Abstract: A method of controlling power transfer in a power system including a main bus, having a first and second bus sections, the first bus section connectable to the second bus section, first and second power generating units connectable to the first and second bus sections, a first and second drive systems connectable to the first and second bus sections, a central energy storage system, and a control system. The first and second drive systems include first and second bi-directional power converters connectable to the central energy storage system, and wherein the control system is arranged to control the first bi-directional power converter to transfer power from the first drive system to the central energy storage system, and to control the second bi-directional power converter to transfer power from the central energy storage system to the second drive system.

Abstract: There is provided mechanisms for controlling movement of a propeller shaft on a vessel. A controller includes processing circuitry. The processing circuitry is configured to cause the controller to detect movement of the propeller shaft by determining a signature of a sustained oscillation of the propeller shaft. The processing circuitry is configured to cause the controller to control movement of the propeller shaft according to the determined signature.
