1. An MPC-based hierarchical coordinated control method for a wind-hydrogen coupling system, comprising the following steps:
step (1) dividing the wind-hydrogen coupling system into an upper-layer grid-connected control and a lower-layer electrolytic cell control;
step (2) controlling grid-connected power to track a wind power prediction curve by adopting an MPC control algorithm for the upper-layer grid-connected control, and obtaining an electrolytic cell power control quantity for the lower-layer electrolytic cell control at the same time, wherein the MPC is model predictive control;
step (3) dividing operation states of electrolytic cell monomers into four operation states of rated power operation, fluctuating power operation, overload power operation and shutdown; and
step (4) determining the operation states of various electrolytic cell monomers by adopting a time-power double-line rotation control strategy based on the electrolytic cell power control quantity, thus making the electrolytic cell monomers operate in one of the four operating states in turn.
