Large number of contracted power exchanges among sellers and purchasers, in a deregulated market causes transmission line congestion. Congestion lines undermines the security economy networks. Flexible AC system (FACTS) devices are introduced at appropriate spots to change flow order keep within their capability. In this work, most commonly used unified controller (UPFC) is proposed for achieve...

<span id="docs-internal-guid-a50ef6a8-7fff-b6d7-8e58-d434be6097d4"><span>This paper proposes a novel approach based on the NSCE (elitist non dominated sorting cross entropy), for optimization of location and size flexible AC transmission system device (FACTS) namely: unified power flow controller (UPFC) to achieve optimal reactive (ORPF). In present work, main objective is minimize ...

In recent years, grid-connected photovoltaic (PV) power generations have become the most extensively used energy resource among other types of renewable energies. Increasing integration PV sources into network and their dynamic performances under fault conditions is an important issue for grid code requirements. this paper, a source as unified interphase controller (UIPC) to enhance low voltage...

Incremental industrialization and urbanization is the cause of enhanced energy use as it increases building new lines more inductive loads. As a result, transmission system losses increased, magnitudes voltage profile values deviated from stated value, resulting in increased cost active power generation. To mitigate these issues, adequate reactive compensation line bus systems should be done. R...

Abstract To mitigate the impacts of voltage sag, a hybrid power flow controller (HPFC) finds spot between sending and receiving terminals. This research work deals with comparison four bus systems employing UPFC HPFC. Simulation is done for 4 system using The outcomes are associated respect to voltage, active Reactive power. exemplifies grander enactment HPFC controlled compared system.
