Modelica definition
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.

This example illustrates how using a variable power source
Information
This example shows how to use a variable generator model. The generator model has to be used
together with a voltage source generator, which is in this example the
grid model.

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.
