Abstract

Multi-objective environmental/economic dispatch (EED) problem is the scheduling of generators which fulfill the load demand of the power plants using fossil fuel and also making combined production, in order for them to perform with minimum cost and emission. Actually, this is an optimization problem. In this study, multi-objective EED solution has been recommended by using artificial bee colony (ABC) algorithm. For the solution of the problem, multi-objective EED was converted into single-objective EED by using price penalty factor. In this study, the obtained results from ABC algorithm were compared to those of other algorithms in the literature. The results obviously show that ABC algorithm produce better results.

Key words: Economic dispatch, emission dispatch, artificial bee colony, multi-objective function, price penalty factor.
