More and more large capacity wind power will be integrated into power system in the future, and certain technical challenges will emerge due to the fluctuation characteristics of wind power and the complex control of power electronic devices inside the wind turbines (e. g., low voltage ride through (LVRT)). By comparing a wind power integration grid with a hydropower integration grid, the special transient phenomena caused by the wind power integration is studied and simulation results are presented. Furthermore, the potential impacts on the traditional protection are discussed. Results show that the special transient phenomena can decrease the sensitivity, reliability and operation speed of conventional protections.
