Electric power system for supplying electric energy to a vessel

An electric power system for supplying one or more direct voltages from shore-side to a vessel, the electric power system comprising:

• one or more controllable converters configured to receive the electric power from a shore-side alternating voltage network and to produce the one or more direct voltages;
• at least one transformer configured to connect the one or more controllable converters to the shore-side alternating voltage network, the at least one transformer comprising a primary winding for being connected to the shore-side alternating voltage network, and a plurality of secondary windings each being connected to a corresponding one of the controllable converters,
• electric connectors configured to connect an electric circuitry of the vessel;
• one or more direct voltage links configured to transfer the one or more direct voltages from the one or more controllable converters to the electric connectors;
• and
• a control system configured to receive a control signal from the vessel and to directly control the one or more controllable converters in accordance with the received control signal to control the one or more direct voltages to be transferred from the electric connectors to the electric circuitry of the vessel.
