Example for the PVSimple model with constant load
Information
This model illustrates the use of the photovoltaic model.
The total solar irradiation is computed based
on a weather data file.
The PV is connected to a circuit that has a constant voltage
source and a resistance.
This voltage source may be a DC grid to which the
circuit is connected.
The power sensor shows how much electrical power is consumed or fed into the voltage source.
In actual systems, the voltage source may be an AC/DC converter.

Example for the PVSimpleOriented model with constant load
Information
This model illustrates the use of the photovoltaic model.
The total solar irradiation is computed internally by the PV
model through a connection to the weather bus.
The PV is connected to a circuit that has a constant voltage
source and a resistance.
This voltage source may be a DC grid to which the
circuit is connected.
The power sensor shows how much electrical power is consumed or fed into the voltage source.
In actual systems, the voltage source may be an AC/DC converter.

Example for the WindTurbine model
Information
This model illustrates the use of the wind turbine model which is connected to a DC voltage source and a resistance.
This voltage source may be a DC 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.
