【Abstract】 To effectively solve the unit optimal commitment of power system,an improved partheno genetic algorithm (IPGA) is presented. In IPGA the decimal number strings are used and the crossover operators operating between two chromosomes are repealed. It means that all of the genetic operations occur only in one chromosome, therefore, the genetic operation of IPGA is simple and more efficient, the individual in its initial population need not the property of variety and there is no "immature convergence". Comparing with traditional unit optimal commitment method,this method can manage the complicated constraints of unit optimal commitment expediently. The results of calculating examples show that IPGA is effective.更多还原
