Modeling of a Reciprocating Engine-Generator Set for Controller Hardware in the Loop Testing of Island Microgrid Control Systems

This paper demonstrates the modeling of a real engine-generator set based on manufacturer data for use in controller hardware in the loop testing of microgrid control systems. The simulation environment used is RTDS Technologies’ real time digital simulator using PB5 cards. In addition, this paper provides detail on integration of a Woodward easYgen controller with the simulator IO for control of the simulated engine-generator set. Testing of the developed model is performed to validate the standard parameters of the synchronous generator and the dynamic performance of the engine-generator set during starting, load step change, and stopping. The result of this investigation is an engine-generator set model that exhibits the characteristics of real equipment and may be used in the validation of controller hardware and software for the de-risking of microgrid control systems.
