Integrated regulation and control method based on refinery water-hydrogen-electricity system

The invention provides an integrated regulation and control method based on a refinery water-hydrogen-electricity system. The refinery water-hydrogen-electricity system comprises a new energy power generation system, a complementary switching device, a first power transformation device, a second power transformation device, a third power transformation device, a fourth power transformation device, a water treatment system, a water electrolysis hydrogen production system, a hydrogen storage system and a refinery hydrogenation technological process system. The integrated regulation and control method comprises the following steps: in double-closed-loop integrated control, a control loop where a water-hydrogen-electricity decision and distribution controller is located forms an outer loop, and a water control loop, a hydrogen control loop and an electricity control loop are used as three parallel inner loops; the hydrogen production amount serves as a final control target, a water treatment system, a water elect
