Varying penetration ratios of wind turbine technologies for voltage and frequency stability

Paper presented at the IEEE Power and Energy Society 2008 PES General Meeting - Conversion and Delivery of Electrical Energy in the 21st Century, 20-24 July 2008, Pittsburgh, PA, USAThis paper examines the ability of a power system to accommodate wind generation with varying ratios of doubly fed induction generator and fixed speed induction generator turbines from both static and dynamic aspects. By controlling the ratio between the two types of turbines, voltage stability is maintained for steady-state conditions for a large range of varying wind speeds. Using the ratio determined from the static analysis, the dynamic analysis explores the voltage and frequency characteristics of the system under contingency conditions. An initial analysis was carried out on the IEEE 30 bus test system. The results of this analysis are presented in this paper and detail how by varying the ratio of the turbine types the frequency stability and voltage stability can be improved.Science Foundation IrelandConference websitehttp://ewh.ieee.org/cmte/PESGM08/Charles Parsons Energy Research AwardsCharles Parson au, pe, la, ke, ab, - kpw22/12/1
