Linear response theory of power grids with correlated multi-node fluctuations — •mehrnaz anvari, anton plietzsch, and frank hellmann — Potsdam Institute for Climate Impact Research

Modern societies highly depend on electricity supply via power grids. Without electricity, people do not have access to food, transportation, medical treatment and so on. Moreover, in an extended outage the security of a community can be in danger. Therefore, stability of the power grid has highest priority. For that, the balance between the energy consumption and energy production should be provided. Recently the ongoing energy transition towards renewable generation fundamentally changes the conditions for the operation of the power system. The variable renewable energies, i.e. wind and solar are known as the sources of fluctuations, which can affect the stability of the power grid frequency. In previous works, linear response theory has been shown to be a powerful tool to study the impact of power fluctuations on frequency stability in complex power grid networks. However, so far this response theory has only be developed for single node fluctuations, while real power grids are subjected to fluctuations at multiple nodes. Employing the same theoretical technique, we therefore investigate the influence of the multi-node fluctuations in the power grid, when there exists spatial correlation between the fluctuating nodes.
