With the expansion of the pilot area of the electricity spot market in China, how to consider the conditional section to clear the spot market is a new problem faced by dispatching operators. This paper first analyses the impact of conditional section constraints on the clearing of the spot market. Secondly, in order to improve the efficiency of spot market clearing calculation, based on the mode of posterior addition, a fast method of checking condition section is proposed. Thirdly, this method is incorporated into the framework of day-ahead spot market clearing. Finally, the validity of the method is verified by an example analysis of the IEEE118-node system.
