The invention provides a standby and peak shaving auxiliary service cost allocation method facilitating new energy grid-connected consumption. The method comprises the steps that a target function and constraint conditions of a new energy grid-connected consumption model based on production simulation are determined; the standby auxiliary service cost spent after new energy grid connection is calculated; new energy wind turbine generator earnings are calculated; the standby auxiliary service allocated cost is calculated; the peak shaving auxiliary service allocated cost spent by wind power connection is calculated. According to the standby and peak shaving auxiliary service cost allocation method facilitating new energy grid-connected consumption, the consumption model taking the extra service cost spent by new energy grid connection into account is built, the standby and peak shaving auxiliary service cost spent by new energy in different situations is analyzed, and therefore the allocation scheme for the auxiliary service cost spent after new energy grid connection is provided; service providing initiative of a traditional power source is effectively improved, the benefits of a provider are ensured, wind or light abandoning is reduced, and economical operation of a system is ensured.
