Method for designing automatic generation control model under grid connection of intermittent energy

The present invention relates to the field of grid-connected operation of renewable energy power generation, and particularly relates to a method for designing an automatic power generation control model in an intermittent energy grid connection, comprising the steps of: A. constructing a time-amplitude two-dimensional disturbance source of a grid-connected intermittent energy disturbance; B. analysing the power grid power fluctuation characteristics; C. determining a distribution scheme of automatic generation control (AGC) system sets; D. determining the standby size of a power supply of an AGC system and the type of power supply; E. making a control policy for the AGC system; F. selecting a frequency bias factor; and G. determining a parameter design scheme of the AGC model. The present invention relates to the influences of large-scale wind power and solar photovoltaic power supply on secondary frequency modulation of a power grid, and can construct an AGC model and parameters on the basis of same, thereby effectively coping with the power disturbance of the intermittent wind power and photovoltaic power supply, improving the secondary frequency modulation effect of the power grid under the fluctuation of the intermittent energy power supplies and improving the ability of the power grid to accept renewable energy resources.
