Linear Voltage Stability Indicator (LVSI) for Optimal Placement of SVC Devices to Improve the Voltage Stability Margin in Transmission Systems

This study presents a procedure for placing static var compensators (SVC) in an EPS using the fuzzy c-means clustering technique. For this purpose, optimal power flow (OPF) is initially quantified to obtain sensitivity array of system based on Jacobian system. Then, attenuation and electrical distance matrices are estimated. Subsequently, algorithm used with estimated cluster identification criterion voltage control areas (VCAs). On other hand, minimizing installation costs SVCs conjunction linear stability index (LVSI) ideal arrangement compensators. applied each VCA created. The technique described 14-node 30-node schemes check their effectiveness. Additionally, results obtained compared Power Factory software similar studies. Finally, proposed proves be effective creation VCAs placement SVC equipment.
