Abstract

POWER SYSTEM OF SHIP A power system of a ship includes a first power storage device , a second power storage device , and a control system . The first power storage device has an energy density higher than that of the second power storage device . The second power storage device has a power density higher than that of the first power storage device . The control system is configured to: as a power generator application , prioritize discharging the first power storage device over discharging the se cond power storage device , such that base power is continuously supplied to an onboard electrical load connected to an onboard bus ; and as a grid stabilization application , prioritize charging/discharging the second power storage device over charging/disch arging the first power storage device to compensate for frequency variation or voltage variation of an onboard power grid .
