UPFC is a versatile FACTS controller that can regulate the Power Flow through the Line by controlling its Series and shunt parameters. In shunt it is having STATCOM and in series SSSC are employed can independently control the Line Power Flow. Two Converters improves the flexibility and provide additional degree of freedom in Power System. With the application of UPFC, Transient stability of th...

We address the problem of power system restoration after a significant blackout. Prior work focus on optimization methods for finding high-quality restoration plans. Optimal solutions consist in a sequence of grid repairs and corresponding steady states. However, such approaches lack formal guarantees on the transient stability of restoration actions, a key property to avoid additional grid dam...

|Transient stability investigations consist of studying the rotor oscillations of generators (electro-mechanic oscillations, 0.1-2 Hz) after the occurrence of a fault of large amplitude, e.g. short circuit. The goal is to indicate if the generators are capable to stay synchronous after a fault has occurred. The fault duration is one of the most important factors to be determined. In fact, the s...

With increased power transfer, transient stability is increasingly important for secure operation. Transient stability evaluation of large scale power systems is an extremely intricate and highly non-linear problem. An important function of transient evaluation is to appraise the capability of the power system to withstand serious contingency in time, so that some emergencies or preventive cont...

The extensive expansion of large photovoltaic (PV) farms in power systems diminishes both system inertia and synchronizing coupling. Due to the occurrence of several faults, the power system transient stability may be damaged. However the transient stability is improved by the fast power controlling ability of the PV inverter. This paper focuses on the new application of large PV farms equipped...

The main objective of this paper is to perform transient stability analysis using the electrical power systems design and analysis software namely ETAP. The purpose of performing transient stability on the power system is to study the stability of a system under various disturbances. The stability of the power system is the ability of generators to remain in synchronisation even when subjected ...
