The invention discloses a multi-variable-speed pumped storage power station system cooperative operation control method, which comprises the following steps of: determining an expected working condition combination of a next power transaction time period based on a target storage capacity value of each variable-speed pumped storage power station in a system, and calculating an adjustment upper limit of the system according to the expected working condition combination; and judging whether the load difference of the power system in the next power transaction period is smaller than the adjustment upper limit of the system or not, if so, taking the expected working condition combination as the optimal working condition combination, otherwise, correcting the expected working condition combination based on the adjustment range constraint of the system, and taking the corrected expected working condition combination as the optimal working condition combination. And inputting the optimal working condition combinatio
