Hasan,<br>
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
(<a class="moz-txt-link-freetext" href="http://trnsys.com/tess-libraries/individual-components.php">http://trnsys.com/tess-libraries/individual-components.php</a>). <br>
<br>
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.<br>

kind regards,<br>

<div>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. </div>
