Re: [TRNSYS-users] Without grid simulation

Tri,

  There are a number of different ways that you can do this. The method will depend on which battery and battery controller models are being used and even more specifically which modes of the battery and battery charge controller you are using. In general, look for ways of setting up the controller so that it does not go into a "charge battery from grid" mode. Then you can interpret the "grid power needed" output instead as a "load unmet" condition.

kind regards,

 David

Dear All,

I want to make simulation of pv system to supply electricity for specific demand. The thing is, i don't want to use grid as complement of pv system. So I can predict when the electricity shortage will occur, how long, etc.

I have tried to make it in trnsys, but it is automatically powered by grid when the power from pv and battery is not sufficient. So, I made new simple component to turn off the system when the power generation is not enough.

Is there any way to turn off the power from grid without making new component?
If so, can it be explained in detail?which type should I use?


Thank you,

Tri Ayodha Ajiwiguna
