Enhanced Artificial Bee Colony Optimization for Fixed Head Hydrothermal Power System

Enhanced Artificial Bee Colony Optimization (EABCO) algorithm is presented in the paper for economic power dispatch of both thermal plants and hydro power units (fixed head) together. Different constraints considered in this paper are transmission losses, ramp rate limits of thermal generators. Two different cases are taken and the numerical results obtained are studied to test the effectiveness of this suggested technique. The results of the recommended technique are analized with the results already acquired from existing algorithms like differential evolution and evolutionary programming. This comparison draws the conclusion that the EABCO can provide better results and solution than the existing methods in terms of minimum time of computation and low fuel cost.
