Voltage Stability Analysis of a Distributed Network Incorporating Wind Power Resource

Abstract

This paper investigates the impacts of a wind farm connected at Harterbeespoort substation in South Africa on voltage stability of the power network. The site wind speed was determined and analyzed for viability. A comparison is made between the use of Doubly-Fed Induction Generators and Self-excited Induction Generators driven by the wind turbines. The resulting P-V and Q-V curves from load flow studies are presented and analyzed. The models for this study were implemented in DigSILENT PowerFactory.

Voltage Stability Analysis of a Distributed Network Incorporating Wind Power Resource

“…As a consequence of this, the voltage control assessments and reactive power compensation are vital factors to consider when planning for development of large-scale wind power integration. The choice of the wind farm site and accurate estimation of wind speed variability over time is equally important (Juma, Mochusi, Munda, & Jimoh, 2010).…”
