Intelligent management of integrated energy systems in remote maritime environments utilizing fuzzy modes

This paper explores isolated maritime environments equipped with an integrated energy system (IET) to fulfil the energy requirements of nearby communities. These environments are presumed to lack grid access but possess a connection point for a floating energy source capable of supplying consistent electricity for a limited duration. The study introduces a novel management system for the efficient operation of IES in such environments, utilizing an innovative multi-mode approach. Specifically, the system includes several management modes, each employing a distinct management strategy for the IET. These modes are implemented using fuzzy logic tools, with a core of IF/THEN control rules that enable flexible and rapid decision-making. The fundamental concept is that the use of modes in decision-making inherently prioritizes specific operational objectives and consumption needs based on current conditions. The proposed system comprises three modes and is tested through a series of simulated scenarios. Results indicate that the IET can provide flexible energy management that adapts to dynamic conditions, outperforming a single-strategy system.
