Grid-Connected PV Array

Two demonstrations of a grid-connected PV array using Simscape Electrical.

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.
