[TRNSYS-users] PV panel with PCM

[David BRADLEY]

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
