Abstract Solar storms impact electrical power grids by causing quasi‐DC neutral point currents in transformers. These currents lead to half‐cycle saturation as well as other related and unwanted effects in the grid. To reduce the effect of these

Abstract This paper examines how the combined use of hydro governors and a wide‐area damping controller (WADC) can improve the damping of inter‐area oscillations in power systems. Such oscillations can endanger the stability of power grids, thus
