Hello!
First of all, thank you for providing us with such a great tool.
We are trying to simulate a PV - Battery system for an ice cream factory. The PV data have already been generated with another software, therefore I am using a Generic system here. I have a few questions which I appreciate if you could answer:
1- The financial aspects are not important for us, on the other hand, for modeling a battery in SAM you have to choose a financial model! So which model do you suggest to go with and what should the settings be?
2- When there is no Grid limit, there is no energy loss, but a huge amount of energy is exported to the grid from system. When I set the grid limit to 0, we have high energy loss but there is no export to the grid, and also the annual energy is almost halved. So the question is how to reach an optimized situation? (Is increasing the limit with small increments and then simulate for each, one by one a good idea?). Why does even the energy get lost when it is not exported to the grid?
The goal of the owner is
complete Autarky. So, to summarize, I want to know what the
best configuration is to reach the:
- Minimized energy loss
- Minimized energy to grid from system (would be great if we didn't have this one at all!)
- Minimized energy to load from grid
at the same time. I have attached the SAM file with a few variations. The battery is provided by the owner, a 4.15 MWh (max. capacity) with a bank power of 400 kW (peak load). (Increasing the battery capacity also doesn't have much affect on reducing the energy to load from grid). Also, I appreciate it if you could give me a few hints on which datas are actually useful for us to present to the owner and justify our argument, there are a lot of variables which are a bit confusing!
Thank you so much for your help and time already!
Sincerely,
Keyhan
