In Task 2.3 of the FLEXSHIP project, we develop and investigate the energy management system for the vessels. The main objective is to enable an efficient and resilient operation of the energy supply system with significantly reduced emissions.
For the development of the energy management, a layered, modular, and scalable high-level digital twin will be prepared. The digital twin includes simulation models for all relevant components like the battery energy storage system, power converters, combustion engine (in the case of hybrid vessels), and the power consumption by the powertrain and auxiliary loads. It enables the testing and comparison of different approaches for the energy management. This includes the evaluation of optimisation methods to find the best operation point for each timestep.
The claim here is that the applicability of the energy management should not be limited to the demonstrators in the FLEXSHIP project but can also be flexibly transferred to other types of ships. This will be realized by parametrizable models and algorithms.
There are strong connections between the tasks in the WP2, that are regarded: The electrical architecture (task 2.1) influences the energy management system due to the structure of the energy supply system of the vessels. The digital twin will be developed in close cooperation with task 2.5.
