Offshore Powering with a Closed Loop and Bus: Coupling Energy Storage for Maritime Electrical Networks

The current usage of the term hybrid electric power, when referring to electrical networks installed on offshore and marine assets, describes the coupling of energy-transformation systems (ETSs) that utilize different technologies to exchange energy with the electrical network. An ETS is composed of an energy-transformation device (ETD) and, if necessary, an energy converter that is used to match the electrical characteristics of the ETD to those of the electrical network; the converter facilitates the exchange of energy between the ETD and the electrical network at the required rate. An ETS may also be considered a source if it is able to supply net positive energy to the electrical network for consumption by the loads.
