Re: [TRNSYS-users] PV panel with PCM



Hasan,
  Some years ago, we wrote a PV/PCM panel component that modeled a PV attached to a PCM substrate. We also have a model of a PCM wall material (for use usually with Type56 although it does not have to be) that could be pretty easily modified to account for energy addition from a resistive element embedded in it. My concern with such an approach would be that if the PV is directly connected to a resistive element that is embedded in the PCM it would be important to carefully characterize the current-voltage characteristic of the resistor since the intersection of the PV characteristic and the resistive load characteristic would determine the system's operating point. If you plan on having a maximum power point tracker on the PV then your system could be fairly easily modeled with a standard PV component (Type194) and a somewhat modified version of Type1270 (http://trnsys.com/tess-libraries/individual-components.php).

  Of course the above assumes that your PCM storage is fairly basic (a panel of PCM that can be characterized by a single temperature that does not change during transition). If your PCM is more a more complex geometry or a material that does change temperature through transition then please send me some details and I can try to comment.

kind regards,
 David

Hi Trnsys Users,

I am trying to model a building attached with a PV array which is coupled with PCM storage. Could you please advise me the approach I need to take in order to model this kind of a system and the needed trnsys components or help files relating to the same. 

thanks 

Hasan
