Security and Stability Analysis for Yunnan Power Grid with Wind Power Integration

Wind power is sustainable, renewable and clean energy. There are abundant wind resources in Yunnan province, China. In recent years, wind power integration has developed rapidly in Yunnan province. With the first batch of the wind farm being built and a part of them going into production in Yunnan, the wind power resources will be large-scale developed and utilized in the future. Based on the wind power planning of Yunnan, the impacts of security and stability after wind power are studied in this paper. The major researches are made on the capacity analysis for accessing high-capacity wind farm, the analysis for power system voltage stability and comparison of different windgenerator model structures, thus finding out the most suitable choice for fan selection in Yunnan Power Grid.
