Abstract

The invention discloses a control method, system and equipment for a combined heat and power supply unit of a hydrogen fuel cell. The control method comprises the steps: acquiring the peak regulation requirement of a power grid and / or a heat supply network, and generating a peak regulation signal; inputting the peak regulation signal into a predictive control model of a hydrogen compressor, determining an output signal of the air compressor, and sending the output signal to the air compressor, so that the air compressor adjusts the hydrogen pressure output to a hydrogen fuel cell according to the output signal; determining the number N of hydrogen fuel cell monomers needing to work according to the peak regulation requirement; and sending the number of the hydrogen fuel cell monomers to the hydrogen fuel cell, so that the hydrogen fuel cell carries out PID control on the N hydrogen fuel cell monomers, and control parameters of the PID control are predetermined. According to the invention, the complexity of the model can be reduced while the control performance of the system is considered, and the average comprehensive energy efficiency of the hydrogen fuel cell cogeneration system can be effectively improved through sub-unit PID control, so that the economical efficiency, the reliability and the flexibility of the system are guaranteed on the whole.

Description

technical field [0001] The invention relates to the technical field of hydrogen fuel cell modeling and control, in particular to a control method, system and equipment for a hydrogen fuel cell cogeneration unit. Background technique [0002] As the load peak-to-valley difference continues to increase, the power generation efficiency and stability of the integrated energy system are affected more and more significantly. The traditional peak-shaving unit on the generating side can no longer meet the safe, economical and clean peak-shaving advocated today. demand. How to effectively use the interaction between distributed energy, energy storage devices and various loads in the integrated energy system to solve the peak shaving demand, enhance the consumption rate of renewable energy, and improve the economy and safety of the integrated energy system operation is the future. A major challenge for the operation and control of integrated energy systems. [0003] Hydrogen energy ...
