According to the , characterist ics of practical pow er system s, such as the str ong ; nonlinearity, dynamic pro cess and etc. , the learning algor ithm s , ; , are improved : the offline iterative learning is f irstly modif ied , into the o nline equal per iodical learning, and then into the on line unequal per iodical lear ning. By changing the objective func , tion def ined in a continuous set into a function in a po int , the in : , creasing lear ning can be online. In order to make the learning , algorithm s process satisf ied eff ect iveness and can learn under , large disturbances of the system , the nonlinear ity of the system is used in the learning algorithm s.
