Abstract
The paper concerns the representation of distributed loads of mixed but known composition. A general load model is employed which relates relative changes in active-and reactive-load demand to relative changes in applied voltage and frequency in terms of a set of four characteristic parameters. The object is to identify analytically the resultant characteristic parameters at a principal load busbar, taking into account the effects of feeders and distribution transformers as well as load composition. The analysis may start at any network level where load characteristics are known. An example is given, illustrating the application of the method.Keywords
