Robust Stabilizing Controllers to Automatic Generation Control for Load Frequency Control Application

Since superconducting magnetic energy storage (SMES) unit with a self-commutated converter is capable of controlling both the active and reactive powers simultaneously and quickly, increasing attention has been focused recently on power system stabilization by SMES control. This study presents the effects of novel control strategies o f self-tuned fuzzy proportional integral (FPI) c ontroller and fuzzy frequency (F F ) controller associated with the automatic generation control (AGC) including SMES unit . The effects of the self-tuning configuration with FPI controller in AGC is also compared with that of FF controlled AGC on SMES control . The simulation results show that both self tuning control scheme s of AGC are very effective in damping out of the oscillations caused by load disturbances and it is also seen that the F F controlled AGC with SMES perform better primary frequency control compared to F PI controll ed AGC with SMES.
