1. A load power device comprising:

  • a power input;

    at least one power output for at least one load;

    a plurality of sensors structured to sense voltage and current at said at least one power output; and

    a processor structured to provide real-time execution of;

    (a) a plurality of load identification algorithms, and (b) event detection and operating mode detection for the at least one load;

    wherein the load identification algorithms include a mode identification algorithm and a plurality of load classification algorithms for the at least one load,wherein the load classification algorithms include a first level identification function structured to read a cycle data buffer of the sensed voltage and current, extract voltage-current features, and output a first level identification and a corresponding confidence level for the at least one load,wherein the load classification algorithms further include a second level identification function structured to input the first level identification, an event sequence and a power event sequence, extract finite state machine features, and output a second level identification and a corresponding confidence level for the at least one load,wherein the load classification algorithms further include a third level identification function structured to input the second level identification and operating pattern information, and output a load device identification for the at least one load, andwherein said processor further includes a load use sequence function structured to input the first level identification, the second level identification, the load device identification, and a control action which controls the corresponding one of said at least one power output, and to create or update a load use database.
