The invention discloses a distributed photovoltaic voltage out-of-limit edge control method, a distributed photovoltaic voltage out-of-limit edge control device and a medium. The method comprises the following steps: continuously monitoring distributed photovoltaic state parameters through a distributed power supply access unit on a preset edge side; according to the regulation and control parameters received by the distributed power supply access unit and the state parameters of the distributed photovoltaic system, whether the distributed photovoltaic system has voltage out-of-limit is judged, and the state parameters comprise the property right demarcation point voltage and the duration of the property right demarcation point voltage; and under the condition that the voltage of the distributed photovoltaic system is out of limit, according to the out-of-limit degree of the distributed photovoltaic system, the distributed power supply access unit is utilized to control the running state of the distributed ph
