Hvorfor installere batterier på skip? (Mange produserer jo uansett all strøm fra egne dieselgeneratorer.)
Stort potensial for batterier til sjøs
Optimized use of Energy Charged from Shore in Plug-in Hybrid Marine Vessels
Optimal Sizing of Battery Energy Storage Systems for Hybrid Marine Power Systems
This paper introduces an analytical design methodology for Battery Energy Storage Systems (BESS) in hybrid marine vessels. Models for performance evaluation of a BESS composed by a battery array, an AC/DC power converter and a transformer are introduced and used to evaluate the potential fuel saving...
Including Power Management Strategies and Load Profiles in the Mathematical Optimization of Energy Storage Sizing for Fuel Consumption Reduction in Maritime Vessels
Choosing the optimal type and size of energy storage for a given hybrid maritime vessels is challenging. Investment cost, fuel saving and energy storage expected life time will be affected by the choices. Furthermore, the optimum choices depend on the operation profile of the vessel as well as safet...
Model Predictive Control of Marine Power Plants with Gas Engines and Battery
The electric load demand on marine vessels is constantly changing during some operational modes, such as in harsh weather or complex operations. Therefore, diesel engines are typically used to handle these variations. Gas engines reduce the CO2 due to a lower carbon content in LNG compared with dies...
Design of Minimum Fuel Consumption Energy Management Strategy for Hybrid Marine Vessels with Multiple Diesel Engine Generators and Energy Storage
The paper presents an analytical method for estimation of the fuel saving potential resulting from installation of energy storage on-board of marine vessels equipped with multiple diesel engine generators. The method is based on quasi-steady-state assumptions and does not require precise a-priori kn...
