The interconnected European power system is evolving due to the new extensions and to the systematic integrationof Power Park Modules, i.e., unit or ensemble of units generation electricity (Renewable Energy (RE), Distributed Generation(DG), etc), which is connected to the grid by power electronicsand FACTS (STATCOM, HVDC,...). As a consequence, theincrease of the size and the emergence of the new oscillatorymodes which involve distant dynamic devices, i.e., of couplingmodes (modes associated to generator/turbine inertia, and modesassociated to Power Park Modules), and of modes related tovarious regulations. In this paper, a full scan of Europeanpower system is given. An exhaustive method that determinesall oscillatory modes independently of the system’s order, of thetopology and without a priori knowledge about the system, isused. The exhaustive method is fully analytic. Indeed, it is basedonly on the state-space realisation of any given power system anddoes not require operator manipulation like dynamic simulations.To this end, we quantify and analyse the interaction betweenthe different inputs/outputs of a given system. This leads tothe identification of classes of coupled dynamic devices of thepower system. Next, starting from a reduced number of classes,a selective modal analysis method is applied to each class toput into evidence a good approximation of all oscillatory modes.Finally, a complete classification of the oscillatory modes foundat the previous stage is provided in terms of the types (interarea, electrical, ...) and their characteristics (oscillation frequency,damping, participation, ...). 2900 oscillatory modes were foundfor the studied model of the European system
