Mehdi,
Have you tried first opening the provided IVF solution?
Trnsys17\Compilers\IvfCXE2011\IvfCXE2011.sln
You can simply drop and drag your fortran *.f90 file under the “MyType” section to create and compile an external DLL to run your component in TRNSYS. There
might be more info towards the end of the programmers guide.
Regards,
Matt

Subject: Re: [TRNSYS-users] Load Splitter for supplying power to electrical load and electrolyser for H2 generatoin
Hello everyone,
I am new user. I am trying to start my own simulation, I need first to create my own component. I am using Microsoft visual studio (Intel visual Fortran).
But, I have faced a problem creating new component! After creating proforma, I try to export as Fortran and save it, the Microsoft visual studio will open and
a small window appears and says:
‘’ The Project …… must be converted to the current visual C++ format. After it has been converted, you will not be able to edit this project in previous versions
of visual studio. Convert and open this project? ‘’
Does anyone knows what is the problem and how can I solve it?
Best regards
Mehdi Taebnia
Tilak,
If the comparisons are simple then you may be able to use equations in the input file to determine how much power needs to go to meet the load or run the electrolyzer. If they get more complex then there are some master controller components available in
the Hydrogen Systems directory (look first at Type105). Bear in mind that these are quite generic controllers. In all of the cases that I have had to deal with, I needed to write my own controller model using a Fortran compiler because there were some special
requirements on the controls (for example what do you do if the load cannot be met by PV and the state of charge in the hydrogen tank is so low that you cannot run the fuel cell either.
Also as a side note, keep in mind that electrolyzers have a fairly significant standby power requirement. This would be some power that they draw when idle so that when excess electricity becomes available, the hydrogen produced is pure enough to be useful.
There are also systems in which the electrolyzer is shut down (instead of allowed to idle) but in these cases the hydrogen that they produce while being started up is not useful. This is another reason why you might need to write your own master controller
component.
Kind regards,
David

Hi David,
I am currently doing a Miner Thesis project as part of my Master course. I am designing a Solar PV-Thermal and Hydrogen system for heat and power. I am looking for a LOAD SPLITTER which should perform the following
1. First compare the PV power and the load demand at that particular hour.
2. If the load is less than or equal to PV power generated, than the supply the power to Load only.
3. If there is excess power from the PV, supply to electrolizer to generate hydrogen.
4. Hydrogen will be utilize when there is no solar radiation.
I would highly appreciate if you could provide me your guidance in the above area mentioned,
Looking forward to your kind response.
Tilak
