Abstract:
In a deregulation electricity industry, congestion is most likely to occur and FACTS device have been proven to be very effective in mitigating this challenge. In this paper, sensitivity based analysis is used to determine the optimal place to locate series FACTs devices, the device used for the investigation is Thyristor Controlled Series Capacitor (TCSC). This approach was tested on the South East Nigeria II bus network in Power System Analysis Toolbox (PSAT), was used for the simulation of the system. the load flow results obtained showed the effectiveness of the method.
