Application of Grey Wolf Optimization based Multi Agent System for All Electric Naval Ship

Abstract

The concept of an all-electric naval ship, while delivering unequalled advantages in terms of efficiency and operational flexibility, has raised new concerns about stability and power flow regulation. The introduction of a full power electronics power system has resulted in additional system dynamics challenges, especially when dealing with the new medium-voltage direct current distribution. Researchers have considered two main approaches to ensuring the power system's secure operation: reducing the dynamics of the large load to operate in a range of dynamics compatible with traditional generation systems, or making the generator set smarter via its power electronics interface. Power availability is crucial in the shipping industry, which depends on regular power output and the reliability of power and propulsion systems. This study proposes a multi-level technique for hybrid power generation control. To do this, a mathematical model for each power system component is provided first, followed by a model of the entire on-board power system. The results demonstrated that the proposed approach successfully improves the stability of an interconnected power system when compared to GA-based MAS.
