The invention relates to a MPPT method of a SMESC wind power system based on IIWO optimization. The method comprises the following steps of: initializing an intrusion weed algorithm parameter; substituting the randomly generated initial solutions Kp and rho s into a constructed Simulink model to calculate fitness values corresponding to each weed, outputting a fan control amount, and feed backingthe optimal speed in the current generation for the maximum power tracking of the fan by the SMESC; sorting the fitness values, and selecting the number of seeds allowed by the maximum number of populations for breeding and regeneration to produce offspring seeds; calculating the number of seeds produced by each weed according to the fitness values; substituting the position information of the offspring weed seeds into the SMESC parameter optimization model, outputting and generating a new control amount and fitness values of the offspring seed; judging whether a termination condition is satisfied; and outputting the
