The invention relates to a current voltage plan generation method for a multi-end flexible direct current isolated island power grid transmit end, belonging to the technical field of voltage control of a power system. First, a multi-end flexible direct current transmit end isolated island network is simplified reasonably, and a corresponding network model equation is established; then an isolated island power grid real-time voltage control optimization model is built; and approximate calculation is performed on flexible direct reactive power according to an active power prediction range of each wind farm. A two-stage robustness optimization model is established according to the first three steps, and finally, iterative solution is performed according to a column constraint generation algorithm so as to obtain a generated flexible direct current voltage plan. The method fully considers uncertainty of wind power and coordination of real-time voltage control devices. A multi-end flexible direct current isolated island power grid transmit end station uses the voltage plan generated by the method, so that the real-time voltage control effect of the isolated island power grid is enhanced, system voltage fluctuation is reduced, and stored system dynamic reactive power is increased.
