Effect of distribution system specifications on voltage stability in presence of wind distributed generation

摘要

Increasing penetration of distributed generation and renewable energy such as wind farms due to various reasons including environmental and economic causes, decentralization and limits on fossil fuels increased the effects of DG on power systems. This paper presents a wide analysis of the effect of wind distributed generation (DG) on voltage stability of distribution networks. Wind farms with having induction generators, are suffering from some voltage stability problems. A test system consists of a wind farm connected to a distribution network is studied. Simulation studies are carried out using MATLAB SIMULINK software. The results show the effect of different factors such as network short circuit capacity and network X to R ratio on voltage stability of the system and the Critical values for the parameters could be determined. There is also a comparison between induction and synchronous generators in a same capacity on voltage stability problem.
