Background: A hybrid energy storage system (HESS) is an energy storage system with different types of energy storage devices such as batteries, capacitor banks or flywheels. A hybrid power system using the HESS can enhance the vessel performance, safety and integrity by operating the power system at optimal conditions. This is enabled by energy storage devices that allow the power imbalance between the power sources and consumers. However, the degree of benefits from the hybrid operation heavily depends on the dynamic load profile of the power plant in real operation. In the current practice, such a profile is not available or not relevant for the new design. Furthermore, the operational profile should also adapt to the capability of the new design, which is not accounted by the designers.

Objective: In this project, the existing operational load profile in a long horizon, typically years, will be used to create a relevant load profile that can be used in the design evaluation of the HESS. Data analysis methods for identification of the worst scenario and synthesizing representative time series will be developed and applied to the given data. The produced dynamic time series will be used for finding the optimal HESS solution for the vessel.
