Normally, an electric grid is treated as an infinite source/sink
of power because the amount of power that is contributed by the PV
is negligible in comparison to the power of the grid. In small scale
applications, I would recommend that you use Type188 (AC bus bar).
The component is a very simple energy balance of power sources and
power loads and it assumes that the devices on the grid are all
voltage regulated. The actual voltage and frequency of the grid
doesn't really matter in this case because the size of the TRNSYS
time step is very large in comparison to the time constant of the
grid. TRNSYS time steps are on the order of 1 to 5 minutes so the AC
grid just looks like a steady state process.<br>
