The invention discloses a bearing capacity evaluation method, system and equipment for a distributed power supply and a medium, and the method comprises the steps: constructing a distributed power supply bearing capacity evaluation model containing a bearing capacity evaluation model based on voltage fluctuation based on the actual condition of the distributed power supply in a power distribution network; and obtaining the access capacity of the three indexes at the control critical point by solving a calculation formula based on the voltage loss, the line current carrying and the voltage fluctuation through back-stepping, and obtaining the maximum capacity which can be borne by the distributed power supply connected to the distribution network. According to the method, the requirement of a power grid for the operation control value of the distributed power supply is referred, on the basis of the two operation indexes of voltage loss and line current carrying, the operation index of voltage fluctuation is add
