Statistical Quantification of Voltage Violations in Distribution Network with Small Wind Turbines

This paper develops a statistical methodology to identify the probabilities of when and where the voltage violations occurring in residential, industrial and commercial areas respectively with cumulative penetration of SWTs. The proposed methodology is applied to a typical U.K. distribution network model, and results indicate that industrial and commercial weekends have the highest probabilities of voltage violations, and voltage violations are more likely to occur on residential weekdays and weekends than that of industrial and commercial weekdays.
