Method and system for calculating and sharing cost of standby auxiliary service, and storage medium

The invention discloses a standby auxiliary service cost calculation and allocation method and system and a storage medium, and the method comprises the steps: obtaining a fluctuation component covariance matrix according to the historical data of a new energy unit and a load; establishing an opportunity-constrained single-period standby electric energy product combined clearing model; the opportunity-constrained single-period standby electric energy product joint clearing model is converted into a convex second-order cone programming problem, and the output value and the response coefficient of the thermal power generating unit in each period are obtained after solving; listing a Lagrangian equation of a convex second-order cone programming problem, and calculating the auxiliary service apportioned cost of the new energy unit and the load by solving a corresponding constraint Lagrangian multiplier and extracting an error standard deviation value from a fluctuation component covariance matrix of the new energ
