An increased penetration of distributed energy sources in Europe causes challenges in the power system operation. One of these is the so-called 50.2 Hz issue-A threat to frequency stability due to disconnection of a large amount of distributed sources especially photovoltaic modules at the same time. This paper analyzes the frequency stability of the continental Europe synchronous area fromthe above-mentioned perspective using two dynamic models: Single-node and multinode. The influence of the system parameters (such as inertia and load) is demonstrated using the single-node model. The influence of local and interarea frequency oscillations on renewable energy sources disconnections is analyzed using the multinode model.
