The invention belongs to the water power scheduling operation field, and relates to a super-large scale hydropower station group short period practical scheduling method; the method divides all hydropower stations into three types according to scheduling characteristics including system hierarchy, space attributes, task requirements and plan particularity, and proposes an abandoned water correction strategy based on pitch peak response and a valley period load balancing reduction strategy, thus realizing checking analysis and output adjustment of power stations of a fixed scheduling mode; forcascade hydropower stations of middle and small rivers, the method takes the total output process as control conditions, uses the minimum total power consumption as an object, thus optimizing load distribution among the cascade hydropower stations; for large scale river cascade hydropower stations, the method builds a pitch peak scheduling model, proposes a balance power station equal load factorscheduling method, thus realizing system pitch peak response and all time load balance. The method can fast provide a reasonable water power scheduling result, thus satisfying power grid real operation timeliness and practicality requirements, and providing a new technical path for effectively solving super-large scale hydropower system scheduling problems.
