Electric power spot clearing scheme optimization method and device, computer equipment and medium

The invention relates to an electric power spot clearing scheme optimization method and device, computer equipment and a medium. The method comprises the following steps: according to power data uploaded by each level of power dispatching system, generating a security constraint unit commitment SCUC model and a constraint condition of the SCUC model, dividing the SCUC model into a plurality of sub-models according to a plurality of preset time periods, and aiming at each sub-model, utilizing the constraint condition and a Lagrange multiplier to generate a security constraint unit commitment SCUC model; obtaining a calculation result of the sub-model; the calculation result represents an optimal power clearing scheme corresponding to each time period, and obtaining a solving result of the SCUC model according to the calculation result of each sub-model; the solving result represents an optimal power clearing scheme determined according to the power data. By adopting the method, the efficiency of determining th
