Method and system for establishing clearing process of power market

The invention relates to a method and system for establishing a clearing process of a power market, and the method comprises the steps: solving a unit combination integer variable according to a prediction load, a system topological structure, a unit reporting parameter and cost, and determining an optimal DC power flow clearing result at a scheduling stage; based on a preset model, carrying out market verification on the optimal direct-current power flow clearing result in the scheduling stage and acquiring a result that market verification does not pass, wherein market verification comprisesN-1 safety verification and alternating-current feasibility verification; constructing an in-field correction model and an out-of-field correction model according to the result that the communicationfeasibility verification is not passed; adopting the mode of determining the economic influence of the in-field correction model and the off-field correction model on the market operation cost, the market members and the mark
