AI Technical Summary
Existing technologies fail to effectively consider the impact of photovoltaic power fluctuations on the durability of materials inside proton exchange membrane electrolyzers, leading to electrolyzer performance degradation and shortened equipment lifespan. Furthermore, the optimization algorithms are highly complex and lack systematic solutions.
A coupled dynamic analysis model of photovoltaic and electrolyzer is constructed to identify key electrical operating state variables, determine durability operation constraints, and determine the configuration ratio of photovoltaic capacity to electrolyzer capacity by solving a nonlinear differential equation system. A method and system for configuring the photovoltaic-hydrogen capacity ratio are established to reduce optimization complexity.
It significantly extends the service life of the electrolyzer, reduces algorithm complexity, improves the economy and reliability of the system, and achieves durability matching of the equipment under rapid photovoltaic fluctuations.
