  Earlier measurement and study of wind speed for the coastal part of Bangladesh showed that some of the areas of this part would be useful for wind power generation. But till now no measurement at the hub height of wind machine has yet done. Data has been collected from different sources and analysis has been done using logarithmic law and micro scale modeling software, WAsP for wind energy assessment over the coastal part. It has been found that the speed varies from 4m/s to 5.7 m/s at a height of 50m above ground level depending on the land type. Wind power density varies from 100 to 250 w/m2 indicate the wind power can play an important role in the energy sector.

  St Martinís is one of the most beautiful Tourist Islands in Bangladesh where grid connected electric system for the inhabitants will not be possible to establish even in future. Diesel, Kerosene and wood are the main fuels for fulfilling the energy demand. Solar and Wind resources are the hybrid options for the Island. HOMER, a software for optimization of renewable based hybrid systems, has been used to find out the best technically viable renewable based energy efficient system for different numbers of households-1, 20and 50. It shows that per unit (KWh) cost of energy varies from 39.8 to 13.9 taka.

  Hybrid energy system is an excellent solution for power generation in rural areas where the grid is infeasible. Such a system incorporates a combination of one or several energy sources such as solar PV, wind energy units, diesel generators etc. This study discusses various system components for remote area power supplies and then proceeds to an optimal operating strategy of an integrated system for a typical rural village at Kutubdia in Bangladesh. In order to determine the hourly operating states of a hybrid system more accurately, practical mathematical models characterizing PV module, wind generators are used. Battery and diesel generator are used as back up power sources. Quasi Newton algorithm is applied for optimizing the operation of wind and PV integrated energy systems. The result of the case study shows that the cost of electricity is 23 Tk/kWh for a PV/wind hybrid system.
