lines affects their dynamics. The main example we are dealing with is a power grid that has …

Partial stability criterion for a heterogeneous power grid with hub structures

V Khramenkov, A Dmitrichev, V Nekorkin - Chaos, Solitons & Fractals, 2021 - Elsevier
One of the priority tasks in studying power grids is to find the conditions of their stable
operation. The fundamental requirement is synchronizing all the elements (generators and …

Bistability of operating modes and their switching in a three-machine power grid
