Operational Impact and Cost Analysis of Increasing Wind Generation in the Island of Crete

This paper presents the methodology and the results of a study for determining the operational impacts and integration costs of high penetration of wind generation on various types of ancillary services and unit commitment scheduling for isolated systems. The methodology has been applied on the Greek Island of Crete. Three years of minute-by-minute telemetered load, wind speed, and wind generation data were deployed. This paper also analyzes the operational impact of curtailing excess wind for security purposes.
