光伏PEM电解水制氢系统仿真与控制OA

Hydrogen energy,with its advantages of diverse sources and clean,low-carbon characteristics,represents a highly promising energy form for the future.Among various electrolytic hydrogen production routes,Proton Exchange Membrane(PEM)electrolysis is more suitable for renewable energy integration due to its wide load range and fast response.With the continuous decline in photovoltaic(PV)power generation costs,developing PV-powered hydrogen production technology will convert the surplus electricity from renewable energy into hydrogen energy,without carbon emissions throughout the whole process.This has significant strategic importance under China's"Dual Carbon"policy framework.Addressing current limitations in PV-hydrogen simulation like focusing solely on electrical characteristics and poor dynamics,this paper establishes an electrochemical-thermodynamic dynamic coupling model for PEM electrolysis systems on the Matlab/Simulink platform.By matching PV module parameters with PEM electrolyzer system requirements,PV array configurations and BUCK converter parameters are designed to enable the system to produce hydrogen at rated capacity under peak irradiance,achieving holistic simulation and control of the PV electrolytic hydrogen system.Simulation results validate the correctness of the matching design and the effectiveness of the control strategy,providing a reference for PV-powered hydrogen technology research.
