Analyses and Suggestions on Current Development Status of Smart Power Transmission Systems in China

In view of the characteristics, such as highly compatible power access capability, high security and reliability, and great flexibility and controllability, the application of smart grids in power transmission systems will improve both operation security and stability of power grids in China. Based on the development conditions of the Three-Hua UHV synchronous power grid, which connects North China, Central China and East China Grids, the necessity of applying smart grids to large-scale interconnected power systems in China is analyzed, the current development status of smart grids in domestic power transmission systems is reviewed, and suggestions on the development of smart grids in China are provided.
