The Line flow limit is one of the major challenges faced by electric utilities. The prevailing load conditions cause congestion in transmission line. A decisive control action is essential to relieve the congestion by allowing the power to flow in a different route in the same system. The rerouting of power is possible by controlling the generation at a bus or controlling the load in such a way that the power is rerouted through the other lines present in the power system. In this paper, an attempt has been made to relieve the congestion using a sensitivity based direct method and Genetic algorithm (GA) based optimization technique, wherein the power flows in the transmission lines are maintained within the security limits by using both generation shifting and load control. GA is used to calculate the amount of generation and load control required for congestion management in the system. The results of the sensitivity based direct method for congestion management are compared with the results of GA based congestion management technique by implementing both the proposed methods on IEEE 5 bus system and IEEE 30 bus systemwith a congested line. The effectiveness of each algorithm is also analyzed by applying the techniques on hardware of reduced order model of IEEE 5 bus system. It is found that GA based method is able to alleviate the overloads in transmission line more effectively than the direct method

The concept of Flexible AC Transmission System (FACTS) is made possible by the application of high power electronic devices for power flow control in transmission line. Thyristor Controlled Series Compensator (TCSC) controls the power flow in transmission lines by varying the impedance of TCSC by controlling the delay angle of thyristors. This paper presents a conceptual study on the working of TCSC to observe the variation in transmission line reactance with change in the triggering angle of the thyristors using Simulink in MATLAB. The control circuit for each thyristor is designed in MATLAB to generate the requisite gate pulses. The TCSC module is designed for operation in capacitive mode and the variation in net reactance by changing the triggering angle (α) is determined and tabulated. The region of operation is from 130° to 180° where the reactance of the TCSC was observed to be reducing with increase in α. © Research India Publications.
