Abstract

The dynamic stability of the realistic two-area multi-source (TAMS) power system is appraised under the control of various fractional order controllers (FOC) in present work. Initially, the area-1 of TAMS is subjugated with 10% step load disturbance (SLD), and its dynamic variations are comparatively analyzed under the performances of FOPI, FOPID, and tilt-integral-derivative-filter (TIDF) controllers individually. Moreover, the controllers are individually optimized with the fruit fly algorithm (FFA), and the simulation results demonstrated that the TAMS power system stability is effectively controlled with the TIDF controller. Taken the communication time delays (CTDs) with TAMS to bring the investigative analysis near to the real-time environment, and its significant impact on the system stability is showcased. Further, the two areas are integrated with the battery energy storage (BES), and the Thyristor-controlled phase shifter (TCPS) is placed with the tie-line to enforce them as the territory control approach. Simulation analysis revealed an enhancement in TAMS system behavior with the deployment of the BES-TCPS strategy.
