Due to the increasing penetration of wind energy in nowadays power grids, the accurate wind speed prediction (WSP) is critical to more efficient and reliable operations of power systems containing wind turbines. This paper presents a novel deep attention convolutional recurrent network with K-Shape and enhanced memory (DACRN-KM) for more accurate short-term WSP. To well capture spatial-temporal information among wind speeds measured across the wind farm, a DACRN is firstly developed to extract latent representations. Next, an auto-update memory module is developed to rebuild latent representations based on historical records. A K-shape clustering algorithm is applied to derive K patterns of rebuilt latent representations and the final prediction layer (FPL) is developed to generate the WSP result for latent representations assigned to one out of K patterns each time. The effectiveness of the proposed DACRN-KM is validated with data collected from 25 wind turbines (WTs) in multiple wind farms, in which a part of them is publicly accessible, by benchmarking against a set of the commonly considered and recently reported methods.
