Research on the market mechanism of energy storage participating in Electric Auxiliary Services

The development of energy storage technology and policy support have promoted its deployment on a global scale. With the continuous expansion of the installation scale, the business model of energy storage has become increasingly diversified and its application scope has gradually expanded. Energy storage is widely used in the field of power auxiliary services. In this paper, the feasibility of independent energy storage operators to provide single or multiple auxiliary services and distributed energy storage operators to participate in electric auxiliary services is reviewed. The collaborative sharing mechanism and aggregator mechanism of distributed energy storage are studied. Finally, the next research direction of distributed energy storage participating in electric auxiliary service is prospected.
