The invention discloses a control method and system of a marine hybrid power system. The control method comprises the following steps: receiving an operation instruction sent by a user; the operation instructions comprise all lithium battery pack grid connection starting instructions, all lithium battery pack charging starting instructions and all lithium battery pack splitting instructions; executing a control method for starting grid-connected discharge of the lithium battery pack according to all the lithium battery pack grid-connected starting instructions; executing a control method for starting charging of the lithium battery pack according to all the lithium battery pack starting charging instructions; and executing the control method for splitting the lithium battery pack according to the command for splitting all the lithium battery packs. According to the technical scheme of the embodiment of the invention, starting, grid connection, charging, discharging and shutdown splitting of the multiple lithium battery packs are controlled according to the operation instruction sent by the user; therefore, the functions that the multiple lithium battery packs of the hybrid power ship start grid connection and discharge to the alternating-current power grid, the alternating-current power grid charges the multiple lithium battery packs, and the multiple lithium battery packs stop and are disconnected are achieved.
