Offshore BOS variables for statistical analysis

Hello, I have some question regarding offshore balance of system variables for statistical analysis as listed below.

1. Are offshore BOS variables not available for input to parametric/stochastic analysis?

2. most of offshore BOS variables shows non-relevance to tornado chart output such as levelized costs and total installed costs even with extreme change (up to 100%) of input variables, is this already known problem and any way to fix it?

Regards,
Seyong

windpower SSC module and input from memory

Hi there. I am trying to script with SAM SDK using the windpower module. I wish to make use of the wind_resource_data SSC input that allows the weather data to be input directly from memory as opposed to in an SRW file, but it does not mention the required data and their respective keys (as done with the PVWatts module).

Creating typical year file from long-term data for wind power performance analysis

Hello,
I am trying to create my own weather file in South Korea for input to SAM wind power performance modelling.
This link (https://sam.nrel.gov/weather) gives me an idea about typical year file but not enough detail to implement it for the wind case.
If I have long-term wind regime at project site in South Korea, say 20 years worth data, derived from MCP (measure-correlate-predict) method, which methods are available for me to determine typical values and derive a set of one year data?

Thanks,
Seyong

SAM Crashes Using Downloaded .srw Files

Hello,

I am in a renewable energy systems course at the University of Wisconsin and many, possibly all, of my classmates and I are having this same issue. Our assignment asked us to download 2012 NREL WIND toolkit data for a specific zip code (53597) and the data successfully saves to the computer. The file directory looks good and everything. However, once you hit "Simulate," SAM immediately crashes. This is an issue affecting both Macs and PCs.

I have attached my .sam file in case it helps troubleshoot this issue. Thanks for your help!

Best,

Erik

Converting Wind Toolkit Data to SRW

Hi,

I am trying to write a python script for wind, with a workflow similar to the solar example shown here:
https://nsrdb.nrel.gov/api-instructions

The workflow would be:
1. Download resource data for a desired lat/lon, using the NREL API
2. Simulate power output for a desired turbine type using the SCCAPI module

could not check hub height compared to resource height - Wind Turbine

Dear SAM Team

I am trying to simulate Wind using SAM version 2017.1.17 but I get the notification said "Could not check hub height compared to resource height. This may indicate a problem with your weather file".

I have changed my file to the Windows (CR/LF) or Unix (LF) format but I still face the error.
Here I attached my file (80m.srw). Please take a look.

My appreciate for some advices.

Best regards,
Soares

Hybrid System (Wind+PV)

How can we define and simulate Hybrid (Wind + PV) system ? Using wind and solar system together in a unit system can reduce the size of the battery or storage system. This reduce the cost of the project.

Wind weather data

Dear Sir/Mdm

I am trying to model wind farm in multiple locations in California, tried to download weather data through NREL and the latest available data was from 2011,Is there any sources that i can download multiple locations weather data (Latest)

Regards
Saman

Wind

Dear Paul

Do you know any resource (website or etc) which has California wind farms information such as Turbine, Lay out and size of the system?
for solar there is https://www.californiasolarstatistics.ca.gov/data_downloads something similar for wind.

Regards
saman
