1. A method of identifying electric load types of a plurality of different electric loads, said method comprising: providing a load feature database of a plurality of different electric load types, each of the different electric load types including a first load feature vector having at least four different load features; sensing a voltage signal and a current signal for each of said different electric loads; determining a second load feature vector comprising at least four different load features from said sensed voltage signal and said sensed current signal for a corresponding one of said different electric loads; identifying by a processor one of said different electric load types by determining a minimum distance of said second load feature vector to the first load feature vector of said different electric load types of said load feature database; employing i and k as indices; employing K as a count of records in said load feature database as indexed by k; employing δ as a constant value; employing D ik as distance between the second load feature vector and the first load feature vector and as the k th record in the load feature database; and determining probability of the corresponding one of said different electric loads being the i th one of the different electric load types of said load feature database from: Pm i = max ⁡ [ ( 1 δ + D ik ) k = 1 , … ⁢ , K ] .
