in this paper, we present a new method to determine the optimal location and parameter settings of unifiedpower flow controller (upfc) for removing voltage violations and transmission lines overloading. upfc isconsidered as the most powerful member of the facts devices, that it can control shunt and series power flow.this option gives to upfc the power to control the voltage profile and transmi...

In this Project we are going to utilize The (upfc) is the most adaptable among an assortment of AC transmission framework (FACTS) gadgets, which can be utilized for power stream control, improvement transient dependability, damping motions and voltage guideline. paper, propose another PI based methodology dynamic control UPFC. With new methodology, not just responsive force yet in addition acco...

This paper presents the transient stability assessment of TCPST, UPFC and TCSC. The control laws based on few assumptions were applied and have been found to be effective for power oscillation damping for large and small signals. The bang-bang control strategy is used for IPFC in which the injected voltage magnitudes were kept constant and only one of voltage angles was varied. The results of t...

In this paper the authors propose a Genetic Algorithm (GA) to determine the operating point of a Unified Power Flow Controller (UPFC) for simultaneous solving of static security and dynamic stability problems. In particular, the interest is focused on damping of the electromechanical oscillations. The proposed algorithm is based on genetic mutation operator and it acts directly on the control p...

This paper presents a method for designing of proportional-integral-derivative (PID) controller based on unified power flow controller (UPFC) using chaotic harmony search algorithm (CHS) for damping of low frequency oscillations (LFO) in a power system. The main aim of this paper, optimization of selected gains with the time domainbased objective function which is solved by chaotic harmony sear...

This paper presents, “Performance Analysis of power flow control through FACTS Devices in Power System. In a power system network consisting of generators, transmission lines, transformers and load etc., STATCOM, SVC and UPFC are applied between two buses separately and their effects are analyzed as par applied system conditions. Power flow between different buses and voltage regulation of abov...
