Less is More: Real-time Failure Localization in Power Systems [PDF]

, 2019
Cascading failures in power systems exhibit non-local propagation patterns which make the analysis and mitigation of failures difficult. In this work, we propose a distributed control framework inspired by the recently proposed concepts of unified ...

Transformer‐less unified power flow controller in medium voltage distribution networks

IET Generation, Transmission & Distribution, 2023
A transformer‐less unified power flow controller (UPFC) is a power electronic device consisting of series and shunt voltage source converters (VSCs) that are not connected to a common DC bus.

Transient analysis of a unified power flow controller and its application to design of the DC-link capacitor [PDF]

, 2001
This paper presents a transient analysis of a unified power flow controller (UPFC), and design of capacitance of the dc-link capacitor based on that analysis. Active power flowing out of the series device in transient states is theoretically discussed to

Design of Fault Protection Stra for Unified Power Flow Controller in Distribution Networks

Energies
The capacity of traditional distribution networks is limited. After large-scale distributed power sources are connected, it is difficult to consume them at the same voltage level, which can lead to transformer reverse overloading and voltage limit ...
