Combined Transmission and Distribution State-Estimation for Future Electric Grids

no code implementations14 May 2021 Amritanshu Pandey, Shimiao Li, Larry Pileggi

Instead, a more distributed yet coordinated approach for grid operation and control will emerge that models and analyzes the grid with a larger footprint and deeper hierarchy to unify control of disparate T&D grid resources under a common framework.

Fast AC Steady-State Power Grid Simulation and Optimization Using Prior Knowledge

no code implementations17 Mar 2021 Aayushya Agarwal, Amritanshu Pandey, Larry Pileggi
