METHOD FOR ANALYZING MULTI-TEMPORAL GRID OPERATION TRACE BASED ON DIGITAL TWINS

The present invention discloses a method for analyzing multi-temporal grid operation trace based on digital twins, including: S1 performing feature reduction on a set of original power grid sample data; S2 based on the set of original power grid sample data with performed feature reduction, building a power grid digital twin model; S3 based on the set of original power grid sample data with performed feature reduction, building a model for simulating multi-temporal power grid operation trace; and S4 generating trace data based on the power grid digital twin model, and inputting a hybrid dataset composed of the trace data and real-time data into the model for simulating multi-temporal power grid operation trace for analysis and assessment. By way of comprehensively analyzing multi-temporality, the present invention makes it possible to fully understand operation states of power grids and provide a scientific basis for scheduling power grids and decision-making.
