The invention discloses a
power system scheduling and optimizing method and
system based on a multi-
granularity tree diagram neural network. The method comprises the following steps: step 1, constructing a
power grid state sample
data set; 2, performing graph representation and
feature extraction on the
power grid data; step 3, constructing a hierarchical multi-
granularity power grid information coarsening model; 4, constructing a power grid information graph disturbance model; step 5, constructing a tree neural network adaptive path selection model; and step 6, according to the multi-
granularity tree neural
network model, executing explanation and scheduling decisions of the power
system. According to the method, graph
network structure characteristics of a power
system are considered, a power grid is modeled into graph data, and on the basis of an existing graph neural
network model, a multi-granularity graph coarsening module, a learnable disturbance module and a self-adaptive path selection module are introduced to construct a tree-shaped model of a multi-layer structure; therefore, the state and representation of the power system of each granularity level, such as global and
local scale in different ranges, are analyzed, and the prediction accuracy of the model and the
interpretability of the decision are improved.
