摘要
资源和环境的双重压力给电力系统带来了新的挑战。为应对这些挑战,国外研究者提出了智能电网的概念,并已有了初步实践。文中在对国外智能电网实践进行分析、总结的基础上,提出了智能电网的定义,认为是否具有"多指标自趋优运营能力"是智能电网与传统电网的最大区别,而如何使电网具备"多指标自趋优运营能力"则是智能电网研究和实现过程中所要解决的关键问题。
Double pressures from resources and the environment bring new challenges to the power systems.To face these challenges,the overseas researchers propose the conception of smart grid and have tentative practices on this field.Based on the analysis and summary of the smart grids practicing,the definition of the smart grid is given,and the ＂ability of multi-indices self-approximate-optimal operation＂ is taken as the most distinctive difference between smart grid and traditional grid.How to enable the grid to have this ability is the key point which must be solved in the process of smart grid research and design.
