OPTIMIZATION TECHNIQUES FOR THE ECONOMIC DISPATCH PROBLEM IN VARIOUS GENERATION PLANT

The dynamic economic dispatch (DED) occupies important place in a power system’s
operation and control. It aims to determine the optimal power outputs of on-line generating units in
order to meet the load demand and reducing the fuel cost. The nonlinear and non convex
characteristics are more common in the DED problem. Therefore, obtaining a optimal solution
presents a challenge. In the proposed system, firefly algorithm, Adaptive simulated annealing
algorithm, artificial bee colony (ABC) algorithm – a recently introduced population-based
technique – is utilized to solve the DED problem. A general formulation of this algorithm is
presented together with an analytical mathematical modeling to solve this problem by a single
equivalent objective function. The results are compared with those obtained by alternative
techniques proposed by the literature in order to show that it is capable of yielding good optimal
solutions with proper selection of control parameters.
