Assessing the dynamic stability of the Slovenian power system

Transmission system operators are essential in ensuring secure and reliable operation of the modern electric power system. However, due to the steady rise of electricity consumption, the integration of new technologies such as renewable energy sources and the shift from a vertical to a horizontal structure of the electricity market, the margin of the power systems resilience to contingencies has been slowly deteriorating. In recent years, the need for real-time monitoring of power system dynamic stability has increased, because classical approaches, where only assumed worst case operating conditions and contingencies are simulated, may overlook the actual most severe operation states. In this paper a new tool is presented, that helps the
