A new ship energy management algorithm to the smart electricity grid system

Abstract

Summary In this paper, a new energy management algorithm has been suggested for the ships connected with alternative energies considering the smart electricity grid features. The algorithm focuses on the use of optimum energy source on the shipboard based on the priorities of authorities such as the most economic, environmental, or both criteria at the ports. The algorithm is performed in MATLAB, and several case studies are simulated to validate the results. The 5 maritime nations, which are at different regions: United States, Belgium, Turkey, China, and Australia, are taken into account in the case studies. The actual data of a bulk carrier ship have been used to achieve tangible results in the simulations. The results of the case studies are compared to determine the changes of energy cost and released emission to meet demand of electricity on the ships. Capital cost of the proposed concept is also given to make an economic evaluation. The results show that the ship energy management algorithm provides the significant economic and environmental advantages. This paper aims to contribute to the importance of the ships in the smart electricity grid concept for the maritime and electricity sector representatives.

Comparison of External Costs of Diesel, LNG, and Electric Drive on a Ro-Ro Ferry Route

“…Furthermore, in 2019, the e-ferry Ellen started its operation between the Danish ports of Fynshav and Soby, with a power capacity of 4.3 MWh and being able to carry 30 vehicles and 200 passengers to distances up to 22 nautical miles between charges [52]. High investment costs of the infrastructure should be taken into consideration regarding the potential investments, which is also indicated by several authors [53][54][55].…”

“…Yiğit and Acarkan have described a novel algorithm of energy management for ships associated with the highlights of the smart grid. The algorithm centers around the utilization of an optimal energy source on ships, depending on the needs of the authorities.…”

Energy Management System in Naval Submarines

“…Moreover, AES has a significant feature of the integrated power systems (IPS), which utilize dc power distribution systems which require advanced control and management [38], [42], [43]. Furthermore, shipboard energy management algorithms start implementing renewable energy resources such as wind turbines and photovoltaics these days [44]. The snorkeling breaks acoustic and non-acoustic stealth of submarines by generating extremely huge noise and exposing the masts above the surface, but it is the most important activity for supplying energy to the systems at the same time.…”
