Flywheel-lithium battery hybrid energy storage wind power plant grid-connected power control strategy

The invention provides a flywheel-lithium battery hybrid energy storage stabilizing wind power plant grid-connected power control strategy, and belongs to the technical field of energy storage control, and the strategy comprises the steps: carrying out the real-time filtering of wind power output through a Kalman filtering algorithm, so as to reduce the hysteresis effect; self-adaptive parameters are introduced, filtering algorithm parameters are adjusted according to the rotating speed of a flywheel energy storage motor and the state of charge of a lithium battery, and stabilization of the power of the wind power plant is achieved; when the wind speed changes suddenly, parameters are adjusted in a self-adaptive mode, and the absorption power of various energy storage devices in the hybrid energy storage system is reasonably distributed; and verifying the effectiveness of the algorithm through a hardware-in-the-loop experiment, and analyzing the stabilizing effect of the hybrid energy storage system.
