Generally, hourly measured source and load data are used to size stand-alone hybrid energy system. However, the power generated by wind turbines and PV panels change rapidly because of the continuous fluctuation of wind speed and solar radiation. Therefore, these fluctuations must be considered in sizing stand-alone hybrid energy system. On the other and,(More)
BACKGROUND In this study, starch and polycaprolactone (PCL), composite nanofibers were fabricated by co-axial needle electrospinning technique. Processing parameters such as polymer concentration, flow rate and voltage had a marked influence on the composite fiber diameter. Fourier transform infrared spectroscopy, scanning electron microscopy (SEM),(More)
Wind speed profile in the atmospheric layer is critical factor for wind turbine capacity factor estimation. Prior to the installation of wind farm, it is essential to estimate expected energy output in order to assess the economic viability of the project. Wind speeds measurements are generally carried out at 10 or 30 m whereas most turbines in commercial(More)
