Variable-speed technologies have been adopted to improve the efficiency of electricity generation in wind farms. Among these technologies, doubly-fed induction generators have widely spread and their stability issues have been experienced and analysed. In recent years, permanent-magnet...

While transient stability (TST) programs can represent very large systems, they are unable to model power electronic devices in detail since they use relatively large time steps and balanced representation of the network. Electromagnetic transients (EMT) simulators, on the other hand, can model...
