The following two models are included in the package:

• PVarray_Grid_IncCondReg_det.mdl is a detailed model of a 100-kW array connected to a 25-kV grid via a DC-DC boost converter and a three-phase three-level Voltage Source Converter (VSC). Maximum Power Point Tracking (MPPT) is implemented in the boost converter by means of a Simulink model using the “Incremental Conductance + Integral Regulator” technique.

• PVarray_Grid_PandO_avg.mdl is an average model of a 200-kW array connected to a 25-kV grid via two DC-DC boost converters and a single three-phase VSC. The MPPT controller based on the “Perturb and Observe” technique is implemented by means of a MATLAB Function block that generates embeddable C code.

A Help file containing useful information on the two models is also included.

Version Published Release Notes
1.2.0.0

The two PV array models (detailed and average) have been updated.
Diode characteristic inside the PV Array blocks is now correctly implemented as Id=Isat*[exp(Vd/Vt)-1].
Thanks to Subesh and Buvana for raising this problem.
