The invention discloses an E-SOP
optimal scheduling method and
system based on unscented transformation and an
information gap decision theory, and belongs to the field of E-SOP
optimal scheduling. According to the method, historical data are obtained, unscented transformation is used for carrying out joint uncertainty modeling on loads and
new energy output, fluctuation characteristics and correlation of the loads and the
new energy output are captured, and the unscented transformation and the
new energy output are combined; and performing
information gap uncertainty modeling on the price cost of the
transformer substation market by using an
information gap decision theory, quantifying the maximum tolerance of the
system to the
price fluctuation, finally comprehensively representing the characteristics of source-load random fluctuation and price interval fluctuation, solving a function taking the minimum operation cost as an objective function, and obtaining an optimal E-SOP regulation and control strategy. Cooperative
processing of source load randomness and
price fluctuation is realized, scheduling accuracy of the E-SOP is improved, and the problem of low scheduling accuracy of the E-SOP caused by incapability of cooperatively
processing source load randomness and price information gap uncertainty due to independent
processing of a certain type of uncertainty in the prior art is solved.
