This presentation focuses on the development of an RTDS platform for HIL testing of an Energy Management System (EMS) at Shell Technology Center Houston (STCH). STCH is equipped with a microgrid testing facility with hundreds of kilowatts in capacity where an RTDS platform is also utilized to enable HIL testing of various control systems before they are installed and tested with the actual equipment in the microgrid facility. The power system of the microgrid test facility is modeled in RTDS where the modeled system mimics the capabilities of the equipment at the facility. The model includes battery storage systems, generators, PV systems, loads and switching devices. The performance of the EMS in meeting its defined objectives for controlling the microgrid and its assets will be tested and validated using the HIL testbed. As a step before the HIL testing, a base version of the EMS logic was also simulated in RTDS to validate the performance of the DER models developed in RTDS for various expected microgrid functions. To achieve that objective, user defined blocks in RSCAD were used in a unique way to effectively simulate target EMS functions and enable seamless transitions between different modes.
