Research Status and Development Trend of Smart Grid

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.
