Example of the planned total power generation of a solution over the time horizon for the case study (red line) in comparison with the planned day-ahead bids b _t (x) (blue horizontal hatched area) and with commitments c(t) (green diagonal hatched area). The vertical dashed line represents the beginning of the time horizon on 2014-04-26 at 12:00 (local time). The vertical grey lines separate the days of the time horizon. For reasons of confidentiality, the power values are arbitrarily scaled.
