The invention discloses a regional power distribution network reliability evaluation method and system considering vehicle-network interaction. The method comprises the steps of S1, data acquisition and processing; s2, simulating behavior data; s3, constructing a dynamic vehicle network interaction model; s4, calculating a reliability evaluation index of the power distribution network; s5, comprehensively evaluating the reliability of the power distribution network; according to the method, the influence of travel behaviors and charge and discharge characteristics of the electric vehicle on the power distribution network is comprehensively considered through a dynamic vehicle network interaction model, a random sample conforming to the operation characteristics of the power distribution network and the electric vehicle is generated through Monte Carlo simulation, and the randomness of travel, charge and discharge behaviors of the electric vehicle is comprehensively considered. The method can dynamically describe the double roles of the electric vehicle as the load and the energy storage resource through the dynamic vehicle network interaction model, effectively improves the reliability evaluation accuracy of the regional power distribution network, and can generate a random sample according with the operation characteristics of the power distribution network and the electric vehicle through Monte Carlo simulation. And the accuracy and robustness of evaluation are effectively improved.
