Wind power forecasts for look-ahead times of 0-48 hours provided at
times t, t-6, t-12 and t-18 hours
The output of the wind power forecasting model is the wind power forecast,
which typically provides hourly predictions for look-ahead times up to 48 hours.
The forecasts can be provided for specific wind farms, for a portfolio of wind farms
or for all wind farms in a particular region or supply area. In Figure 6.13, four sets
of successive wind power forecasts for a group of wind farms (at t , t -6, t -12 and
t -18 hours) are overlaid, together with the measured power. The forecasts are for
look-ahead times in the range 0-48 hours.
