Damping of Electro-Mechanical Oscillations in a Multimachine System by Direct Load Control
(1997) In IEEE Transactions on Power Systems 12(4). p.1604-1609- Abstract
- Utility controlled customer loads as actuators
present new possibilities for power system control. The use of
active loads controlled by local bus frequency is proposed for
damping of electro-mechanical oscillations. The viability of
the idea is studied for one load in a three machine system
with a meshed network. Active power mode controllability
and phase angle mode observability are determined from the
eigenvectors of a differential algebraic description of the
uncontrolled system. The geographical variations in the entire
network of controllability and observability are shown to be
identical. It is presented graphically on a 3D-view of... (More) - Utility controlled customer loads as actuators

analog is introduced that explains this. Time simulations
