The invention relates to a charging station and power distribution network collaborative planning method and device considering V2G energy storage and line margin, and a medium, and the method comprises the steps: building a charging station multi-target planning model based on the load spatial-temporal distribution of an electric vehicle with the minimum comprehensive cost of the charging station and the maximum V2G energy storage equivalent capacity as optimization targets, and carrying out the locating and sizing of the charging station; a coupling relation between a traffic network and a power distribution network and a power distribution network line margin are comprehensively considered, minimization of the line margin and the comprehensive cost are taken as optimization targets, a power distribution network multi-target expansion planning model is constructed, and expansion planning is carried out on the power distribution network; and carrying out cooperative solution on the charging station multi-target planning model and the power distribution network multi-target expansion planning model by adopting a normalized normal constraint method to obtain a final charging station locating and sizing result and a power distribution network construction scheme. Compared with the prior art, the economical efficiency and flexibility of system operation are improved, new energy consumption is promoted, and safe, economical and stable operation of the power distribution network can be guaranteed.
