坚强智能电网发展技术的研究

Study on the development and technology of strong smart grid

针对目前电力运行环境的日趋复杂、电力体制改革的不断前进、电力市场的逐步行成、现有的电力设备亟待更新、能源利用率低、电能质量差、用户与电网公司交互作用少等诸多问题,讨论了适合中国电网情况的智能电网的定义,总结出了智能电网自愈、互动、优化、兼容、集成五大特点,概括出了智能电网和传统电网的区别,并详细介绍了构成智能电网的四大体系和建立智能电网的两大基础,最后总结出智能电网是经济和技术发展的必然结果,我国应加快智能电网的研究发展。

For the current situations that electrical power operation environment is more complex, the power organization reform constantly, the electricity market is formed step by step, the current electrical equipment is outdate, and for the so many problems that low energy efficiency, poor power quality, less interaction between customers and power grid company, this paper defines the smart grid that is suited to China＇s power grid situation, and summarizes five features for the smart grid such as self-healing, interactive, optimization, compatibility, integration and the differences between smart grid and traditional grid, then introduces the four systems of smart grid and two foundations before building the smart grid, and finally concludes that smart grid is the inevitable result for the economical and technological development. China should speed up the research and development for smart grid.
