Modelica-based parallel computing framework for power system adaptive special protection schemes

In this paper, we propose a Modelica-based parallel computing framework for adaptive special protections schemes in power systems. The use of Modelica allows for an easy implementation of both component and special protection systems and the parallel computing allows for testing and evaluating settings concurrently fast enough for real-time operation. Our framework is flexible and new component and protection models can easily be added. The framework is demonstrated using a four-area test network, inspired by the Nordic power system. We show how the framework can be used for ranking different system protection settings, based on the amount of load shedding.
