Performance Improvement in Multi Area Diverse Source Interconnected Power System under IDDN Controller with AC-DC Line

This paper presents the soft computing algorithm-based modified classical controller for the load frequency control (LFC) of a multi-area diverse source (MADS) system. The modified classical controller of the integral-double derivative with filter (IDDN) optimized with the donkey and smuggler technique (DST) is presented for the interconnected power system (IPS) network’s frequency regulation. However, the efficacy of the suggested DST-based IDDN is validated with the other regulator's performance. To bring the study closer to reality, the MADS is addressed with communication time delays (CTDs) and its performance is evaluated using a 10% step load (SLD) disruption in area-1. Further, the high-voltage DC line is incorporated with the MADS system and the investigation reported the improvement in the performance. Finally, the suggested DST-tuned IDDN in coordination with the AC-DC lines of territorial control strategy robustness is verified through the sensitivity analysis.
