Total Transfer Capability Analysis in Power System including Large-scale Wind Farms

Wind power industry is developing rapidly, more and more wind farms are being connected into power systems. In this paper, a calculation model of continuation power flow in power system containing large-scale wind farms is established by using the detailed pi-type equivalent circuit of asynchronous wind turbine. Based on the proposed method, total transfer capability (TTC) is investigated under the static voltage stability constraint. The analysis results show that both the compensation capacity of wind turbine terminals and wind speed have a great influence on TTC
