Based on our practice in China on modeling load from field measurements, this paper systematically develops a measurement-based composite load model. Principles guiding the load modeling practice are discussed based on detailed analysis on stochastic characteristics of the modeling procedure. The structure of the measurement-based composite load model is presented. A multicurve identification technique is described to derive parameters. The generalization capability of this built load model is also investigated in this paper. Two cases are studied to illustrate the accuracy of the developed load model on describing the load dynamic characteristics in the actual power system.Keywords: Electric loads; Electric power measurement; Mathematical models; Stochastic control systems; System stability; Load modeling; Power system stability; Stochastic characteristics; Electric power systems Load modeling; Measurement approach; Power system stability200610.1109/TPWRS.2006.8731302015-12-07
