The genetic algorithm for the economic dispatch of loads among generators

This paper describe the mechanism and the characteristics of the Genetic Algotithm(GA). Since the power system is non-linear and the economic dispatch among hydro and thermal generators is difficult to regulate, the GA is introduced to solve the problems. The normal steps of the calculation with the GA are also listed in this paper. The calculation of he economic dispatch in a three-generator system proves the efficiency of me GA. The calculation result shows that the GA does not require the continuity of the objective function and the existence of its derivative. This characteristic makes it very fit for the optimal calculation of the power system. Furthermore, the calculation with the GA does not need to solve the regularity equations, which are not easy to solve in the economic dispatch among hydro and thermal. generators.
