The invention belongs to the technical field of
power system automation, and provides a self-adaptive
tensor decomposition attention mechanism for a
virtual power plant and a prediction optimization method thereof.The method comprises the steps that firstly, multi-
modal data such as historical loads and weather of the
virtual power plant are collected, and preprocessing such as normalization and
feature extraction is conducted; then, an adaptive
tensor decomposition attention network is built based on the processed data, an improved Xavier method is adopted to initialize a core
tensor, features are fused after multi-
modal data are coded, and a load prediction model is built through adaptive
tensor decomposition attention calculation; and finally, adaptive core tensor updating is executed, through optimization strategies such as Hessian matrix low-rank approximation, adaptive sparse
mask generation and Nesterov acceleration
momentum calculation,
batch processing and parallel calculation, adaptive
resource allocation and core tensor updating are combined, data calculation is input, and a load prediction result is obtained. The objective of the invention is to solve the problems of high attention mechanism calculation complexity, parameter redundancy, low multi-
modal data fusion efficiency, insufficient load sudden change period prediction precision and lack of an adaptive
resource allocation mechanism in the existing
virtual power plant load prediction technology.
