Because of its comprehensibility, high flexibility, and quick programmability features, and dealing with fewer algorithm parameters, it has attracted significant research interests from numerous fields over a short time.


The Grey Wolf Optimizer (GWO) is a new optimization method applied to diversified objectives in different optimization tasks. Finally, the novelty of the paper is demonstrated by comparing with the existing publications in an extensively used two-area test system. A sensitivity study is also performed to examine the impact of the unpredictability in the parameters of the investigated system on system performance. It is also seen that SGWO based AFPID controller is highly efficacious in regulating the frequency compared to the standard PID controller. It is demonstrated that the SGWO method is superior to the GWO method in the optimal controller design task. The DPGS contains renewable generation such as photovoltaic, wind, and storage elements such as battery and flywheel, in addition to plug-in electric vehicles. Practical application in a Distributed Power Generation System (DPGS) with energy storage is then considered by designing an Adaptive Fuzzy PID (AFPID) controller using the suggested SGWO method for frequency control. The results are also contrasted to the Gravitational Search Algorithm, the Particle Swarm Optimization, and the Sine Cosine Algorithm and this shows the superiority of the proposed SGWO technique. The advantage of the presented SGWO over GWO is a better solution taking less execution time and is demonstrated by taking unimodal, multimodal, and fixed dimension test functions. The simplification in the original Grey Wolf Optimizer (GWO) method is introduced by ignoring the worst category wolves while giving priority to the better wolves during the search process. All of a pack's adults help to care for young pups by bringing them food and watching them while others hunt.A Simplified Grey Wolf Optimizer (SGWO) is suggested for resolving optimization tasks. Usually this male and female are the only animals of the pack to breed.

Wolfpacks are established according to a strict hierarchy, with a dominant male at the top and his mate not far behind. Wolves also eat smaller mammals, birds, fish, lizards, snakes, and fruit. A single animal can consume 20 pounds of meat at a sitting. When they are successful, wolves do not eat in moderation. These social animals cooperate on their preferred prey-large animals such as deer, elk, and moose. They are known to roam large distances, perhaps 12 miles in a single day. Wolves live and hunt in packs of around six to ten animals. Few gray wolves survive in Europe, though many live in Alaska, Canada, and Asia. In the lower 48 states, gray wolves were hunted to near extinction, though some populations survived and others have since been reintroduced. They do attack domestic animals, and countless wolves have been shot, trapped, and poisoned because of this tendency. Though they almost never attack humans, wolves are considered one of the animal world's most fearsome natural villains. But wolves and humans have a long adversarial history.

Adaptable gray wolves are by far the most common and were once found all over the Northern Hemisphere. Wolves are the largest members of the dog family. Much like barking domestic dogs, wolves may simply begin howling because a nearby wolf has already begun. A lone wolf howls to attract the attention of his pack, while communal howls may send territorial messages from one pack to another. Wolves are legendary because of their spine-tingling howl, which they use to communicate. Current Population Trend: Stable What are gray wolves?
