The present invention provides an electric power system of a ship. The electric power system of a ship comprises: a first power unit having a first power grid; and a second power unit having a second power grid, which is different from the first power grid, wherein the first power unit may include: a first load device which is electrically connected to the serial power grid; a propulsion module which generates propulsion force to move the ship, wherein the propulsion module includes a propulsion member, a main engine, and a propulsion shaft transferring the power of the main engine to the propulsion member; and an axial generator which produces power based on the rotation of the propulsion shaft, and the second power unit may include: a second load device which is electrically connected to the AC power grid, and consumes less power per unit time than the first load device; and a generation engine which transfers power to the second load device. The electric power system of the ship can improve fuel consumption efficiency.
