This example illustrates how to use PV panel models
Information
This example shows how to use a simple PV model without orientation
as well as a PV model with orientation. The power produced by the PV is
partially consumed by the load, and the remaining part is fed into
the grid.
The PV produces different amounts of power on each phase according to the fractions
specified by the vector areaFraction={0.5,0.3,0.2}. In this example, 50%
of the power generation is on phase 1, 30% on phase 2 and 20% on phase 3.

This example illustrates how to use PV panel models with neutral cable
Information
This example shows how to use a simple PV model with neutral cable connection and without orientation
as well as a PV model with orientation. The power produced by the PV is
partially consumed by the load, and the remaining part is fed into
the grid.
The PV produces different amounts of power on each phase according to the fractions
specified by the vector areaFraction={0.4,0.0,0.6}. In this example, 40%
of the power generation is on phase 1, 0% on phase 2 (disconnected) and 60% on phase 3.

Example for the WindTurbine AC model
Information
This model illustrates the use of the wind turbine model,
which is connected to a AC voltage source and a resistive load.
This voltage source can represent the grid to which the
circuit is connected.
Wind data for San Francisco, CA, are used.
The turbine cut-in wind speed is 3.5 m/s,
and hence it is off in the first day when the wind speed is low.
The wind turbines produce different amounts of power on each phase according to the fractions
specified by the vector scaleFraction={0.5,0.25,0.25}. In this example, 50%
of the power generation is on phase 1, 30% on phase 2 and 20% on phase 3.
As expected the phase with the higher power production has the higher voltage deviation
from the nominal condition.
