Research on Power System Dynamic Stability in Smart Grid

After decades of efforts, great progress has been made in theory and practice. The power system itself has strong complexity and professionalism. This determines the particularity of power communication system. With the deepening of research, the dynamic nature of voltage stability has attracted people's attention. People gradually realize that in order to fundamentally explain the mechanism of voltage instability, it is necessary to establish the dynamic model of power system. At the same time, according to wide area information and power grid response, it will form control strategy on the basis of stability judgment to complete stability control, control process The mode is different from the past. To a great extent, smart grid has effectively changed the state of traditional power system, and applied many new technologies to relay protection technology. This paper mainly analyzes the dynamic stability of power system in smart grid environment.
