Each vessel has a different load profile based on its application. Among the vessels, the ones that have electrical propulsion systems with high fluctuations of propulsion demand power incur poor fuel consumption efficiencies due to: a) low loading of the generators and the lower efficiency in lower loads, and b) variations in the output power of the generators. Therefore, it may be economically feasible to install energy storage units in such ships to improve generator efficiencies.Given the load profile of a vessel, this paper formulates a simple but general deterministic dynamic optimization problem to find the optimal loading strategy for the ship generators in the presence of an energy storage unit. It then adds an outer layer to the optimization problem that finds the optimum capacity for the energy storage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
