This study presents an application for a series VSC (voltage source converter) in distribution grids power flow management. Series devices have been widely studied FACTS (flexible AC transmission systems), however, more recently these gained increased interest applications loading balance medium voltage grids. As the number of distributed generation (DG) units increases, increasing capacity and...

The loss minimization is a major role in Power System (PS) research. Transmission line losses in a PS can be reduced by Var compensation. After the establishment of power markets with transmission open access, the significance and use of Flexible AC Transmission Systems (FACTS) devices for manipulating line power flows to relieve congestion and maximize the overall grid operation have been incr...

The FACTS (Flexible AC Transmission System) devices have been considered as excellent controllers in a power system for better reliability and transmission capacity on a long-term and cost-effective basis. In this paper, a novel power flow controller topology is proposed for FACTS in order to improve static voltage stability characteristics and loading margin enhancement. Employing hybrid topol...

Loss minimization in power system is an important research issue. Transmission line losses in a power system can be minimized by means of reactive power compensation. The continuous demand in electric power system network has caused it to be heavily loaded leading to voltage instability. This phenomenon has also led to voltage profile depreciation below the acceptable secure limit. The signific...

The Static Synchronous Series Compensator (SSSC) is one of the recently developed Flexible AC Transmission System (FACTS) devices. In this paper, the SSSC is realized using a 48-pulse voltage source inverter. Fuzzy logic controllers are designed to operate the SSSC in the automatic power flow control mode. The parameters of the fuzzy controllers are varied widely by a suitable choice of members...

This paper presents a proposal for a new upgrade that will incorporate power electronics experiments in the electric machines lab at Oklahoma State University (both Stillwater and Tulsa campuses). We will introduce a general lab setup which includes digital data acquisition (DAQ) and virtual instrumentation. The application of 3 inverters will be discussed with our lab setup. The installation o...

This paper presents an Interior Pont Method (IPM) and variant of Particle Swarm Optimization (CFAPSO) based hybrid method to solve optimal power flow in power system incorporating Flexible AC Transmission Systems (FACTS) such as Thyristor Controlled Phase Shifter (TCPS) for minimization of multiple objectives. The proposed IPM-CFAPSO algorithm identifies the optimal values of generator active-p...

Power system engineers are currently facing challenges to increase the power transfer capabilities of existing transmission system. This is where the Flexible AC Transmission Systems (FACTS) technology comes into effect. With relatively low investment, compared to new transmission or generation facilities, the FACTS technology allows the industries to better utilize the existing transmission an...

More than one hundred countries are using wind energy due to their easy implementation, cheap energy, and high energy efficiency. Implementation of FACTS devices in Wind Energy Conversion Systems (WECS) has been dramatically improved due to cooperative and accurate performance of FACTS devices. However, dealing with wind turbine faults promptly is crucial. Short-term and long-term faults may ha...

Modern power system becomes more complex and difficult to control with the wide integration of renewable energy and flexible ac transmission systems (FACTS). In recent years many types of renewable source (Wind, solar,) and FACTS devices (SVC, STATCOM, TCSC, UPFC) integrated widely in the electricity market. Wind power industry has been developing rapidly, and high penetration of wind power int...
