研究目的
To develop an integrated thermal and electrical model for Photovoltaic panels using Matlab/Simulink tools, designed for extreme and dusty weather conditions, with the aim of achieving a realistic online simulation that incorporates major environmental variables and uses water mass flow rate for surface cooling to enhance output power.
研究成果
The integrated model effectively reduces PV panel temperature and increases output power through water surface cooling, with up to 26.83% power improvement. It is stable under varying climatic conditions and ready for future controller development, demonstrating its utility in enhancing PV performance in harsh environments.
研究不足
The model is simulation-based and may not fully capture real-world complexities; it is designed for specific extreme conditions and may require validation with physical experiments. Optimization of water usage and scalability to larger systems are potential areas for improvement.
