The invention relates to the technical field of power system planning and design, more specifically relates to a peak shaving right transaction method for promoting clean energy consumption. The invention provides a peak shaving right transaction method for promoting clean energy consumption. According to the method, a sending-end buyer profit economic model, a cost model and a receiving-end seller peak regulation cost model are established, a multi-objective genetic algorithm optimization model with maximum social benefits and maximum consumption of clean energy is further constructed, and peak regulation transaction capacity with the optimal social benefits and unified clearing prices of buyers and sellers are obtained through model solving.
