Abstract :
This paper deals with the application of genetic algorithms and simulated annealing in order to solve the hydrothermal coordination problem through the optimal operation planning of large and nonlinear complex systems. Aiming to explore different solutions for this kind of problem, this paper suggests a comparison between the results of genetic algorithms and simulated annealing. The proposed techniques are applied in two hydrothermal test systems that are part of the Brazilian electric system, one composed by seven and other composed by fourteen hydro plants. The results show the effectiveness of the proposed techniques.
