The invention provides an energy efficiency control system and method for a hybrid power ship. The control system comprises a first diesel generator set, a second diesel generator set, a shore power supply, an alternating current bus, an energy storage unit, a direct current bus, a left motor, a left clutch, a left main engine, a right motor, a right clutch and a right main engine. The first diesel generating set and the second diesel generating set are connected with a shore power supply alternating-current bus; the alternating-current bus is connected to the direct-current bus; the energy storage unit is sequentially connected with the direct-current bus; the direct-current bus is connected with the left motor and the right motor; the left motor is connected with the left propeller and the left host; the right motor is connected with the right propeller and the right host. The unmanned aerial vehicle has the advantages that the propellers can be independently driven by a main engine,a motor or diesel-electric drive combining the main engine and the motor; the motor can work in a propelling state or a power generation state, and the reliability is high; the hybrid power ship energy efficiency optimal grey prediction control method is provided, and the problem that a diesel engine operates with the lowest oil consumption SFOC is fundamentally solved.
