The invention is suitable for the technical field of short-term
power load prediction and intelligent scheduling, and provides a short-term
power load prediction method based on improved
sparrow search algorithm (ISSA) optimization. The method comprises the following steps: constructing a multi-scene prediction task according to the
time resolution and regional seasonal characteristics of a load; local features are extracted in combination with a
convolutional neural network (CNN),
time sequence dependence is modeled by a long short-
term memory (LSTM) network, and an attention mechanism is introduced to strengthen key features; meanwhile, an ISSA is adopted to optimize a
model network structure and hyper-parameters, the number of
layers, the learning rate and the batch size of the CNN and the LSTM are adjusted in a self-adaptive mode, and the search efficiency and convergence performance of the ISSA are improved through Latin
hypercube sampling, cosine annealing, dynamic spiral search and a Levy flight strategy.
Simulation results show that the method can maintain high prediction precision under different time resolutions and regional and seasonal conditions, the generalization ability and cross-scene adaptability of the model are enhanced, and a stable and efficient load prediction scheme is provided for
power grid dispatching optimization.
