The influence of wind farm group topology structure on power flow distribution

The wind energy resources are rich and concentrated in China, and many wind farms often distribute in one windy area. These wind power should be gathered through the appropriate topology so that they could be sent to the electricity grid. This paper mainly compares several common different wind power collection systems. And on this basis, we use the PSD - BPA power system analysis software to analyse a wind power group with 12 wind farms, mainly focusing on the difference of the distribution of the power flow under different topologies. Besides, we will also compare the difference of the output with the wind speed change and other situations under different topologies.
