A Refined Load Distribution Method for Large Hydropower Stations With Multiple Units Considering Constraints of Substations

Large hydropower stations often undertake peak regulation tasks during the non-abandoning water season. This requires a reasonable arrangement of unit commitment and load distribution (UCLD). In this study, a load distribution model considering constraints of substations was established, and a novel...
