Time-sequential simulation technique for rural distribution system reliability cost/worth evaluation including wind generation as alternative supply

Abstract

Wind turbine generators (WTGs) are being actively considered as embedded generation sources in rural distribution systems. A time-sequential simulation technique is presented for the reliability cost/worth evaluation of a distribution system including WTGs. A three-state model of a WTG is presented, considering variable wind speed and the forced outage rate. A test rural distribution system is utilised to illustrate the proposed technique. The system reliability performance using WTGs as an alternative supply is investigated. The effects on the distribution system reliability of the WTG parameters are examined and illustrated.
