Abstract
Unlike the past, nearly every power system in the world today contains a large number of power electronic based devices. This makes today’s power systems more complex. The dynamics of power electronic based devices are heavily dependent on their controls. Therefore, accurate modelling of these devices and studying the behaviour of the integrated system have become important. There is an increased tendency by network owners to use RTDS and control replicas to study their systems. Currently, we are developing an integrated AC network model of a large power system which is planned to be connected to multiple HVDC control replicas. This presentation will discuss the benefit to the network owners of having a detailed AC system model, and the high level methodology and the challenges faced in developing such a model.
