The validation of power system dynamic simulation with genetic algorithm

this paper studies the validation of power system dynamic simulation, and the method of correcting parameters. Based on acquiring the static and dynamic data, from the angle of load model, the simulation accuracy with some uncertain model parameters is analyzed, and the uncertain parameters are corrected using the post-fault dynamic data contrarily. According to the characteristics of parameter correction and transient calculation, this paper chooses genetic algorithm with strong global search ability. Finally the simulation in IEEE-39 system is completed in this paper. The load proportion is chosen as the inaccurate parameters, and the simulation of correcting two load proportions is done accordingly. Good results are achieved.
