Embodiment Construction
[0061] The present invention will be further explained below in conjunction with specific embodiments and accompanying drawings.
[0062] see figure 1 , the present invention comprises the following steps:
[0063] 1) Establish a load characteristic database, which stores a variety of load characteristics of various household appliances: each appliance in the characteristic database stores a set of multidimensional data, mainly including the steady-state characteristics, transient characteristics and operating mode characteristics of the electrical appliances. kind;
[0064] 2) Use the load feature stored in the feature database as the original training set, and generate N training subsets from the original training set through Bagging sampling technology;
[0065] 3) Perform recursive analysis on each training subset to generate a decision tree: the generated decision tree is an inverted tree structure. The decision tree takes the training subset as the root node, adopts a...
