The invention, which belongs to the field of the electric power technology, relates to an alternating-current/direct-current distribution network planning method with consideration of new energy access. The method comprises the following steps: S1, according to a VSC circuit model, constructing a VSC power flow calculation model; S2, expressing an alternating-current/direct-current hybrid system topological structure by using a binary variable and two binary matrixes; S3, establishing a first layer of optimization model; S4, for randomness of a load, wind power generation, and photovoltaic power generation, simulating a plurality of scenes by using a monte carlo method; S5, for various scenes, establishing a second layer of optimal power flow model to obtain outputs of the rest of generators of the hybrid system; and S6, substituting mean values of generators and load of the plurality of scenes into the first layer of optimization model to carry out optimal hybrid system topological structure solution. Because of convenient embedding into the existing genetic algorithm, the result precision is improved and the corresponding algorithm basis is provided for alternating-current/direct-current distribution network planning.
