The invention discloses a graph theory-based load shedding distribution method for a power distribution network containing distributed power generation, and the method comprises the steps: combining a graph theory-based method with the related constraints of a power system, and taking the purposes of preferentially guaranteeing the power supply of important loads and guaranteeing the power supply of as many loads as possible as possible; calculating to obtain load shedding distribution schemes of the power distribution network under different load shedding instructions of the main network; when the main network issues a load shedding instruction, matching is carried out according to a last calculation result; according to the method disclosed by the invention, accurate load shedding operation can be carried out under different load shedding instructions of a main network according to related calculation principles of a graph theory by needing measurement information such as output, control parameters, an actu
