Background Modern electrical grids tend to have higher penetration of intermittent energy sources. The grid infrastructure is also more susceptible to physical damage due to increased extreme weather events. Grid operators have to run multiple power flows for different scenarios in real time to continuously monitor the system states and make necessary...

Background Trajectory sensitivity (TS) is a powerful approach to aid in dynamic security assessment (DSA). However, its practical usage has been limited so far due to concerns associated with its scalability. With a focus on increasing penetration of inverter-based resources and a long queue of pending generation interconnection requests, large-scale...

In the field of power grid analysis, particularly in distribution systems, solving the power flow problem is fundamental for grid planning and operational decision-making. Traditionally, methods rely on iterative techniques and sparse linear solvers to find solutions. However, these approaches can be computationally intensive, require careful initialization,...
