With the completion of task 2.3 “Energy management system development and optimization”, a modular and adaptable energy management system (EMS) has been developed, which will be integrated into the demonstrator vessels DEMO-1 Gunnerus and DEMO-2 Atatürk in the further course of the project.
As a basis for EMS design and investigation, a simulation environment was established. This includes a generalized and extensible component model library. In addition to a base class containing the basic functionalities for all components, the following models were developed: External data class (propulsion load, hotel load), converter class (gensets), energy storage class (fuel tank, battery energy storage), and energy import class (charging stations). The simulation framework connects the on-board power system with the EMS strategies.
The implementation of the EMS strategies includes both rule-based approaches, such as mathematical equations and deterministic finite state machines (FSM), and optimisation-based approaches, including mixed-integer linear programming (MILP) and equivalent consumption minimization strategy (ECMS). These strategies have been tested on various load profiles (synthetic data and DEMO vessel measurements), evaluating the reduction in fuel consumption and emissions. Simulation results show promising outcomes.
For further project progress, an implementation plan has been mapped out, which includes guidelines for implementation (control levels, safety margins, interface tables, proposed communication sequence) as well as ideas for future expansions (e.g., integration of PV, and fuel cells).
The outcomes of T2.3 are reported in the deliverable D2.3, which will be publicly available soon.
