PV/QV Curve based Optimal Placement of Static Var System in Power Network using DigSilent Power Factory

摘要

Due to several blackouts around the globe, the voltage stability of system becomes an important factor for stable and reliable operation of power system. FACTS devices can provide reactive power to loads when loading increases. In this paper, static voltage stability assessment techniques, i.e., PV/QV curve has been utilized for identifications of optimal locations for static var compensator (SVS). PV/ QV Curve are the conventional methods provide VSM and PSM for the system. For validation of the method, IEEE 14 bus network is used. All studies have been simulated in DigSilent Power Factory (2018). This paper gives better result for the system stability.
