Solar Power Optimization using BFO Algorithm

Searching energy sources to satisfy the world's growing demand is one of the foremost challenges for the next coming century. The challenge is to convert the sunlight to electricity via solar cells is dramatically reducing $/watt of delivered solar electricity. The diurnal and seasonal movements of earth affects in the radiation intensity on solar systems. In this paper, tracking the movement of the sun to get the maximum power direction to compensate the solar system motions, keeping the best orientation relative to the sun has been investigated. A dynamic rapid method for tracking the maximum power angle of solar cell arrays known as Bacteria Foraging Optimization (BFO) algorithm has been used. Experimental analysis is presented for the comparison of different positions of the sun for maximum power alignment.
