Research on Key Technology of Hydrogen-Electricity Coupling and Engineering Demonstration
The commissioning of the first phase of the Hydrogen and Electricity Deep Coupling Innovation Demonstration Project in the Hydrogen Zero Carbon Power Industrial Park has effectively improved the coupling of the hydrogen and electricity systems, improved the poor electrical and thermal response of the system due to the mismatch between renewable energy power generation and the load demand, and given full play to the key role of the hydrogen and electricity coupling system in the scenarios of frequency regulation, peak shifting, emergency response, and other scenarios.Relying on the specific practice of the construction of the first phase of the project, the background of the construction of the demonstration project and its core sub-systems are first introduced.Then the hybrid electrolyser used in the first phase of the construction of the hybrid electrolyser for synergistic hydrogen production and the capacity configuration scheme, and the optimal performance of the device-level control strategy of the proton exchange membrane fuel cell system are introduced.Finally, it summarises the construction of the first phase of the project and discusses in depth the difficulties that should be tackled in the subsequent construction of the demonstration project from the aspects of strengthening the research and development of the relevant core equipments in the system, strengthening the research on the integrated control strategy of combined heat and power supply under the hydrogen-electricity coupling system, and strengthening the research on the auxiliary service of the hydrogen-electricity coupling system to participate in the electric power system.
