Distributed Simulation of Power Systems using Real-time Digital Simulator

The simulation of power system behavior, especially transient behavior, helps in the analysis and planning of various power systems phenomenon. However, power systems are usually highly complex and distributed, thus system partitioning has to be used to allow for sharing resources in simulation. At Mississippi State University, researchers are developing distributed simulations of power system models using all electromagnetic transient simulator, namely RTDS. The goal is to demonstrate and assess the feasibility of both non-real-time and real-time simulations using the RTDS in a geographically distributed scenario. RTDS has the capability of sending and receiving digital data in a local area network using a special interface known as GTNET. In this work the RTDS is used in a wide area network for sending and receiving data. The different protocols and options used in the RTDS communication between power system models will be studied and analyzed.
