Current practice is described and contrasted against the new requirements. Literature specifically addressing questions about wind power and unit commitment related power system operations is surveyed. The scope includes forecast errors, operating reserves, intra-day markets, and sharing reserves across interconnections. The discussion covers the critical issues arising from the research.1298973 bytes1072 bytesapplication/pdftext/plainen© 2011 IEEE. Personal use of this material is permitted.
