Buildings.Electrical.AC.OnePhase.Sources.Examples.PVPanels

Information

This example shows how to use a simple PV model without orientation as well a PV model with orientation. The power produced by the PV is partially consumed by the load while the remaining part is fed into the grid.

Buildings.Electrical.AC.OnePhase.Sources.Examples.WindTurbine

Information

This model illustrates the use of the wind turbine model which is connected to a AC voltage source and a resistance. 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.
