N2 - The predictive modelling of hybrid modes is performed with the ASTRA code employing the GLF transport model in KSTAR. Fusion performance relevant to experimental values is reproduced. The NTM effects are taken into account by coupling the solver of MRE to ASTRA for computing time evolution of widths of islands, self-consistently. The effect of ECCD is also investigated. Both the (3,2) and (2,1) modes are supposed to be stable in this regime, but ECCD can improve the stabilising effect. Contradiction to the stability of the (2,1) mode calculated using fixed parameters at single time point suggests the importance of integrated simulation of NTM corporated with time-dependent transport phenomena.
