Transient Analysis of an Advanced Static Var Compensator Using Quad-Series Voltage-Source PAM Inverters.

Voltage Stability Improvement using Static Var Compensator in Power Systems

This paper investigates the effects of Static Var Compensator (SVC) on voltage stability of a power system. The functional structure for SVC built with a Thyristor Controlled Reactor (TCR) and its model are described. The model is based on representing the controller as variable impedance that changes with the firing angle of the TCR. A Power System Computer Aided Design /Electromagnetic Transi...

A New Modelling and Control Analysis of an Advanced Static Var Compensator Using a Three–level (npc) Inverter Topology

This paper presents a study of the dynamic performance analysis of an Advanced Static Var Compensator (ASVC) using a three-level voltage source inverter. The analysis is based on the modelling of the system in the d -q axis. The dynamic behaviour of the system is analysed using P-spice (Simulation Program with Integrated Circuit Emphasis) as a simulation program. Various transient simulation re...

Voltage stability index based optimal placement of Static VAR Compensator and sizing using Cuckoo Search Algorithm

This paper furnish the new Metaheuristic algorithm called Cuckoo Search Algorithm (CSA) for solving optimal power flow (OPF) problem with minimization of real power generation cost. The CSA is found to be the most efficient algorithm for solving single objective optimal power flow problems. The CSA performance is tested on IEEE 57 bus test system with real power generation cost minimization as ...
