The reliability of massive power services under the energy Internet needs to be guaranteed and to avoid the impact of poor communication quality and interruption during service transmission. In this content, this paper analyzes the traditional transmission mechanism and existing problems of power services under the existing energy Internet. The terminal point-to-point and on-site server point-to-point interaction mode is designed to clarify the interaction process of side-to-side collaboration. The side-to-side collaboration can ensure that when the power grid business is affected by network faults or uncertain factors, the service information can be uploaded or localized through the edge agent, or the information can be transmitted through the interconnection between terminals. This paper analyzes the point-to-point interaction model under the side-to-end collaboration and the side-to-end coverage model. On the basis of related models, the simulation services operation situation and reliability optimization effect are simulated. The simulation analysis shows that the side-end collaboration mechanism proposed in this paper can improve the reliability of the services.
