The problem regarding the optimal placement and sizing of different FACTS (flexible alternating current transmission systems) in electrical distribution networks is addressed this research by applying a master–slave optimization approach. analyzed correspond to unified power flow controller (UPFC), thyristor-controlled shunt compensator (TCSC, also known as thyristor switched capacitor, or TSC)...

For the improvement of transient stability the general methods adopted are fast acting exciters, circuit breakers and reduction in system transfer reactance. The modern trend is to employ FACTS devices in the existing system for effective utilization of existing transmission resources. These FACTS devices contribute to power flow improvement besides they extend their services in transient stabi...

The power flow dynamics resulting from transmission lines charging has the potential to create nomadic congestion points, in a distribution that does not meet requirements of economic optimality. In this context, allocation Thyristor Controlled Series Compensator (TCSC) plays key role mitigating these congestions. However, number possible options for allocating compensator large porter system a...

Algorithm (GA) approach to tune the parameters of a Thyristor Controlled Series Compensator (TCSC), for power system stability improvement. Pareto method type of selection is used in the present multi-objective GA approach, which gives a set of solutions from which the best one can be chosen according to the requirements and needs. The design problem of TCSC controller is formulated as a parame...
