Modelling and Real Time Simulation of Microgrid using Typhoon HIL

This paper presents the modeling and design of a simple microgrid consisting of two sources and two loads using a Typhoon Hardware-in-loop (HIL) simulation package with HIL402 configuration in the virtual environment. The performance of two sources on different loads is considered. The contactors are used to find the behavior of the sources on the loads. When the Source contactor is operational, two sources are supplying to two loads and when it is disconnected, two sources are supplying to a constant power load with frequency droop characteristics. The load contactor is activated by connecting it to another resistive load in parallel to the existing one. As the constant power blocks are modeled as current sources, a core coupling component is added to avoid degeneration in the circuit. The simulation signals are monitored with SCADA widgets using a wide selection of measuring and monitoring instruments.
