研究目的
Investigating the efficiency of electrical energy produced in photovoltaic (PV) systems through modeling and parametric simulation studies, and designing a duty ratio controller for a DC–DC converter circuit to maintain a constant output voltage despite input voltage fluctuations.
研究成果
The study successfully modeled a PV system and used ANFIS to predict voltage output with high accuracy. The designed duty ratio controller effectively maintained a constant DC bus voltage despite fluctuations in input voltage, demonstrating the potential for improved efficiency in PV energy systems.
研究不足
The study relies on simulation data and may not fully account for all real-world atmospheric and operational conditions affecting PV systems.
1：Experimental Design and Method Selection
Parametric simulation studies were performed with Ansys-Electronics 2019 R2 software to model a solar panel and analyze the effects of atmospheric and temperature coefficient parameters on PV system efficiency.
2：Sample Selection and Data Sources
482 data points of voltage values produced by the PV panel were obtained from parametric simulations based on cell temperature, ambient temperature, and radiation parameters.
3：List of Experimental Equipment and Materials
Ansys-Electronics 2019 R2 software for simulation studies.
4：Experimental Procedures and Operational Workflow
Data obtained from simulations were used for training in ANFIS algorithms, and the system was tested with estimated values to predict voltage output under varying conditions.
5：Data Analysis Methods
Root mean square error function was used to measure the performance of the ANFIS model in estimating voltage values.
