Impacts of fixed speed wind generators on static voltage stability of distribution systems

Abstract

More and more small-scale wind generators are being connected to distribution systems. Higher degree of penetration of wind generators can significantly change many operating characteristics of the system including voltage profile and hence voltage stability. This paper proposes a straightforward method of static voltage stability assessment of a radial distribution system with fixed-speed wind generators. Time varying system demand and measured wind data over a period of one year are considered. The effectiveness of the proposed method is then evaluated on a 12.66-kV radial distribution system consisting of 32 buses and the results obtained are systematically described.
