The invention discloses an energy management method for a multi-stack fuel cell hybrid power generation system, and the method comprises the steps: taking a load power demand and a storage battery charge state as input state variables, taking the minimum equivalent value loss in a system operation process as a target, and adjusting the output power of each unit in a fuel cell multi-stack system, the management battery pack supplements system vacancy power or absorbs braking power. The output voltage and current conditions of each unit and the storage battery pack of the fuel cell multi-stack power generation system are detected in real time, the output power of each unit is distributed according to the demand of load power, the equivalent value loss in the system operation process is minimum, and the system reliability is improved. Therefore, the economical efficiency of the system can be maximized under the condition that the load power requirement is met, the service life of the fuel cell and the service life of the storage battery are prolonged, the SOC of the storage battery pack can be maintained within a certain range, and stable and long-term operation of the system is guaranteed.
