Abstract

Electromechanical dynamics are not only an issue on transmission system level. They also take place in distribution grids, in particular in islanded distribution grids, as long as there are at least two elements that form an oscillatory interaction with respect to their state variables. Considering this aspect is a key factor for developing restoration schemes, which focus on restoring electrical islands on the distribution level after a wide area blackout. This work answers the question of how the dynamic behavior of distribution islands differ from the well-known transmission system characteristic. Furthermore the necessity of migrating protection requirements like dynamic related short fault-clearing times or the implementation of power swing blocking functions on the protection relays in distribution systems is discussed.
