The main objective of this paper is to find the optimal location and control parameters settings of Unified Power Flow Controller (UPFC) with regard to power loss minimization. The proposed algorithm is based on steady state power injection model of UPFC. In this paper, two Evolutionary optimization techniques, namely Differential Evolution Algorithm (DE) and Genetic Algorithm (GA) are employed...

The use of the supplementary controllers of a unified power flow controller (UPFC) to damp low frequency oscillations in a weakly connected system is investigated. The potential of the UPFC supplementary controllers to enhance the dynamic stability is evaluated by measuring the electromechanical controllability through singular value decomposition (SVD) analysis. Individual designs of the UPFC ...

برخی از گونه ‏های زنبور تریکوگراما، دارای نوعی همزیستی با باکتری Wolbachia هستندکه باعث القاء بکرماده ‏زایی در آنها می‏شود. جمعیت‌هایی این پارازیتوئید تخم آفات که نتاج ماده بیشتری تولید می‌کنند، می‌توانند بالقوه توان بالاتری برخوردار باشند. پس شناسایی یک جمعیت بومی آلوده به ولباکیا Trichogramma brassicae، بررسی‏ هایی منظور ارزیابی توانایی‌های تک‏جنسی (A) قیاس جمعیت‌‏های دوجنسی طبیعی (B) و تغذیه...

This article presents a novel configuration for unified power flow controller (UPFC) comprising modular multilevel cascaded converter (MMCC) with full-bridge inverter. The MMCC has one end of each phase-leg shunt-connected to the transmission line. other connects in parallel primary terminals series line transformer, and ac output dc–ac submodules are flying capacitor converters. UPFC is compar...

This study presents a study of the application of a Unified Power Flow Controller (UPFC) to control power transmission, generator terminals voltage and better damping of Low Frequency Oscillation (LFO) in Single-Machine Infinite-Bus (SMIB) power system. The UPFC integrates properties of both shunt and series compensations and can effectively alter power system parameters in a way that increases...

We deal with the effect of Unified Power Flow Controller UPFC installation on the objective function of an electricity market. Also this paper proposes a Novel UPFC modelling in OPF which facilities the consideration of the impact of four factors on power market. These include the series transformer impedance addition, the shunt reactive power injection, the in-phase component of the series vol...

In the present scenario of the power system the main issue is the voltage stability enhancement which plays an important role in the complex network. This paper introduces the forthcoming technology employing the integration of Flexible AC transmission System (FACTS) device in to the system. Betwixt of all the FACTS devices this paper mainly rivet on Unified Power Flow Controller (UPFC). This i...
