智能电网支撑智慧城市关键技术

Review of Key Technology of Smart Grid Supporting Smart City Construction

智能电网对智慧城市建设具有强大的支撑潜力。阐述了智慧城市的内涵与特征,及其对智能电网的关键需求。通过梳理二者的关系认为智能电网是智慧城市的重要组成部分,以智能电网为基础构建智慧城市是智慧城市发展的重要途径。在智能电网建设中,需要深化应用信息通信类技术、分布式能源发电并网技术、绿色输变电工程技术、先进储能技术、主动配电网和微网技术、需求响应技术、电动汽车与电网互动技术、智能用电及用户用能行为分析技术、智能电网业务互动技术城市能源互联网等关键技术,使智能电网为智慧城市的发展提供强大的支撑。

Smart grid has great supporting potential for smart city construction. This paper describes the connotations, characteristics of smart city and its key demands for smart grid. It is pointed out that smart grid is an important component of smart city after a careful study of the relationship between smart city and smart grid. It is the important way to develop smart city by constructing smart city based on smart grid. The key technological problems to be solved for the development of smart grid reside in fields of information and communication teehnology （ICT）, distributed generation （DG） integration, energy storage, active distribution network （ADN）, demand response （DR）, electric vehicle to grid, energy internet etc. It is concluded that the smart grid will effectively promote smart city construction.
