The invention relates to the technical field of power systems, and discloses a
power optimization scheduling variable reduction method and
system based on data driving, and the method comprises the steps: enabling a plurality of physical units to be integrated into a virtual unit, recording and analyzing the unit parameters in each virtual unit, obtaining a strategy of a parameter set of each virtual unit, and obtaining a
power optimization scheduling variable reduction strategy of each virtual unit; a complex power
system is decomposed into a plurality of virtual units with similar characteristics, the number of decision variables can be effectively reduced, so that the complexity of a problem is reduced, the problem is easier to manage and solve through simplification, the overall optimization efficiency can be improved, the
processing efficiency can be further improved, each module is endowed with a
specific function, and the method is suitable for large-scale popularization and application. Therefore, the method has the advantages that the
power optimization scheduling variable is reduced, the problem scale is reduced, and the solving is accelerated.
