Simulation of a Three-Phase Multilevel Unified Power Flow Controller UPFC [PDF]

Journal of Applied Sciences, 2008
This work deals with the study and simulation of Unified Power Flow Control (UPFC) at its normal and abnormal conditions. The systems are modeled and simulated using MATLAB software. Shunt inverter or Static Compensator (STATCOM) is modeled as a 3-phase multipulse converter and the series inverter or SSSC has been constructed as a 3-phase, 3-level ...

Optimal Placement and Sizing of Series and Shunt Compensation for Improving Power Systems Operation

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Power systems are complex, and power demand has constantly increased over time. Moreover, power transmission systems have a limited capacity, causing the increase in demand to be difficult to accommodate. Additional system requirements include maintaining voltages within specific values and limiting voltage drop in the lines to ensure voltage stability,

Structure and Hierarchical Control Method of Battery‐Based Hybrid Power Flow Controller

International Transactions on Electrical Energy Systems, Volume 2026, Issue 1, 2026.
This article proposes a battery‐based hybrid power flow controller (B‐HPFC), offering enhanced flexibility for power flow regulation and energy storage. First, the structure of B‐HPFC is given, where the cascaded H‐Bridge (CHB) is integrated with the phase‐shifting transformer (PST). The batteries are connected to the modules of CHB.

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.

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

INJECTION POWER UPFC MODEL FOR INCORPORATION OF UNIFIED POWER FLOW CONTROLLER IN LOAD FLOW STUDIES [PDF]

JES. Journal of Engineering Sciences, 2007
This paper is devoted to the incorporation of the s teady-state model of the unified power flow controller (UPFC) in power flow programs using a UPFC injection model. The adopted UPFC injection mo del is based on the representation of UPFC in steady-state conditio ns by two voltage sources in series with certain reactances.

Simulation study of FACTS devices based on AC-AC modular multilevel hexagonal chopper [PDF]

, 2017
This paper proposes a new range of FACTS device based on direct AC-AC conversion, where the modular multilevel AC hexagonal chopper (M2AHC) is employed. The M2AHC is operated in quasitwo-level (Q2L) mode; and the heterodyne modulation is used to decouple
