Inserting of heuristic techniques into the stability regions for multiarea load frequency control systems with time delays

The design and optimization of robust controller parameters are required to improve the performances keep stability load frequency control (LFC) system. In addition, reducing number iterations computational time is very important for swiftly tuning system reach rapidly. For this purpose, study presents inserting heuristic techniques into regions method identified in proportional-integral (PI) controllers space multiarea LFC systems with communication delays (CTDs). This consists two steps: determination region application heuristics. Stability found via boundary locus (SBL) moth-flame (MFO), particle swarm (PSO), sine cosine algorithm (SCA), slime mould (SMA) whale (WOA) inserted applied region. a cost function having domain specifications developed improving it compared well-known integral error functions. Also, region, which tolerates any parameter delay variation, significance given robustness analysis. It observed from analyses that better outputs have been obtained function. Steady state errors minimized transient improved proposed method. Moreover, desired achieved lower iteration (approximately more than about 89% reduced according classical approach) without deteriorating stable structure by
