The invention discloses a joint optimization scheduling method and system for multiple cascade power stations, and the method comprises the steps: determining a corresponding station-level drainage basin region for any cascade power station in combination with the position information of each cascade power station; according to the upstream and downstream relation and the corresponding station-level drainage basin areas, the incoming water prediction amount of any cascade power station in the short-term period is determined in sequence; according to the current water level data of any cascade power station and the corresponding incoming water predicted amount, determining a predicted water head of any cascade power station in a short-term period; establishing a short-term generating capacity maximum model according to the predicted water head of each cascade power station; and on the basis of the established short-term generating capacity maximum model, solving the optimized output of each cascade power stati
