Hierarchical Graph Neural Network for Probabilistic Power Flow with Grid Topology Contingencies

Jinbao Wang, Jun Liu, Shiliang Zhang +4

Data-driven surrogates reduce the nonlinear solves required for probabilistic power flow (PPF), but models tied to a fixed bus--branch graph often generalize poorly when outages ch…

Finding the evolutionary link between ULIRGs and radio galaxies

Ayisha Fida, Sumana Nandi, Mousumi Das +4

Ultraluminous infrared galaxies (ULIRGs) are the remnants of the major mergers of gas-rich galaxies. They are dusty systems and are extremely luminous in the infrared. Both starbur…
