A Modified Unit Commitment and Generation Control for Utilities with Large Wind Generation Penetrations

A modified unit commitment is proposed in this paper that would be updated on three different cycles (daily, quarter-hourly and every minute). The 24 hour updated unit commitment would include the effects of load and slow trend wind power change that could be predicted 24 hours ahead. The quarter- hourly updated unit commitment would handle the fast trend and cyclic change in wind power that could be predicted one hour ahead and would commit peaking, regulation, and quick pickup and possibly economic units to handle these wind power changes.
