| Abstract: | In the present paper,we introduce a class of three step hybrid formula of order 4 (RTHYB4) for real time simulation.Theoretical analyses and numerical experiments indicate that for fourth order methods,the local accuracy and stability of RTHYB4 methods are superior to that of traditional Adams Bashforth method (RTAB4) and modified fourth order Adans Bashforth Moulton Predictor corrector method(RTABM4).From the point of view of weak stability characteristic and computational accuracy,RTHYB4 methods are clearly to be preferred. |
