OPF With SVC and UPFC Modeling for Longitudinal Systems

IEEE Transactions on Power Systems, 2004
This paper presents a formulation of the Optimal Power Flow problem with an explicit modeling of Static Var Compensator (SVC) and Unified Power Flow Controller (UPFC) devices. The optimization problem is solved by using Sequential Quadratic Programming, where two convergence criteria and four different methods are studied to solve the quadratic ...

Stability Analysis of a Grid‐Connected DFIG Wind Farm Using Static VAR Compensator

Journal of Electrical and Computer Engineering, Volume 2026, Issue 1, 2026.
The integration of wind farms has greatly impacted the stability and performance of power systems. This is primarily due to the intermittent nature of wind energy, which requires advanced control strategies and robust grid‐integration techniques. This paper employs a Static VAR Compensator (SVC) equipped with a proportional integral (PI) controller to ...

The impact of demand response programs on UPFC placement

TURKISH JOURNAL OF ELECTRICAL ENGINEERING & COMPUTER SCIENCES, 2019
Demand response (DR) and flexible AC transmission system (FACTS) devices can be effectively used for congestion management in power transmission systems. However, demand response program (DRP) implementation can itself affect the optimum location of FACTS devices, which is one of the main issues in power system planning.

Wide‐area damping control in renewable integrated power systems: A review on recent achievements and new challenges

Energy Conversion and Economics, Volume 6, Issue 6, Page 341-358, December 2025.
Abstract Low‐frequency oscillations (LFOs) remain a major obstacle to maintaining stable dynamic performance in power systems with high levels of renewable energy integration. In particular, inter‐area LFOs have emerged as a critical concern in large, interconnected grids.

Direct Voltage Control in Grids With Intermittent Sources Using UPFC

Eletrônica de Potência, 2014
This paper proposes the use of a circuit with topology similar to an UPFC for direct voltage control in electric grids with highly intermittent generation sources such as wind generators. The variable characteristics of these sources strongly affect the

A Systematic Literature Review on Auction Mechanisms: Insights From the Last Decade and Future Directions

Journal of Economic Surveys, Volume 39, Issue 5, Page 1971-1998, December 2025.
ABSTRACT This study reports the results of a systematic literature review on auctions mechanism. Auctions are a very popular practice employed in many fields but does not exist a research that investigates the use of auctions under a cross‐disciplinary approach. This work is focused on analyzing which are the areas where auctions are mostly adopted and

Optimal Location and Sizing of Static Var Compensator (SVC) to Improve Voltage Profile in Distribution Network

Engineering Reports, Volume 7, Issue 10, October 2025.
Optimized placement of SVC in a 33‐bus distribution system improves voltage profile, increasing the voltage profile from 94.69% to 97.90%, ensuring voltages remain within acceptable limits (0.95–1.05 p.u.) using optimal capacitor sizing and location, enhancing system reliability and power quality.
