Study on protection of large scale wind power integration

It is apparent that more and more large capacity wind power will be fed 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 electronics devices inside the wind turbines (e.g. Fault Ride Through - FRT, etc). By comparing one wind power integration grid with one hydropower integration grid, the special transient phenomena caused by the wind power integration is studied and the simulation results are presented in this paper. Furthermore, the potential impacts on the traditional protection are discussed in this paper. The study results show that the special transient phenomena may decrease the sensitivity, reliability, and operation speed of conventional protections.
