Power Flow Regulation of a Multi Area System with Fuzzy Gain Scheduled PI (FGPI) Controller for Static Synchronous Series Compensator (SSSC) with Superconducting Magnetic Energy Storage System (SMES)

In this study, a fuzzy gain scheduled proportional and integral (FGPI) controller was developed to regulate the power flow regulation of Static Synchronous Series Compensator (SSSC) in a multi-area power system. Also, this FGPI was developed for the SSSC without and with Superconducting Magnetic Energy Storage (SMES) system. Two performance criteria were utulized for the comparison. First, settling times and overshoots of the real and reactive power flow were compared. Later, the THD of the Voltage Source Inverter (VSI) output voltage were compared. All the models were simulated by Matlab 7.0-Simulink software. The simulation results show that the FGPI controller developed in this study performs better for the SSSC system with SMES than the other without SMES.
