The invention discloses a wind turbine generator optimization commissioning and quitting method considering participation of wind and light in primary frequency modulation, and relates to the technical field of power systems, and the method comprises the following steps: building a model, sorting units, obtaining a mathematical relationship of power grid frequency, combining an optimization model, converting a linear programming model, and obtaining an optimization result. By optimizing distribution of active power needing to be added to a wind turbine generator in a wind power plant and a time sequence control strategy for quitting frequency modulation and optimizing the effect that a thermal power generating unit participates in frequency modulation under the assistance of wind power, secondary impact when the wind turbine generator quits frequency modulation is reduced, efficiency and stability of the process are improved, and energy consumption is reduced. And through a primary frequency modulation contro
