Discussion on the development trend of smart grid and its key technology

Smart grid technology will fundamentally change the current distribution and electricity way, it not only helps to reduce the power demand, cost savings, but also can significantly improve power system reliability and efficiency. Smart grid using the new network technology, including can be used for real-time monitoring of power using a sensor and can be used to automatically change to reduce power consumption controller. However, the smart grid also brings security and privacy, large-scale distributed sensor management system and other complex issues. This paper introduces the concept of smart grid and functional characteristics of smart grid technology, summed up the research situation at home and abroad and the significance of developing smart grid. Based on the analysis of the smart grid, smart grid will be the development trend of modern power system. At the same time on the smart grid technology are reviewed in this paper, cited several key technologies of smart grid technologies, and points out the problems and challenges.
