Statistical analysis of wind power potential at Pakshey River delta region

Wind energy is now being used in almost every country of the world as an important and pollution free renewable source of energy. In Bangladesh, research in the field of wind energy began only a few years ago. Wind power potentials of the Pakshey River delta region have been statistically analyzed based on the 10 min duration wind speed data in the river delta region. The hourly and monthly wind speed and wind power density are assessed to have remarkable variations and Weibull distribution function has been derived from the available data with its two parameters identified. First of all the wind data of the river delta region in Bangladesh from January to December, 2006 is to be collected and sorted in sequence in appropriate frequency. The data are further analyzed and converted into several useful parameters, like daily mean wind speed, monthly mean wind speed, and mean annual wind speed. After that, the velocity frequency bar graph, energy bar graph, velocity duration curve, etc. have been plotted and analyzed. Weibull shape factor (K) and scale factor (C) has been calculated and plotted by implying different methods. The wind power potential of this side was found to be encouraging; however, the wind power at different site varies significantly. So, wind energy potential in river delta region and coastal region has well prospect for choosing wind power plant in Bangladesh
