Constant-impedance,
constant-current and constant-power ZIP models of electrical loads are commonly
used in smart grid and residential load applications. Some of residential loads
are of nonlinear nature such as LCD monitors and computers. In this study, first,
equivalent ZIP model formulas of parallel-connected electrical loads are
derived. Then, the ZIP models of an LCD monitor, a computer case and the
computer case and the monitor connected in parallel have been obtained using
experimental data and least-squares curve fitting method. Finally, the
equivalent ZIP model formulas are tested with the experimental data. It has
been found that for the rectifier nonlinear loads with different ZIP
parameters, the formulas do not give acceptable errors. Therefore, for
rectifier nonlinear loads, the measurement-based approach for load modeling
must be performed.
