Determination of the Thevenin equivalent in power grids using real records based on short circuit power

open access: yesIET Generation, Transmission & Distribution, 2021
In recent years, methods for loadability determination based on real‐time measurements have been proposed for long‐term voltage stability scenarios. One of these methods corresponds to the reduction of the complete system into a basic Thevenin equivalent

Coalition cascades: The politics of tipping points in clean energy transitions

open access: yesPolicy Studies Journal, Volume 51, Issue 4, Page 715-739, November 2023., 2023
Abstract Policy change often involves multiple policy subsystems, as in the case of clean energy transitions. We argue that trans‐subsystem policy feedback is a central dynamic in policy change across subsystems. Policy in one subsystem creates benefits/costs and/or learning effects that mobilize actors for policy change in another subsystem, resulting
