Dear Paul;
How SAM biomass model calculates LHV of Biomass feedstock?
Thanks in advance

Bug in Plant Specs Biomass Combustion Model

Hello.

There must be a problem with the option "Enable time of dispatch schedule" in the Plant Spec of the biomass combustion model.

If I introduce more than 1% (0,1) in the fractional generation capacity input I receive the following message:

exec fail (biopower): fractional generation capacity exceeds boiler design for period2
Simulation biomass failed
SSC requries input "gen", but was not foung in the SAM UI or from previous
Simulation singleower failed.!

Attached is the 2017 SAM file I am using as example.

Minimum feedstock to run

I am trying to calculate the energy output from a biomass power plant. I changed a few parameters for the input data but there seems to be something wrong since the simulation results doesn't give any details on the energy output and a lot of the other parameters. What should I consider changing. Attached is a copy of the simulation results.
Thank you.

Biomass Transportation Cost

Hi,

I was wondering where I should enter the transportation and harvest cost for biomass in SAM. If I divide these costs by total capacity, I would get cost per kW. Are these costs part of the variable operating costs? And, if yes, how can I convert this kW number to kWh?

Thanks

Nominal or Real LCOE

Dear Paul;

Thank you for very useful replies. However, I have some questions?

1- Which prefer to use Nominal or Real LCOE in biomass model. the analysis period 20 years?. However the inflation rate in Egypt is 8%

2- How SAM computes Gross annual energy in biomass model?

LCOE calculator

Dear,
when I run My LCOE calculator model of biomass the value of the outputs in metrice is NAN.
I don't know why?

Please, answer me.

Metric Value
Annual energy (year 1) NaN
Annual biomass usage (year 1) 93,000 dry tons/yr
Capacity factor (year 1) NaN
Levelized cost of energy NaN

inflation rate

Dears:
I would like to ask, Is there a limit of the value of inflation rate in the input page?.
I have created a model of biomass power plant. but when I set inflation rate to 8% the model cannot detect the IRR.

Thanks in advance

Cannot open SAM on OS X El Capitan

Hello, I have downloaded SAM onto my Mac which has El Capitan. When I double click to open, I get a "There is no application set to open the document" message whether I try to open from the HD, applications or download. Please advise and thanks.

Feature request: System design - inverter types and their string sizes

Feature request: System design - inverter types and their string sizes
Can the following be considered for each subarray?
1) different inverters
2) different string lengths

Also can the following be considered
1) Increased number of sub-arrays
2) flexible application of string lengths to multiple input (MPPT) invterters.

Thanks for a great product
Mark
