Beschreibung
Zusammenfassung:	Provided is a ship power system that comprises a first power storage device, a second power storage device, and a control system. The energy density of the first power storage device is larger than that of the second power storage device, and the output density of the second power storage device is larger than that of the first power storage device. When the intended use is power generation, the control system causes the first power storage device to discharge power with priority over the second power storage device so that a base power is continuously supplied to an onboard power load connected to an onboard busbar. When the intended use is system stabilization, the control system causes the second power storage device to charge/discharge power with priority over the first power storage device so as to compensate for frequency or voltage fluctuations of an onboard power system.
