具有灵活、清洁、安全、经济、友好等性能的智能电网是未来电网的发展方向。首先介绍了智能电网的概念和功能特点，详细分析了国内外智能电网的研究进展，对重点关键技术与智能电网的关系进行了分析和讨论，指出基于Agent的分布式协调、控制、仿真与决策技术，分布式能源的系统集成以及基于知识的综合决策支持是未来智能电网技术发展的重要方向。中国特色智能电网的建设是一项高度复杂的系统工程，为此文章提出了积极有序地推进智能电网研究及建设的具体建议，包括：发挥一体化管理优势；开展我国智能电网架构设计；制定试点方案及实施计划；发输配用电的协调安全与经济运行；注重理论和技术创新与应用；统筹考虑电网规划、建设、改造和技术升级等。

The future development trend of electric power grid is smart grid, which include such features as flexible, clean, secure, economic, friendly and so on. The concept and function characteristics of smart grid are introduced in this paper firstly; then the progress of research on smart grid home and abroad as well as the relation between key technologies and smart gird are analyzed in detail, and it is pointed out that the Agent based distributed cooperation, control, simulation and decision-making, system integeration of distributed enengy, knowledge based comprehensive decision support are the key development trend of smart grid in future. The construction of smart grids in China is a very complicated system engineering, for this reason some concrete suggestions are made, such as fully taking advantages of integrated management, carrying out architectural design of smart grids in China; drafting pilot plans and implementation schemes; coordinating secure and economic operation of power generation, transmission and distribution; paying special attention to theoretical and technological innovation and application; overall considering the planning, construction, renovation and technology upgrating of power grid, to push the research and construction of smart grid in China actively and orderly.
