The invention discloses a power
system end-to-end unit
combination method of an object number fusion driving space-time attention graph neural network. The method comprises the steps of obtaining operation data of a power
system; constructing a space-time self-attention graph
convolutional neural network, and constructing a unit commitment model based on the space-time self-attention graph
convolutional neural network; operation data of a power
system are input into a unit combination model for two-stage model training, and in the first stage,
model parameter initialization is guided based on a physical mechanism, integer variable local relaxation and supervision pre-training fusion strategy; in the second stage, target guidance, physical mechanism constraint and integer variable local relaxation are adopted to realize secondary adjustment of
model parameters; introducing an adaptive penalty term updating
algorithm to obtain a trained unit commitment model; and realizing a unit commitment decision of the power system based on the trained unit commitment model. According to the method,
time sequence and space constraints in the unit commitment problem can be effectively processed, and end-to-end unit commitment rapid decision is realized.
