The invention belongs to the technical field of
wind power plants, and discloses a
wind power plant AGC and primary
frequency modulation system coordination control method and device, and the method comprises the steps: S1,
system initialization and parameter configuration; s2, real-
time data monitoring and preprocessing; s3, dynamic priority allocation execution; s4, power prediction and instruction correction; and S5, switching and recovering the control right. Through multi-dimensional innovation, the stability and economical efficiency of grid-connected operation of the
wind power plant are remarkably improved; according to the technology, AGC and primary
frequency modulation functions are integrated, parallel control is achieved through a hardware isolation channel, the
frequency modulation response speed is smaller than or equal to 20 ms, and the AGC instruction correction period is smaller than or equal to 50 ms. The
pitch angle subsection control and the
virtual inertia control are cooperated, so that the frequency drop is effectively inhibited; a
fuzzy logic controller is adopted to dynamically allocate response weights, the LSTM neural network is combined to predict a power value in the next five seconds, and an AGC instruction is optimized through a
PID controller to adjust the step length; the
particle swarm algorithm optimizes a frequency modulation dead zone threshold value, the
genetic algorithm sets PID parameters, and the frequency
recovery time is shortened.
