Analysis of Inverter clipping for different PV panel String

A Simulink model is developed to simulate & approximate the effect of inverter clipping on daily yield production (KWh or units).

This model is developed to simulate the effect of clipping on daily yield production (KWh or units).For this purpose we have compared two different string configurations of panels for 20Kw system each. One configuration is setup to demonstrate the clipping mode of inverter, and the other will simulate in a regular manner. Comparison of both the daily yield production will determine the dominancy of one configuration over the other. The method used for finding the daily production is by calculating the area under the curve (AUC) method.

The configuration of string connected panel is stated below. Each of the config will generate 20Kw of power.

Configuration 1 (clipping)

 14Kw string config

 6Kw string config

Configuration 2 (non-clipping)

 10Kw string config

 10Kw string config

Irradiation and Temprature data can be acessed from CSV file in the form of vector.Have to define the row and colom location of data in CSV.

All the instructions to use the model and code are stated in pdf report.
