The invention relates to a method for determining the best points of a parallel power supply system based on the golden section of efficiency and current sharing performance. On the basis of respectively obtaining the expression S=ψ(i) between standard deviation S and power module load current I and the expression η-φ (I) between efficiency η and power module load current I corresponding to the best points I1 and I2, the invention applies the golden section principle in geometry to obtain the comprehensive optimal load current I for power module operation. The value represents the optimal comprehensive performance index of efficiency and current-sharing response concentration in the current-sharing process of the parallel power supply system and its corresponding online module load current value, which provides a basis for the optimization control of efficiency and current-sharing of the parallel power supply system. It can effectively determine the optimal corresponding working point of the efficiency and current sharing comprehensive index of the parallel power supply system, and provide reliable guarantee for the safe, efficient and reliable operation of the parallel power supply system.
