The invention discloses a method for assessing the effectiveness of an energy storage system in response to the frequency adjustment demand of a high-wind power permeability system. The method is characterized in that the proportionality coefficient KP of the energy storage system in participation in frequency adjustment is selected through an analytic hierarchy process according to established indexes for evaluating the energy storage system in response to the frequency adjustment demand of the high-wind power permeability electric system, an auxiliary service pricing mechanism for energy storage power stations of different types in participation in frequency adjustment of the electric system is studied and established by comprehensibly considering benefit factors such as the energy storage system party and the power grid party, and the wind power receptivity of existing power grids and system operating safety are improved. The method has the advantages of being scientific, high in applicability, good in effect and the like.
