Improvement of Power System Security under Network Contingency with Static VAR Compensator

SVC is incorporated in Newton Raphson method in which Power Flow Solution is a solution of the network under normal operation as well as network contingency, the model of SVC i.e. SVC Susceptance Model is discussed. Newton Raphson Power flow method has been developed for the steady behavior of large complex power systems, it allows the study of power flow under abnormal conditions as well as normal conditions. It is shown that how the system power losses are decreased after incorporating the SVC in this model. It is also shown that how the SVC is useful in network contingency. The results are generated for 5-Bus system.
