According to the variable-speed pumped storage power station output obtaining method for LC economic evaluation, typical operation scenes of a variable-speed pumped storage power station are constructed firstly, then the output of the variable-speed pumped storage power station is obtained based on specific variable-speed pumped storage operation strategies for the typical operation scenes, and the variable-speed pumped storage operation strategies comprise the steps that the output of the variable-speed pumped storage power station is obtained based on price deviation, storage capacity deviation and time deviation; judging the working condition of the variable-speed pumped storage power station in the next power transaction time period, determining the output of the variable-speed pumped storage power station in the next power transaction time period based on the working condition and the load difference, and updating the storage capacity of the variable-speed pumped storage power station based on the storag
