Optimal Power Flow with Power Flow Routers [PDF]

, 2017
Power flow routing is an emerging control paradigm for the dynamic control of electric power flows. In this paper, we propose a generic model of a power flow router (PFR) and incorporate it into the optimal power flow (OPF) problem.

Analysis of reactive power loadability and management of flexible alternating current transmission system devices in a distribution grid using whale optimization algorithm

IET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.
This paper suggests the optimal placement of different flexible alternating current transmission system (FACTS) devices using various metaheuristic methods associated with effective cost management in the distribution network. The outcomes show that the proposed WOA technique generates more upshot than any other evolutionary algorithms in cost ...

Hopf Bifurcation Control of Subsynchronous Resonance Utilizing UPFC

Engineering, Technology & Applied Science Research, 2017
The use of a unified power flow controller (UPFC) to control the bifurcations of a subsynchronous resonance (SSR) in a multi-machine power system is introduced in this study. UPFC is one of the flexible AC transmission systems (FACTS) where a voltage source converter (VSC) is used based on gate-turn-off (GTO) thyristor valve technology.
