With the need for the construction of smart grid to intelligent power as a starting point, the key technologies and new services for intelligent power are studied and a communication network scheme of bidirectional interaction information service system in smart grid is designed. The system provides a reliable information access and network support for the interaction between grid and user by using advanced bidirectional interactive communication technology, intelligent interactive terminal, and smart meter technology. It also puts forward a building program about information interaction platform in application layer to establish new power supply and demand relationship between grid and users. The scheme can not only support the demand of users for three networks convergence, smart home, community services, but also satisfy the requirement of advanced technology, energy saving, service diversity, and friendly interaction for intelligent power.%以建设智能电网对于智能用电的需求为出发点，研究了智能用电的关键技术以及智能用电新型服务，针对不同的用户设计了面向智能电网的双向互动信息服务系统以及通信组网方案。采用先进的双向互动通信技术、智能交互终端技术以及智能表计技术，为电网和用户之间的互动提供可靠的信息通道和网络支撑，并对应用层信息互动平台提出建设方案，构建了电网与用户之间信息、能量、业务实时互动的新型供用电关系。所提方案支持用户对三网融合、智能家居、社区服务等增值服务的需求，满足智能用电对技术先进、节能减排、服务多样、友好互动的要求。
