In this study, modifications are proposed to the state‐of‐the‐art positive sequence generic converter model in order to capture the small‐signal and large‐signal oscillatory instabilities associated with converters interfaced at low short circuit locations. The performance of the positive sequence model is validated against detailed electromagnetic simulations to lend confidence in this proposed model. Additionally, validation of performance of the model against observed field measurements is also carried out.
