The electricity demand is continuously increasing, so a most efficient use of the current power system's capacity desired. Flexible AC Transmission Systems (FACTSs), recently developed transmission technology, are widely used to boost transfer ability long-distance line networks and enhance consistency systems. FACTS devices can lead reduced flows on heavily loaded lines, targeted bus voltage l...

When power systems are expanded and connected together with weak tie lines, the low-frequency oscillations are increased and the stability margin of the power system decreases. Therefore, when designing the transmission system to be used, it is necessary to maintain the dynamic stability of the power system, and to make sure to have the most possible stability margin. SSSC is a FACTS device con...

This work proposes a moving target defense (MTD) strategy to detect coordinated cyber-physical attacks (CCPAs) against power grids. The main idea of the proposed approach is invalidate knowledge that attackers use mask effects their physical attack by actively perturbing grid’s transmission line reactances via distributed flexible AC system (D-FACTS) devices. MTD design consists two parts. Firs...

This paper presents voltage stability in an electrical network when connected by wind generators. Due to several advantages wind energy is the growing renewable energy. Nowadays, wind energy is penetrating into the conventional power network. Due to random variations in wind speed, the output power and terminal voltage fluctuates continuously. The influence of wind generators on the power quali...

The electric power grid has evolved significantly over the past two decades in response to climate change. Increased levels of renewable energy generation, as a prominent feature this evolution, have led new congestion patterns transmission network. system is originally designed for conventional sources, with predictable flow patterns. Insufficient transfer capability congested systems results ...

Electricity demand is sharply increasing with the growing population of human beings. Due to financial, social, and political barriers, there are lots difficulties when building new thermal power plants transmission lines. To solve this problem, renewable energy sources flexible AC systems (FACTS) can operate together in a network. Renewable provide additional grid, whereas FACTS devices increa...

This paper presents a genetic algorithm based approach for solving security constrained optimal power flow problem (SCOPF) including FACTS devices. The optimal location of FACTS devices are identified using an index called overload index and the optimal values are obtained using an enhanced genetic algorithm. The optimal allocation by the proposed method optimizes the investment, taking into ac...

With the development and advancement of power electronics devices in recent years, changes in the scenario in the field of controlling and handling the power quality issues have been very effective. FACTS devices are the outstanding approach. In this manuscript,we choose one such FACTS device known as STATCOM, a powerful shunt controller, for discussing its impact and depth how to tackle the po...
