The invention discloses an electric energy and peak regulation auxiliary service market combined clearing method and system. The method comprises the steps of obtaining operation constraints of multiple types of subjects; a day-ahead electric energy pre-clearing model is established, when the clearing result of the day-ahead electric energy pre-clearing model does not meet the requirement of new energy consumption, a peak regulation-electric energy combined clearing model is established, and a direct current model and a safety constraint unit combination are adopted to aim at minimizing the market electric energy cost and the peak regulation cost. The generated unit start-stop state serves as a boundary condition of safety constraint economic dispatching, a Lagrange function is constructed according to a result of safety constraint economic dispatching, the marginal electricity price of an electric energy node is solved, and meanwhile the peak regulation marginal price of each time period is determined accord
