Can a marine vessel power system be considered as a microgrid?

Hence, a marine vessel power system with photovoltaic, WT, SWE, and ESS can be considered as a specific mobile islanded microgrid. Consequently, the main target of this paper is to design a new optimal fractional order fuzzy PD+I load frequency controller (LFC) for islanded microgrids in a ship power system.

What is a shipboard microgrid?

They include propulsion loads, ship service loads, and pulsed loads. The PMS/EMS acts as a coordinator between the ship loads and power sources. A shipboard microgrid also includes electronic converters, transmission networks, communication lines, and other auxiliary components that enable the integration and operation of different energy sources.

Do shipboard microgrids integrate energy storage systems?

This paper presents a comprehensive review of such strategies and methods recently presented in the literature associated with energy management in shipboard microgrids integrating energy storage systems and examine the different techniques that can be utilized to achieve optimal system performance.

What is EMS for shipboard microgrids?

In the context of EMS for shipboard microgrids, the available literature focuses mainly on achieving optimal power plant design, optimal sizing and management of battery energy storage systems, and optimal scheduling of power and energy.

What is a ship microgrid (SMG)?

A SMG is essentially a mobile microgrid that operates in two modes i.e. islanded and grid-connected, depending on whether the ship is at sea or at a seaport. The architecture of ship microgrids shares similarities with terrestrial microgrids, such as the use of renewable energy sources and the massive use of electronic converters.

Are pulse loads a problem in a shipboard microgrid?

While the use of alternative power sources such as fuel cells and RESs can improve fuel efficiency, the presence of pulse loads such as radars and sonars is challenging. These pulse loads can exceed the ship’s rated generation capacity, leading to unstable operation of the electrical shipboard microgrid.
