Technical Challenges of Increasing Wind Power Penetration into a Small Power System

High penetration of wind power in a power system means that dispatchable conventional generating units and their primary voltage control capability are displaced by nondispatchable wind power. Integration of large-scale wind power into a small system such as the Tasmanian power system has significant implications for frequency stability, transient stability, voltage stability, short circuit levels and supply-demand balance, because the characteristics of wind turbines are different from those of conventional power plants. This paper examines the technical issues limiting the scope of integrating large-scale wind generation based on double fed induction generation technology into a small system.
