研究目的
To estimate the yield of photovoltaic power plant grid-connected based on photovoltaic model and loss model in MATLAB/Simulink.
研究成果
The method effectively estimates the final yield of photovoltaic grid-connected systems with a system loss of 28%. The gap between simulation results and PVGIS software ranges from -1.47 to 4.64 MWh/Month. The system offers flexibility in adjusting loss parameters based on weather conditions and reduces simulation software costs.
研究不足
The study is limited to three locations in Vietnam and uses a specific PV module model. The accuracy depends on the solar radiation data and loss parameters.
1：Experimental Design and Method Selection:
The study uses MATLAB/Simulink to develop a photovoltaic-yield model based on a one diode model for commercial PV modules and a loss model including various system losses.
2：Sample Selection and Data Sources:
Solar radiation data from three locations in Vietnam (Ba Ria Vung Tau, Ho Chi Minh, Binh Duong) are used, extracted from PVGIS software.
3：List of Experimental Equipment and Materials:
A commercially available PV module (JAM60S03320/PR) with a rated power of 320 Wp is used.
4：Experimental Procedures and Operational Workflow:
The photovoltaic-yield model is developed and simulated in MATLAB/Simulink, comparing results with PVGIS software.
5：Data Analysis Methods:
The yield and losses are analyzed, and the gap between simulation results and PVGIS software is evaluated.
