研究目的
To analyze a hybrid photovoltaic/fuel cell power generation system with a novel induction motor-based compressor for hydrogen pressure enhancement and a fuzzy logic-based MPPT system, aiming to improve system performance and efficiency through coordinated control.
研究成果
The paper concludes that the proposed hybrid PV/FC system with a fuzzy logic-based MPPT and induction motor-driven compressor effectively enhances hydrogen pressure and improves system performance. Simulations show satisfactory operation under varying conditions, with the compressor reducing hydrogen storage time and the coordinated control scheme optimizing power utilization. The model provides a foundation for further research, but real-world testing is recommended for validation.
研究不足
The study is based on simulation models in MATLAB/Simulink, which may not fully capture real-world complexities and uncertainties. Physical validation with experimental setups is lacking. The system's performance is evaluated under specific assumed conditions, and scalability or practical implementation challenges are not addressed. Optimization of parameters and handling of extreme operating conditions could be areas for improvement.
1：Experimental Design and Method Selection:
The study involves mathematical modeling and simulation of a hybrid PV/FC system with components including a solar PV system, fuzzy logic-based MPPT, phosphoric acid fuel cell (PAFC), electrolyzer, hydrogen storage tank, induction motor-driven compressor, and power electronics interfaces. The model is developed and simulated in MATLAB/Simulink to analyze system performance under various conditions.
2：Sample Selection and Data Sources:
Simulations are conducted using predefined operating parameters for system components, such as irradiation levels, temperatures, and pressures, as detailed in the appendix of the paper. No physical samples or external datasets are used; all data is generated through simulation.
3：List of Experimental Equipment and Materials:
The equipment includes MATLAB/Simulink software for simulation, with models for PV arrays, FC systems, electrolyzers, compressors, induction motors, DC-DC boost converters, and PWM inverters. Specific brands or models are not mentioned; the focus is on theoretical models and parameters.
4：Experimental Procedures and Operational Workflow:
The simulation involves setting up the hybrid system in Simulink, applying varying conditions (e.g., changes in irradiation, temperature, hydrogen pressure), and running simulations to observe outputs such as voltage, current, power, and pressure dynamics. The coordinated control scheme is implemented to manage power flow between sources based on load demand.
5：Data Analysis Methods:
Results are analyzed through graphical plots and numerical values from simulations, assessing performance metrics like power output, efficiency, and response times under different scenarios. Statistical methods are not explicitly mentioned; analysis is qualitative and based on simulation outputs.
