Multi-indices self-approximate-optimal smart grid

Abstract

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. © 2009 State Grid Electric Power Research Institute Press.
