Hi, there
As I mentioned in previous Q/A, I simulate a project at Fort McMurray location where from November to February the solar irradiance is not strong enough to run the solar plant. Therefore, I would like specify this no operation period in SAM. One way as you suggest to specify system availability loss = 25% to account for the no operation period. However, this will derate the design production and capacity factor significantly as SAM consider the loss over the yearly basis. I tried to specify the specific no operation period using custom period function like this:
However, SAM generate errors when I try to run it with this customized availability loss periods. See below:
Please help to guide what else input I need to make it run. Besides, during the non-operation period, the plant will be moth-balled. So the heat loss and utility consumption should be considered separately - Let SAM simulate the operation on 8 month period for normal operation economics. Is there a way to do this?
Thanks,
Harry
