The invention provides a wind power quality quantification segment method based on optimization calculation. The method comprises steps that (1), an optimization target model of a wind power segment is established; (2), a set combination optimization scheduling model taking consideration of wind power is established; (3), the wind power segment is acquired through optimization calculation; and (4), smooth load equivalent scheduling is carried out, and the wind power segment method is verified. According to the method, the wind power quality segment optimization model is established, based on the optimization calculation method, quantification segment for the wind power is carried out, and decision bases are acquired for wind power segment scheduling and optimal wind power reception.
