The invention relates to the technical field of electric power spot market clearing, in particular to an electric power spot market clearing method and system, and the method comprises the steps: obtaining full electric quantity clearing input data of all provinces in a region; and inputting the full electric quantity clearing input data of all provinces in the region into a pre-constructed clearing model to obtain a clearing result. Wherein an objective function is configured in the clearing model; the objective of the objective function is to minimize the sum of the total power generation cost and the total trans-provincial power transmission cost; the constraint condition of the target function at least comprises a trans-provincial power transmission power flow constraint, a power transmission component and a correlation constraint of a physical line. According to the technical scheme, the spot market range is expanded from an independent province to the whole area, the full electric quantity of the cleari
