In order to enhance the efficiency of renewable energy utilization and the economic and environmental performance of distributed electric-thermal-hydrogen energy systems,a unified model for multi-type electrolyzers is established considering the strong fluctuation of wind and solar power generation and the differentiated features of multi-type electrolyzers.A method for optimizing the design of electric-thermal-hydrogen energy systems is pro-posed,taking into account the differentiated characteristics of multi-type electrolyzers.This method comprehen-sively utilizes alkaline electrolyzers,proton exchange membrane electrolyzers,and solid oxide electrolyzers,consid-ering their differences in terms of economic viability,flexibility,and efficiency.This approach aims for consump-tion of renewable energy sources with different fluctuation characteristics.Case study results indicate that this method effectively integrates the differentiated features of multi-type electrolyzers,aligning the operational flexibil-ity of various electrolyzers with the fluctuations in wind and solar power outputs.As a result,it comprehensively en-hances the economic and environmental performance of electric-thermal-hydrogen energy systems.
