Load frequency control analysis using AGC, TCPS and SMES

Frequency deviations and inter-area tie-power fluctuations from their respective scheduled values following a local load disturbance which is a source of great concern in interconnected power system operation and control. In this paper, two methods are proposed to minimize such deviations and thereby enhancing the performance of Automatic Generation Control (AGC) of an interconnected power system which includes Thyristor Controlled Phase Shifter (TCPS) & Superconducting Magnetic Energy Storage system (SMES) with Fuzzy Gain Scheduled (FGS) including supplementary controller for the improvement of Load Frequency Control (LFC). The simulation results show that the SMES performs more effective primary frequency control compared to TCPS. This paper provides strong theoretical support for the implementation of TCPS & SMES in the real-world LFC problem solutions.
