Query: Transient Stability of Droop-Controlled Inverter Networks with Operating
  Constraints   Due to the rise of distributed energy resources, the control of networks of
grid-forming inverters is now a pressing issue for power system operation.
Droop control is a popular control strategy in the literature for frequency
control of these inverters. In this paper, we analyze transient stability in
droop-controlled inverter networks that are subject to multiple operating
constraints. Using a physically-meaningful Lyapunov-like function, we provide
two sets of criteria (one mathematical and one computational) to certify that a
post-fault trajectory achieves frequency synchronization while respecting
operating constraints. We show how to obtain less-conservative transient
stability conditions by incorporating information from loop flows, i.e., net
flows of active power around cycles in the network. Finally, we use these
conditions to quantify the scale of parameter disturbances to which the network
is robust. We illustrate our results with numerical case studies of the IEEE
24-bus system.
