APPLICATION OF ABC ALGORITHM FOR ACTION BASED DISPATCH IN THE RESTRUCTURED POWER SYSTEMS

This paper addresses an Artificial Bee Colony (ABC) based method to search and find global solution on auction based dispatch algorithm in a deregulated power system. For this reason, the generation cost is replaced by seller’s bidden cost function including not only the generation cost, but also the market strategy, which may become concave, whereas the conventional Economic Load Dispatch (ELD) algorithm relies on the convexity of the cost function. The scheduling problem of an auction-based dispatch problem in a deregulated power system is formulated as the least bidden cost optimization problem, in which the seller’s total bidden cost is minimized while the balance of supply and demand constraint and the capacity limit constraints are satisfied. It is solved by ABC algorithm which describes the food foraging behavior, memorizing and information sharing characteristics of honey bee swarm to find the best possible solution within a reasonable computation time. The plausibility of the proposed algorithm is demonstrated and its performance is compared with other methods on 3 and 8 machines standard power systems. Simulation results reveal that the proposed ABC based solution method has better outperforms than the other algorithms.
