This paper describes the estimation of the electric load composition on a consumer side of a distributed power system. That is to say, the purpose of estimation is to determine the amount of each load class with respect to the total electric current waveform from instrument reading. To carry out this work, the reduced multivariate-polynomial model is applied when the distributed power system has the electric loads supplied from the different voltage level through a nonideal transformer. The estimation problem in this paper is also considered with relation to the power-quality issue.
