The invention discloses a building method for the maximum penetration capacity model of a random power supply. Maximum penetration capacity of the random power supply in a power distribution network is used as a target function, and the maximum penetration capacity model of the random power supply is built by considering a voltage deviation constraint condition. The invention also discloses a solution method for the maximum penetration capacity model of the random power supply. The model is solved by employing a genetic optimization method. A plurality of random power supplies can be simultaneously analyzed, the maximum penetration capacity of the plurality of random power supplies which are simultaneously connected to the grid can be determined, the model is high in solution optimizationcapability and rapid in calculation speed, and real-time calculation of dynamic penetration capacity of a plug-and-play random power supply can be met; and the model provides a reference basis for determination of real-time d
