Abstract:
Currently the total power of PV-generators in the built environment
is small compared to the power of the distribution transformer. With
the steady growth of PV installations, the penetration of PV-generators
in the built environment will grow as well. This will lead to new phenomena,
which may eventually result in grid instabilities. Whether or not these
phenomena will occur depend on the high frequency parameters of the
inverter(s), the load and the utility grid. This paper describes a way
to model the harmonics behaviour in a utility grid. Next a simple test
method is presented that can be used to measure the high frequency parameters
of the loads and the inverters accurately.
