Impacts of distribution network characteristics on penetration level of wind distributed generation and voltage stability

Analysis of the effects of wind distributed generation (DG) on voltage stability of distribution networks is presented in this paper. A test system which is consisting of a wind farm connected to a distribution network is studied. Simulation studies are carried out using MATLAB-Simulink software. The results show the effects of different factors such as short circuit capacity and network reactance to resistance ratio of distribution system on its voltage stability and the critical values for the parameters can be determined.
