BES and SSSC Based Supplementary Control for Frequency Regulation of Multi Area Interconnected Power System Network

This paper develops the tilt-integral-derivative (TID) plus filter (F) based on the fruit fly optimization (FFO) algorithm for the stability of the interconnected power system (IPS). The dynamic behavior of considered IPS is analyzed by laying the step load disturbance (SLD) of 10% in area-1 under the FFO-based TIDF controller. However, the efficacy of TIDF is revealed with other available controller performances in the literature. Moreover, the time delays (TDs) are believed with the IPS network to conduct the dynamic analysis near to practicality, and their significance on the system performance is revealed. Further, the system is integrated with the supplementary control mechanism of battery energy storage (BES) and static synchronous series compensator (SSSC) for performance enhancement. Simulation results reveal the improvement in system dynamic behavior with the implementation of the BES-SSSC strategy as a supplementary controller.
