Studying Impact of Unified Power Flow Controller on improve transient stability by Improved Harmony Search Algorithm
Main contribution of this work is improving transient stability by installing Flexible AC Transmission System (FACTS) in power systems. For do this, Unified Power Flow Controller (UPFC) has been selected. Also a novel structure has been suggested to improve classic Harmony Search algorithm and suggested improved Harmony Search (iHS) algorithm. This algorithm has been used to obtain UPFC paramet...

متن کاملGlobal Power System Control Using a Unified Power Flow Controller
This paper explores the use of a Unified Power Flow Controller (UPFC) for global power system control. Coordinated control schemes are assigned to the UPFC, Power System Stabilizer (PSS) and generator excitation to maintain transient stability and voltage stability following a disturbance. The extension to use of UPFC in damping inter-area oscillation is also considered. Under the proposed coor...
متن کاملImprove dynamic performance of fixed speed wind turbines using unified power flow controller (UPFC) and fractional order controller (FOC)
Wind powers are very unstable in voltage fluctuations, especially in short circuit error and sharp and sudden voltage drops, which one of its main reasons is the use of induction generators in these power plants and thus need to reactive power and high magnetizing current. To improve the ride_through voltage from WECS in error conditions and damping the oscillations of the induction generator r...
متن کاملPower Flow and Modal Analysis of a Power System Including Unified Power Flow Controller
Abstract—The Flexible AC Transmission System (FACTS) technology is a new advanced solution that increases the reliability and provides more flexibility, controllability, and stability of a power system. The Unified Power Flow Controller (UPFC), as the most versatile FACTS device for regulating power flow, is able to control respectively transmission line real power, reactive power, and node vol...
