Transient Stability Analysis of Virtual Synchronous Generator Equipped with Quadrature-Prioritized Current Limiter

Mitigation Transformer Inrush Current Using Modified Transient Current Limiter

This study presents a modified transient current limiter (MTCL) for mitigation the inrush current of transformers. The MTCL is based on conventional transient current limiter (TCL), which, its configuration is modified to overcome the TCL drawbacks of operation. The proposed MTCL offers lower power losses and voltage/current THD during normal operation mode. It needs only one limiting reactor i...

PV-based virtual synchronous generator with variable inertia to enhance power system transient stability utilizing the energy storage system

The Photovoltaic (PV) plants are significantly different from the conventional synchronous generators in terms of physical and electrical characteristics, as it connects to the power grid through the voltage-source converters. High penetration PV in power system will bring several critical challenges to the safe operation of power grid including transient stability. To address this problem, the...

Impact of Bridge type Fault Current Limiter on Power System Transient Stability

In this paper, transient stability improvement using bridge type fault current limiter (FCL) is presented in single machine infinite bus (SMIB) system with a double circuit transmission line. Three single-phase sets of the proposed FCL are installed at the beginning of feeder. The proposed FCL inserts an inductance and a resistance in the fault current pass. The insertion inductance and resista...

Transient Stability Analysis of SMIB System Equipped with Hybrid Power Flow Controller

Recently, a novel hybrid power flow controller (HPFC) topology for FACTS was proposed. The key benefit of the new topology is that it fully utilizes existing equipment. The MATLAB/SIMULINK models of three different configurations of HPFC have been investigated for their different characteristics, by incorporating them in the SMIB system. In all the three cases, the steady state stable values of...
