Hybrids-Simulation using EMT - And Phasor-Based Model for Converter Dominated Distribution Grid

The objective of this paper is to demonstrate a practical real-time approach for simulation of a converter dominated distribution grid. 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. In this Approach offer a tool to find the balance between calculation efficiency and simulation accuracy. The improvement on real time capability and system-usage by using this hybrid approach are demonstrated with real-time simulation results on OPAL-RT realtime simulator.
