Assessment of the Effectiveness of Two Coordinated Systems: SVC-PSS and STATCOM-PSS for Improving Transient Stability of Power System

Abstract

Abstract-The power system stabilizer (PSS) is a control device provides a maximum power transfer and optimal power system stability. PSS has been widely used to damp electromechanical oscillations that occur in power systems due to disturbances. If no adequate damping is available, the oscillation will increase result in instability case. Shunt static var compensator (SVC) and Static Synchronous Compensator (STATCOM) is also used to improve system stability. This paper focus on the significant of SVC-PSS and STATCOM-PSS to improve the transient stability of power system in various abnormal condition. This paper shows the simulation result of model for different fault condition with PSS and without PSS, with SVC and without SVC, with STATCOM and without STATCOM, and show how the Statcom and SVC help to improve the stability when PSS is fail to maintain the stability.

Improving Voltage Stability of Electrical Power System by Optimal Location of FACTS Devices Using an Evolutionary Method

“…This new technology participates in the enhancement of many operations in the EN system such as controlling active and reactive power flow, minimizing active losses in the transmission line and improving technical performance in power system. Indeed, the manner to set up this FACTS device technology with suitable locations and parameters is the actual subject of many research studies; in this context, several research papers have been published and the results have been presented in different international journals [5,7,16]. uses power electronics to control power flow on electrical networks.…”
