Modeling of Power Systems for Small Signal Stability Analysis with FACTS
Small signal stability in a power system is the ability of the system to ascertain a stable operating condition following a small perturbation around its operating equilibrium. Power system disturbances can be broadly classified into two categories; large and small. Disturbances such as generation tripping, load outage, faults etc have severe influences on the system operation. These are large disturbances and the dynamic response and the stability conditions of the system are assessed within the standard framework of transient stability analysis and control. The system is modeled as a non-linear dynamic process. A large number of references dealing with this problem exist in power engineering literature -. Essentially the researchers have applied non-linear system theories and simulations to establish a clear understanding of the dynamic behavior of power system under such conditions. Effective tools to analyze and devise various non-linear control strategies are now in place.
