New energy grid-connected control method and device, computer equipment and storage medium

The invention relates to a new energy grid-connected control method and device, computer equipment and a computer readable storage medium. The method comprises the following steps: acquiring power grid frequency in real time; under the condition that the difference value between the power grid frequency and the power grid rated frequency is smaller than a first threshold value, the frequency modulation coefficient of the new energy participating in the primary frequency modulation of the power grid is kept unchanged as a preset fixed value; and when the difference value between the power grid frequency and the power grid rated frequency is greater than a second threshold value, dynamically adjusting the frequency modulation coefficient of the new energy participating in the primary frequency modulation of the power grid based on the power grid frequency. According to the method, the rapidity of power adjustment of new energy is fully excavated, and different frequency modulation coefficient setting schemes ar
