Transmission Congestion Mitigation with Series Controller FACTS

Transmission congestion is a serious issue in transmission networks. In the PSAT MATLAB environment, this article suggested an NR (Newton Rapshon) based algorithm for tackling transmission congestion problems.NR based evolutionary technique is used for optimum co-ordination of series controllers with imaginary power sources present in transmission network. In this article author evaluate voltage stability, real power loss reduction, and running cost by using power flow. Transmission loss magnifies the total system running cost. It also manages the improvement of VAR power because its optimization is a huge problem in transmission system. The PV curve provides a voltage collapse point and finds the location of weak bus. TCSC (Thyristor controlled series capacitors) and SSSC (static synchronous series compensator) are used for congestion management issue in IEEE-14, 30, 57 bus system. The comparative results between TCSC and SSSC are presented in this work. From obtained result, it is observed that SSSC yields superior results when compared to TCSC in phrase of real power loss and running cost.
