Abstract

The measured wind data of Local Government Engineering Department (LGED) for 2006 at 30Â m height shows a good prospect for wind energy extraction at the site. For a few months and hours the speed is below the cut in speeds of the available turbines in the market. The predicted solar radiation data from directly related measured cloud cover and sunshine duration data of Bangladesh Meteorological Department (BMD) for 1992-2003 indicates that a reliable power system can be developed over the year if the solar energy technology is merged with the wind energy technologies for this site. This research work has studied on optimization of a wind-photovoltaic-battery hybrid system and its performance for a typical community load. The assessment shows that least cost of energy (COE) is about USD 0.363/kWh for a community using 169Â kWh/day with 61Â kW peak and having minimum amount of access or unused energy. Moreover, compared to the existing fossil fuel-based electricity supply, such an environment friendly system can mitigate about 25Â t CO2/yr. The analysis also indicates that wind-PV-battery is economically viable as a replacement for conventional grid energy supply for a community at a minimum distance of about 17Â km from grid.
