Incorporating wind energy on a large scale into power systems presents challenges for the operation and control of grid. To enhance safety grid operation, accurate short-term forecasting is necessary, as it minimizes impact randomness. Considering uncertainty prediction issues associated with power, this paper introduces CNN–GRU ultra-short-term model. This model relies multichannel signals, including data such speed, direction, climate conditions, historical outputs collected from farms....
