Case study: Tidal current energy potential in Bangladesh

In developing country like Bangladesh, the demand of electrical energy is very higher than the available production. At present, the electricity supply deficiency is about 1500 to 2000 MW /day i.e. the total supply is 4000 to 4500 MW/day within the demand of 6000 MW/day for this reason power failure has become an acute problem in our country. To solve this energy crisis, it is Important to found alternative approaches. Recently Tidal power becomes most important and researchable topic in the world, especially the countries which are placed near sea or ocean. Bangladesh is situated between 20°34' and 26°38' north latitude, 88°01' & 92°41' east longitude with an area of 147570 sq.km. It has a 710 km of coastal line along the Bay of Bengal [13]. As Bangladesh has a long coastal line along the Bay of Bengal, so tidal energy technology can be used as one of the major reliable energy resource. In this paper an efficient tidal energy site is proposed based on analysis of technical as well as market data and the data is collected from Bangladesh Navy and different tidal current data chart. Finally based on tidal current condition of one of the efficient site, a MATLAB simulink simulation result is shown by proposed a suitable electrical generator.
