Running standby partition optimization method and device

The invention relates to an operation standby partition optimization method and device, and the method comprises the steps: obtaining historical operation data, and calculating the time-of-use electricity price of each load node according to the historical operation data; sorting the time-of-use electricity prices of the load nodes according to a time sequence to obtain a node time-of-use price vector; constructing a node similarity matrix according to the node time-sharing price vector; determining a reference node according to the node similarity matrix; and according to the similarity and the difference between the reference node and the load node, determining the operation standby partition of each load node. According to the method, the time-of-use electricity price vector of each node is constructed by using historical operation data, and the operation standby partition is realized through comprehensive analysis of the difference and similarity of the time-of-use electricity price vectors.
