Impact of density of wind turbine induction generator on static voltage stability of distribution network

In this paper the impact of wind turbine induction generator is analysed. At first, the index of static voltage stability that can be used to measure the static voltage stability of nodes and distribution network is worked out. Then the factors that can influence the index of static voltage stability are analysed. At last, conclusions of this paper is got by the simulation result of IEEE 33-bus test system: wind turbine can provide voltage support for nodes; high density and large amount of high density nodes can increase the static voltage stability index of distribution network.
