Power systems exhibit various modes of oscillation due to interactions among system components. Many of the oscillations are due to synchronous machine rotors swinging relative to each other. Controllable Series Devices (CSD), i.e. series connected Flexible AC Transmission Systems (FACTS) devices, such as Unified Power Flow Controller (UPFC), Controllable Series Capacitor (CSC) and Quadrature B...

The stability and security improvements of the grid-connected to wind energy conversion system (WECS) can be made by optimizing placement a flexible alternating current transmission (FACTS). This study discusses optimal one type WECS, namely doubly-fed induction generator (DFIG) with series shunt-FACTS control device called unified power flow controller (UPFC). DFIG UPFC connected grid dynamic ...

Long distance AC transmission is often subject to stability problems, which limits the transmission Capability. Large interconnected power systems often suffer from weakly damped swings between synchronous generators and subsystems. This paper studies the comparative performance of SSSC and UPFC for the improvement of transient stability and damping of power swings of a multi-machine power syst...

No one denies the importance of renewable energy sources in modern power systems terms sustainability and environmental conservation. However, due to their reliance on change, they are unreliable systems. This paper uses a Unified Power Flow Controller (UPFC) enhance reliability performance grid-tied system consists two sources, namely photovoltaic cells (PV) wind turbines (WTs). The UPFC was s...

Cascading overload failures occurred in power systems due to higher penetration of renewable energy resources (RERs), which causes uncertainty a grid. To overcome these cascading failures, proper assessment the form load flow balancing and transients stability is required integrated grids (RIPGs). This problem becomes more critical occurrence multiple intervals faults interconnected RIPGs, trip...

In order to eliminate active and reactive power losses in the system, this paper proposes TOPSIS DE algorithm for determining best location parameter settings Unified Power Flow Controller (UPFC). To mitigate losses, UPFC allocation can be achieved by re-dispatching load flows systems. The cost of incorporating into system. As a consequence, proposed objective feature was created address proble...

FACTS technology opens up new opportunity for operation and control of power system. Out of the various FACTS devices (viz-TCSC, TCPST, UPFC etc.), the right choices for the maximization of power flow in power system network demands attention which helps to achieve the active power flow up to their line limits without any constraint violation and with optimal investment on FACTS devices. In thi...
