[0051] Such as figure 1 As shown, the present invention discloses a load forecasting method based on dynamic time warping and long and short time memory. The idea of the present invention is to first cluster power users based on dynamic time warping similarity, and gather users with similar power usage habits. Into one category. Then perform random pooling operations on users of the same category to increase the scale and diversity of training data to increase the generalization ability of the prediction model. Then, the pooled user data sets are respectively established based on long and short-term memory load forecasting models. The proposed method has better engineering adaptability.
[0052] Because the user's load curve has the characteristics of multilaterality and time delay, there is a certain deviation in the clustering of load users based on Euclidean distance, which cannot be judged. Dynamic Time Warping (DTW, dynamic time warping) is a method to measure the simila...
