Environmental/economic dispatch, continuous parameter genetic algorithm,


This paper presents an investigation of environmental and economic dispatch problem considering a power plant composed of six generators with transmission losses using Genetic algorithm (GA). In optimisation, GAs have some well-known advantages and disadvantages. The various methods were applied as economic dispatch problem with transmission capacity constraints in literature. In this study, a similar investigation for environmental emission (NOx) and economic dispatch is considered and investigated using Continuous Parameter Genetic Algorithm, which is know to be superior for real numbers compared to simple GA. Although the computing time of GA is larger than other method, global minimum for environmental and economic dispatch problem is obtained.
