Abstract:

Aiming at the problems of multiarea economic dispatch( MAED ) of the power system, such as tie line transmission losses ,multiple fuels, valvepoint loading and prohibited operating zones, we design a mathematical model in which  the requirement of the minimum cost of multiarea power load is taken into account and the artificial bee colony optimization is utilized to quickly search for the global optimal solution. The effectiveness and feasibility of the proposed algorithm have been verified on two different test systems, both small and large, involving varying degrees of complexity. Compared with algorithms including differential evolution, evolutionary programming and real coded genetic algorithm, the proposed algorithm is a promising alternative approach for solving the MAED problems in practical power system.
