... large-scale wind energy in a power system.
The focus is on wind power forecast updates (paragraph 3.2.1), aggregation of wind power
(paragraph 3.2.2), energy storage (paragraph 3.2.3), and wind farm ... with short-term wind power forecasts.
The proposed intelligent IOPAC is therefore shown to alleviate imbalances due to wind
power forecast errors.
