Hybrids-Simulation using Different Model Basis for Converter Dominated Distribution Grid

​RT Spotlight Zurich - The objective of this presentation is to demonstrate a practical real-time approach for simulation of a converter dominated distri-bution grid. To find an equilibrium between calculation efficiency and simulation accuracy, this approach suggested, use ePHASORSIM to simulate the large-scale over-layer grid in phasor-domain, and eMEGASIM for selected buses of 20kv grid in EMT-based detailed equivalent model. The improvement on real time capability and systemusage by using this hybrid ap-proach are demonstrated with real -time simulation results on OPAL-RT.
