The mathematic model of unit optimized combination is established. The method of genetic algorithm (GA) is presented based on the binary coding and real coding. The problem is decomposed into two aspects including state combinations and load distributions of units. The result of calculation shows that the advantage of GA is with faster speed and better results, GA is viable and efficient for unit optimized combination.
