The recent advent of the phasor measurement unit (PMU) and their associated networks has revealed that forced oscillations are a common occurrence in synchronized power systems. Forced oscillations are not be confused with electromechanical oscillations. Forced oscillations are typically caused by some rouge input driving the system into a sustained oscillation. An example is an ill-operating power-plant...
Synchronous power systems often experience two types of oscillatory responses: natural and forced. Natural oscillations are a transient response characterized by the electromechanical oscillation modes. If one or more of these modes are undamped, a sustained oscillation occurs with the system in a near unstable condition. Alternatively, forced oscillations are typically caused by some rouge input...
