Power consumption analyzing server and power consumption analyzing method thereof

A power consumption analyzing method for a power consumption analyzing server, the power consumption analyzing server comprising a processor, a network interface and a storage, the storage being configured to store a user database that records a user datum of each of a plurality of users, the power consumption analyzing method being executed by the processor and comprising the following steps:

• (a) clustering the users into a plurality of groups according to the user data;
• (b) for each of the groups, generating M+1 encoded outputs by inputting a total power consumption time sequence datum of a reference user corresponding to the group among the user data into an autoencoder, where M is a positive integer;
• (c) for each of the groups, receiving an actual appliance measurement datum from an energy management system apparatus of the reference user in the group by connecting to the energy management system apparatus via the network interface, the actual appliance measurement datum being associated with M categories of appliances;
• (d) for each of the groups, labeling M encoded outputs among the M+1 encoded outputs according to the actual appliance measurement datum to map the M encoded outputs to the M categories of appliances;
• and
• (e) for each of the groups, establishing a non-intrusive load monitoring system (NILM) model of the group according to the M+1 encoded outputs and the actual appliance measurement datum after the M encoded outputs are labeled.
