The invention discloses a pumped storage-wind power joint scheduling method of considering wind power output uncertainty. The method comprises the following steps: formulating a pumped storage-wind power joint operation plan aiming at a power generation system comprising a pumped storage power station, conventional power units and a wind power plant; building a target function based on fuel cost and start/stop cost of the conventional power units and determining constraint conditions; generating all possible output sets of the conventional power units as search spaces; generating decision variables with randomly distributed positions in the search spaces; and with the decision variables as countries, determining a result by an empire competition algorithm to control the output of the conventional power units of the power generation system. A spinning reserve risk constraint is introduced aiming at the wind power output uncertainty; the effect of the wind power output uncertainty is finely considered; overall coordination of the operating economy and reliability of the power generation system comprising wind power can be achieved; and the economic benefits of the system can be significantly improved through joint operation of the pumped storage power station and the wind power plant by regarding the pumped storage power station as the technical means of stabilizing the wind power output volatility.
