“…The application of these steps to obtain an equivalent for the future PY-AR power system is detailed in the following subsections. The final purpose of the development of dynamic equivalents of this system was to perform Hardware-In-the-Loop (HIL) tests in the Special Protection Scheme (SPS) developed to ensure safety to the operation of Paraguayan and Argentinean power systems in an interconnected condition [10], [11], [12].…”

This paper proposes an approach to aggregate nonstructured power system controllers preserving the dynamical characteristics of the original devices. The method is based on linear operations that use the frequency response of the elements, resulting in an accurate input-output description of the equivalent controller when compared to the original ones. The developed method was applied to a model of the future interconnected Paraguayan-Argentinean power system to produce a dynamic equivalent used in a real-time simulator to test the special protection scheme needed for the safe operation of the this future system. Transient and small-signal stability studies presented matching simulation results in the time domain with significantly reduced computational burden and processing time.
