The controller 110 transmits a charge signal or a discharge signal to the ESS 120 and determines an object to which the charge power of the ESS 120 is supplied. A detailed description of the controller 110 will be given later.

The ESS 120 is charged with electric power generated by the generator 140, discharges the charged electric power, and supplies the electric power to the required electric power. This will be described in detail with reference to FIG. 2 to FIG.

2, which illustrates an AC grid, ESS 120 may include a battery 121 and a converter 122 coupled to battery 121 and generator 140.

At this time, the converter 122 converts the produced electric power produced by the generator 140 into DC power and supplies the DC power to the battery 121, converts the charged electric power charged in the battery 121 into AC power, ).

In some embodiments of the present invention, the generator 140 may be a fossil fuel generator such as a fuel cell generator, an LNG generator, and a diesel generator that meet the pollutant emission regulations, as well as an environmentally friendly energy generator such as a wind turbine, a wave generator, . At this time, a plurality of generators 140 may be connected in parallel to generate electric power for supplying to the electric power facility 150, but the present invention is not limited thereto and can be variously changed.

Here, the power facility 150 may include all in-ship loads 152 used in the ship as well as propulsion means 151 such as a thruster or propeller for propelling or redirecting the ship .

Specifically, the AC power generated in the generator 140 is converted to DC power in the AC / DC converter 122 and stored in the battery 121. The DC power stored in the battery 121 is supplied to the DC / AC converter 122, And may be provided to the power facility 150 that is converted to AC power and driven by AC power.

Referring to FIG. 3, which illustrates a DC grid, the ESS 120 may include only a battery 121.

Specifically, the AC power generated in the generator 140 is converted to DC power in the AC / DC converter connected to the generator 140 and provided to the DC grid, and the converted DC power is supplied to the battery 121 connected on the DC grid Lt; / RTI >

In addition, the DC power stored in the battery 121 is provided directly on the DC grid and can be provided to the propulsion means 151 driven by AC power through the in-vessel load 152 driven by DC power or the DC / AC converter have.

Specifically, the PMS 130 can provide a signal for increasing the operation rate of the generator 140 at the first time point and lowering the operation rate of the generator 140 at the second time point different from the first time point.

Accordingly, the generator 140 increases the amount of power supplied to the ESS 120 at the first time according to the signal provided from the PMS 130, and supplies the power to the ESS 120 at the second time The amount of power can be reduced.
