|
Flexible AC Transmission System (FACTS) technology, which aims at increasing system operation flexibility, appears as an attractive alternative. FACTS controllers are included in an electrical power system to overcome operational problems. Static VAR compensator (SVC) is a shunt connected static VAR generator (or absorber) whose output is designed to draw capacitive or inductive current so as to maintain normal voltage at the bus with which the SVC is connected. SVC can be incorporated to an electrical power system using WLS state estimation algorithm. In this paper various changes made in Jacobean matrix when SVC is added. Comparison with and without SVC done with IEEE 3bus and IEEE 14bus at different locations then voltage magnitude and phase angle variations at each node determined. |
