Enhancement of system performance and static security through an optimal placement of SVC

Abstract

The paper focuses on enhancement of system static security and to enhance the system performance under network contingencies through an optimal placement and optimal setting of static var compensator (SVC). The goal of the methodology developed is to alleviate/eliminate overloads on the transmission lines and to maintain the voltages at all load buses within their specified limits through an optimal placement and optimal setting of SVC under different network contingencies. The optimal location of SVC is identified by a new index called single contingency voltage sensitivity (SCVS) index. Finally the optimal setting of SVC is obtained to enhance the power system performance under network contingencies. This premise is attested on 6-bus system to show the effectiveness of the method.
