Ameliorating the Performance of LFC in Dual Area Hydro Thermal Power System with AC/DC Lines

Abstract

In this paper, fuzzy PID optimized using the seagull optimization algorithm (SOA) is introduced for load frequency control analysis. For investigation, the considered model of dual area hydro-thermal system (DAHT) is targeted with a 10% SLP on area-1. Moreover, non-linear practicality constraints such as (GDB) governor dead band and (GRC) generation rate constraint are believed with the DAHT. However, the sovereignty of fuzzy PID is revealed with those of PI/PID. Later, to ameliorate the performance of the DAHT system an HVDC line is enacted with the AC existing line in parallel. Simulation results showcased the improvement in DAHT performance with AC/DC line. Further, the DAHT system is impressed with random step loadings to reveal the rigidness of the suggested regulatory mechanism.
