Two-phase Short-term Scheduling Approach with Intermittent Renewable Energy Resources and Demand Response

Neglecting input power from renewable energy sources in the unit commitment can lead to excessive commitment of fossil generation, inefficient use of committed power and potential reliability problems. In this paper, a two-phase short-term scheduling with intermittent renewable resources and storage methodology is presented. The first-phase is the day-ahead model which determines the unit commitment operational decisions and feeds them into the second-phase which is a real-time economic dispatch. Perfect forecasting for renewable energy sources is considering besides customer based line is used for demand forecasting. A case study is presented to illustrate the application of the proponed methodology.
