To explore a new mechanism of frequency response with multi-resource coordination, a day-ahead and intra-day decentralized mutual-aid method of energy and auxiliary services is proposed. Firstly, based on the mutual-aid of energy resources, the framework of multivariate adjusting resources is established including day-ahead and intra-day energy, inertia and primary frequency regulation （PFR）. Secondly, the shared alternating direction method of multiplier（ADMM） is adopted to realize efficient solutions of the model and protect the privacy of mutual-aid subjects, in which the alternating optimization procedure （AOP） is established to address the non-convexity. Finally, a simulation example is given to verify that the proposed method can effectively motivate multiple regulatory resource suppliers to provide inertia and PFR services, which provides a reference for promoting mutual-aid of frequency regulation resources.
