Jf. Gronquist et al., POWER OSCILLATION DAMPING CONTROL STRATEGIES FOR FACTS DEVICES USING LOCALLY MEASURABLE QUANTITIES, IEEE transactions on power systems, 10(3), 1995, pp. 1598-1605
This paper presents a way to derive power oscillation damping control
strategies for Flexible AC Transmission (FACTS) devices, and derives t
hese laws for the four major types of FACTS devices using an energy fu
nction (Lyapunov) method. All control rely only on locally measurable
information, and are independent of system topology, implying structur
al uncertainty need not affect power oscillation damping control strat
egies.
