**trns.rar** - The model used for creating the reference voltage is shown
in Fig. 4. First, photovoltaic output current (Ipv) and output
voltage (Vpv) are passed through a first order low pass filter
with a magnitude of G = 1 and a time constant of T = 0.01
seconds in order to filter out the high frequency components
or harmonics from these signals as shown in Fig. 5 and Fig. 6.
The filtered current and voltage signals (Ipv_F and Vpv_F) are
then fed into the MPPT control block that uses the Incremental
Conductance Tracking Algorithm. An algorithm that is based
on the fact the slope of the PV array power curve shown in
Fig. 7 is zero at the Maximum Power Point (MPP), positive on
the left of the MPP, and negative on the right. The MPP can
thus be tracked by comparing the instantaneous conductance
(I/V) to the incremental conductance (∆ I/∆ V) [11] as in (1):

**Grid-Connected-PV-Array.zip** - Two demos illustrate use of SimPowerSystems for modeling a PV array connected to a utility grid.
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.

**lgfault.rar** - lgfault is both a directory and a function.
The program lgfault is designed for the single line-to-ground
fault analysis of a power system network. The program requires
the positive-, negative- and zero-sequence bus impedance matrices,
Zbus1 Zbus2,and Zbus0.The bus impedances matrices may be defined
by the user, obtained by the inversion of Ybus or it may be
determined either from the function Zbus = zbuild(zdata)
or the function Zbus = zbuildpi(linedata, gendata, yload).
The program prompts the user to enter the faulted bus number
and the fault impedance Zf. The prefault bus voltages are
defined by the reserved Vector V. The array V may be defined or
it is returned from the power flow programs lfgauss, lfnewton,
decouple or perturb. If V does not exist the prefault bus voltages
are automatically set to 1.0 per unit. The program obtains the
total fault current, bus voltages and line currents during the fault.
