چکیده
Abstract Conventional phase‐shifting transformers (PST) have been utilized for power flow control in transmission networks many years. Compared to the slow reacting PSTs, recently trending unified controllers (UPFC) enable much faster control. This paper introduces a decentralized scheme (PFCs) without need communication between PFCs. For each PFC, an influence area is defined. The line loading of lines this monitored real‐time operation and if there overloading line, feedback used mitigate line. As UPFC dependent network topology converter limit, additional measures are introduced circumvent potential critical scenarios. Supplementary also developed increase robustness simultaneous with PST. Using RMS simulation DIgSILENT PowerFactory, method validated IEEE 68‐Bus NETS/NYPS test bench network. UPFCs overlapping areas combination fast acting PST devices.

Optimal Placement of Unified Power Flow Controllers to Improve Dynamic Voltage Stability Using Power System Variable Based Voltage Stability Indices
This study examines a new approach to selecting the locations of unified power flow controllers (UPFCs) in power system networks based on a dynamic analysis of voltage stability. Power system voltage stability indices (VSIs) including the line stability index (LQP), the voltage collapse proximity indicator (VCPI), and the line stability index (Lmn) are employed to identify the most suitable loc...

High Power Multilevel Unified Power Flow Controller (UPFC) for Effective Control of Real & Reactive Power
High-voltage and power capability of multilevel converters better used for unified power-flow controller (UPFC application). The three-level neutral-point-clamped (NPC) converter allows back-to-back connection as the UPFC shunt and series converters than other multilevel topologies. In place of the pulse width-modulated (PWM) multilevel control schemes, constant dc-link voltage and balanced vol...
متن کاملPHEVs Park as Virtual Unified Power Flow Controllers
Unified power flow controllers (UPFCs) are FACTS devices which can fulfil multiple power-flow control objectives, such as the need for reactive shunt compensation, phase shifting and series compensation. However, as they are quite expensive, they are not widely used. In this paper, the potential of a plug-in hybrid electric vehicle (PHEV) in a vehicle-to-grid (V2G) mode of operation using a PHE...
