Stability analysis of the OSMOSE scenarios: main findings, problems, and solutions adopted

This paper presents the main findings, problems encountered, and solutions regarding the dynamic stability of future network operation scenarios in the presence of a high amount of clean, converter-based energy sources (renewables, storage, etc.) as studied within the OSMOSE European project. This study has been carried out on a portion of the Italian transmission grid where the most recent and innovative flexibility services have been implemented to preserve the dynamic stability for the scenarios selected. The most typical and critical generation/demand conditions have been recreated on the Sicilian grid for 2030 and checked. This research proves that in the future, different services, like synthetic inertia from renewable energy sources, flexible demand response, or reactive power provision from static converters, must be taken into account to preserve system stability as traditional generators are progressively phased out.
