ENERGY EFFICIENCY DETERMINATION METHOD AND APPARATUS, AND POWER SUPPLY SYSTEM, ELECTRONIC DEVICE AND STORAGE MEDIUM

Provided in the present disclosure are an energy efficiency determination method and apparatus, and a power supply system, an electronic device and a storage medium. The method is applied to a power supply system, wherein the power supply system comprises at least two power supply devices. The method comprises: selecting a target device from at least two power supply devices, and determining an adjustment variable corresponding to the target device; determining a variable interval corresponding to the adjustment variable; setting a plurality of variable values within the variable interval as outputs of the target device in sequence, and when the output of the target device is set each time, determining the power supply efficiency of a power supply system according to the power value of each power supply device; and according to the plurality of variable values and a plurality of power supply efficiencies corresponding to the power supply system, searching for the maximum value of the power supply efficiency o
