Assessment and recommendations for the modelling of faults within power electronics based power systems

In recent years, power electronics have become a key enabling technology within electrical distribution networks, supporting the use of many other novel technologies. They also have a considerable impact though, on the configuration and operation of the electrical networks. Accurate simulations are hence required to aid the development and understanding of these networks. However, simulations using switched power electronics models can be very time consuming, and most power electronics modeling simplification techniques fail to give accurate results for specific systems-level studies. New model simplification methods must be developed in order to facilitate accurate and time efficient systems level simulations.
