Re: [TRNSYS-users] Very Simple IV Curve

[David BRADLEY <d.bradley@tess-inc.com>]

Alexander,
  There is an example that shows how to obtain an IV curve if you have not already found it. It is located in..\Trnsys17\Examples\Photovoltaics\IVcurve.tpf. The trick to the example, I think, is that the simulation time is used as a proxy for the load voltage.  I am not entirely surprised that you are seeing some odd behavior near the open circuit voltage and short circuit voltage points as the mathematics of the PV model become very difficult to solve at those points.
Kind regards,
 David

Hello to all,

I am new to TRNSYS and am currently trying to obtain very simple IV curves for one value of irradiation (70W/m2).

I have obtained experimental results by varying the resistance across a panel using a decade box, and would like to imitate my results on TRNSYS for validation.

I have tried to manipulate the simple IV curve example, however I obtain an IV curve which zigzags around the short circuit current and apparently has an infitinite open circuit voltage.

 

Any help is truly appreciated, and sorry if this is a very simple request.
