Development of dynamic test cases in OPAL-RT real-time power system simulator

The paper describes the development of the dynamic models of a number of commonly used test power systems in OPAL-RT real-time simulator environment. The process of building the dynamic test cases is described, and the challenges faced during such development are discussed. The performance of the dynamic test cases is investigated under various disturbances such as single-line-to-ground fault, line outages, step load change, and tap changing of on-load tap changers.
