Congestion Management by TCPST In IEEE 9 Bus System Using Matlab Simulink
نویسندگان
چکیده
Increased electric power consumption causes transmission lines to be driven close to or even beyond their transfer capacities resulting in overloaded lines and congestions. Flexible AC Transmission Systems (FACTS) provide an opportunity to resolve congestions by controlling power flows and voltages. Main focus in this paper lies on the Thyristor Controlled Phase Shift Transformer (TCPST). IEEE 9 bus system is considered for congestion management. Parameters for bus system are predefined by IEEE. Voltage and current is measured individually at each bus and in transmission line between any two congested bus, TCPST is installed. The opening and closing time of Thyristors in TCPST are controlled by PID controller. All this system is implemented and analyzed in MATLAB Simulink.

Abstract: The deregulated power system is quite popular in now a days. The increased power demand has forced the power system to operate very closer to its stability limits. So transmission congestion and voltage instability problems are arise in the power system. Due to the congestion in the network, not always possible to transmit the all contracted power. Congestion management is a tough tas...

ABSTRACT Bus communication system was established mainly using Sim Events module in the software of Matlab/Simulink. Performance indexes of bus system, which embraces worst-case response time of messages and bus load, were separately gained by theoretical calculation, experiments in Matlab and CANoe. The calculation and experiment results were compared sufficiently, and it concludes that bus sy...
