The Stability for a Grid Connected Dg System Using Fuzzy System

Abstract

In this paper steady-state modeling of Static VAR Compensator (SVC) for power flow studies has been represented and discussed in details. Firing angle model for SVC was proposed to control the voltage at which it is connected. In same manner firing angle model for SVC is proposed with Fuzzy controller to control active power flow of the line to which TCSC is installed. The proposed models take firing angle as state variable in power flow formulation. To validate the effectiveness of the proposed models ANN algorithm was developed to solve power equations in presence of SVC. The Case studies are carried out on 9-bus test system to demonstrate the performance of the proposed models.
