Abstract: Xiangxi  is the main power source of Hunan Province. The stability of Xiangxi regional power grid is affected by the seasonal  hydroelectric power generation and the  wind power generation. In order to improve the stability of Xiangxi regional power grid, the superconducting magnetic energy storage (SMES) system is connected to provide real-time and rapid power support to the power grid, so as to solve the instability problem caused by system failure or new energy access. We build an equivalent simplified model in power system analysis software package and simulate the disturbance of the power grid. Then we connect the superconducting magnetic energy storage system in above model, and analyze its positive impact on the stability of the system through the changes of the power angle and voltage of the system.

Key words: superconducting magnetic energy storage, Xiangxi power grid, transient stability, power system analysis software package
