ABSTRACT Recently, the extraction of photovoltaic parameters was the subject of intensive debate in the scienti?c literature. This paper presents an analysis and comparison of the use of the statistical errors in extraction of single and double diodes of the solar cell and photovoltaic module parameters. The compared errors are based on the utilisation of the firefly algorithm. The objective function used is adapted to minimise the absolute errors between the experimental and predicted current values. Two technologies of the solar cell are used to compare; a mono-crystalline silicon solar cell and the polycrystalline silicon photovoltaic module with 36 cells connected in series. The performance of the extracted parameters and current is compared with recent algorithms and techniques. The analysis and comparison of commonly used error measure help in evaluating the predictive ability of parameters extraction. The comparisons demonstrate that the firefly algorithm in statistical errors measure provides high performance and accuracy of the extracted parameters. 相似文献

To design a high-performance photovoltaic (PV) system, the parameters extraction of solar cell models is exceedingly crucial. A new variant of the genetic algorithm (GA) called Genetic Algorithm with Convex Combination Crossover (GACCC) is proposed to identify the unknown electrical parameters of different solar cell models, i.e. single diode, double diode, and PV module. GACCC is achieved by integrating a new crossover operation to maintain a good balance between the intensification of the best solutions and the diversification of the search space. To test the proposed GACCC, we have compared it to the basic GA and with other literature techniques. The results indicate a high performance of developed approach GACCC and a high accuracy of estimated parameters. In addition, the efficiency of the results is confirmed by the good agreement between the experimental I-V data and the simulated results in all cases. 相似文献

以强度等级为C30的普通混凝土为研究对象,采用单掺法进行了试验设计,按照0、12.5%、25%、50%、75%、100%等体积代替普通砂,分别制作了50组共150个废玻璃混凝土标准抗压试件和轴心抗压试件,养护3、7、14、28、60d后分别测试它们的标准抗压强度及轴心抗压强度.通过对试验数据和破坏形态的分析,研究了不同的废玻璃代砂率下对混凝土标准抗压强度和轴心抗压的影响.运用回归分析的方法建立了不同废玻璃代砂率下废玻璃混凝土标准抗压强度和轴心抗压强度的预测公式,标准抗压强度与轴心抗压强度的关系式以及标准抗压强度与龄期的关系式. 相似文献

In urban areas with dense buildings,it is expected that the building-integrated photovoltaic( BIPV) system,will become widespread. Especially,the solar photovoltaic blinds( SPB),which can block the sunlight coming into the room and produce electricity,is emerging as a new technology trend. To facilitate the installation of the SPB,this study analyzed the techno-economic performance of the smart SPB considering the PV panel type and solar tracking method used. Towards this end,this study conducted experiments using the developed smart SPB,as well as a comparative analysis in terms of the techno-economic aspects based on the experiment results. The analysis results of this study were as follows: at the same cost,( i) the monocrystalline silicon( mono-Si) PV panel generated 350. 5% more electricity than the amorphous silicon( a-Si) PV panel; and( ii) the direct solar tracking system generated 12. 9% more electricity than the indirect solar tracking method.Accordingly,the mono-Si PV panel and the direct solar tracking method were selected for the optimal smart SPB. The installation of the smart SPB with the proposed optimal design on the south-facing window of buildings can be helpful for raising the electricity selfsufficiency rate of buildings by up to 20. 3%. 相似文献
