The invention relates to the field of electric vehicle charging station optimization operation, and discloses an electric vehicle charging station commutation response method comprising the following steps: obtaining basic operation parameters of a power distribution network and a charging station, and building a power distribution network three-phase optimal power flow model based on an AC optimal power flow; establishing a charging station commutation operation optimization model taking the minimum electricity purchase cost as a target; based on the three-phase optimal power flow model of the power distribution network and the charging station commutation operation optimization model, establishing an interaction mechanism of electricity price clearing power adjustment between the charging stations of the power distribution network; and solving the interaction mechanism to obtain the number of the charging piles in the charging station distributed on each phase of the alternating-current three phases, so that the lowest electricity purchasing cost of the charging station can be realized. Under the excitation of the three-phase DLMP of the power distribution network, the commutation operation of each charging pile is optimized, and the operation cost of the power distribution network is reduced while the power purchase cost of the power distribution network is reduced.
