In emerging power systems, enlarged communication often lead to the situations where the structure no longer remains in secure operating region. The flexible Ac transmission system (FACTS) controllers can take part in an important role in the power system security enhancement. However, due to high capital investment, it is necessary to locate these controllers optimally in the power system. Sta...

In some decades, the demand for electrical power has increased but the generation and transmission remained limited due to limited resources and environmental restrictions. The increased demand for electrical power has also increased the complexity in the transmission system. It resulted in the form of the question of stability of power system. Here the stability of power system with possible m...

This paper presents the application of neural networks for controlling the static synchronous compensator (StatCom) device. The primary duty of the StatCom is the regulation of the AC bus bar voltage where the device is connected. Additionally, a secondary task may be added to such device for obtaining a positive interaction with other controllers in order to mitigate low frequency oscillations...
