The invention provides an optimal configuration method and system for adjusting power supply capacity, and belongs to the field of power grid optimization, and the method comprises the steps: collecting a load value, a new energy prediction output value and a new energy actual output value of each time period in a typical day, and determining the day-ahead power abandoning rate of a power system; based on capacity boundary judgment conditions, a power abandoning rate-adjusting power supply capacity relation curve is established, when the change of the curve tends to be stable, a corresponding stable point is an adjusting power supply absorption promoting capability saturation point, and the power abandoning rate at the adjusting power supply absorption promoting capability saturation point is an ideal power abandoning rate; determining an electricity abandoning rate constraint according to the day-ahead electricity abandoning rate and the ideal electricity abandoning rate; and based on the power abandoning ra
