Assessment and economic analysis of wind generation on the ancillary services and the unit commitment process for an isolated system

Abstract

This paper analyzes the behavior of the wind and examines the impact of varying levels of wind penetration on the ancillary services and unit commitment costs for conventional oil-fired generation for an isolated system. The application is based on data for the island of Crete. Three years of minute-by-minute telemetered load, wind speed, and wind generation data were deployed. The study also analyzes the operational impact of curtailing excess wind for security purposes.
