Effect of TCSC with Communication Delay Latencies on LQR- Fuzzified LFC-DR Model

From various researchers, the implementation of Demand Response to Load frequency control(LFC-DR) had gained importance. Good dynamic performance is obtained for LFC-DR from past studies when tuned with conventional Controllers. An attempt was made to analyze the effect of communication delay latency with Series Compensator for the load frequency with Demand Response (LFC-DR) model. Here the Thyristor Controlled Series Compensator (TCSC) is used, thus forming TCSC-LFC-DR model. A real time simulation was done by TCSC, from which the output and input values are obtained. The application of using TCSC in the system is modeled by System Identification Tool box. Rational approximations are used for power system dynamics linearization with 5th order. The gains of the PID controller are Fuzzified using intelligent controllers for the better understanding of the dynamic performance of LFC-DR model. Stability of the system is guaranteed on varying the parameters of the system at various loading conditions.
