45. Comparative Study of SVC-STATCOM Devices on Voltage Stability Applied on PV-Wind System

In today's technology, using static compensators to maintain stability is gaining trust every day. In this article, Static Variables Compensator (SVC) combined with a Static Synchronous Compensator (STACOM) form the ingredients of voltage stability system, more precisely to keep the voltage factor as close as possible to the unity network (1 PU). After these device’ deployment, the improved stability of the hybrid PV-Wind system efficiency is determined through the calculation of power flow and compared to the calculated power flow before the integration of these devices. The motivation for this operation is to find the contrast and evaluate the different devices’ roles in the subject system. The subject system is formed with 14 bus bars, for which their contribution to the improvement of the stability, altered by each device. As a result, and after analysis a considerable reduction of drops of the voltage of the bus bar yielding appreciated voltage control.
