Abstract
In this paper a diploid genotype based Genetic Algorithm (GA) is applied to solve the short-term scheduling of hydrothermal systems. The proposed gene tic algorithm uses a pair of binary strings with the same length to represe nt a solution to the problem, Crossover operator is tarried out by means of separating and recombining technique, which is of the same effect of that of uniform crossover. Dominance mechanism in the algorithm is realized by a simple Boolean algebra calculation. Simulation results show that the propo sed algorithm has a strong ability to maintain gene diversity in a limited population due to the diploid chromosomal structure in accompany with the d ominance mechanism. This ability improves the overall performance and avoid s premature convergence, The model can concurrently tackle the requirements of power balance, water balance and water traveling time between cascaded power stations, which are more difficult for other approaches to manage. Se veral examples are used to verily the validity of the algoritlun.
