In recent years, the complexity of power systems and hardware interfaces have been growing, making Hardware-In-the-Loop (HIL) simulation more difficult for systems with different data exchange methods. One of the challenges in simulating complex power systems is to guarantee faultless communication and high data throughput between components. Focus of research in this work is the concept of expanding the data exchange capabilities for the Real Time Digital Simulator (RTDS), because extensive simulation studies are of great importance. The theoretical aspects of powerful new interfacing...
