Discussion of Wind Farm Integration in China
Summary form only given. There are a number of issues need to be studied regarding the wind farm integration. The comparatively long distance transmission of wind power must to be considered because the regions with abundant wind resources and other proper conditions suitable for large wind farms construction are in the periphery of the grid, far from the load center. In general the regional network integrated with wind farms are not very strong, some problems such as voltage, power system stabilities and power quality arise when large wind farms integrated into the grid. Therefore it is necessary to do thorough studies on wind power integration. This paper carries out a regional wind power integration study of an actual power system in Jilin province of north China, presents the mutual interaction between the power system and wind farms by simulation. It includes the contents below: the impact on local grid voltage level both with the different power output of the wind farms and during the cut-in and cut-out process; transient stability changes of the grid integrated with large wind power and impact on the neighboring grid; the wind farms operational performance during the contingency of power system. Finally, it describes the mechanism of the results and discusses some issues related to wind power integration
