easy, fast and can reduce the amount of wind curtailment.
