Turbine output control

Hi Mohammed,

The csvread() function reads data from the CSV file as a 2-D array. In your case, you can use a script like the following to read data from the array:

If you want csvread() to read the data as a single array, you could modify your CSV file to store the data as a row of comma-separated values instead of a column of values. For example if the file test.csv contains the following:

Then you could use the following script to read the file:

The LK sample script csv-functions.lk has some other examples: github.com/NREL/SAM/tree/develop/samples/LK%20Scripts%20for%20SAM

Dear Mr. Gilman,

My true apologies for this being a never ending quest, but there is still something wrong..

When I try what you suggested lastly, i.e. all the array values separated by a comma and placed in the first cell of the CSV file forming a row of comma separated values, LK only reads the first value of 0 ..

Further, I tried to separate the values by a comma using (text to columns - delimited - comma) function from the Data tap in Excel, however, it gives the following (seems like an array placed at the first index of the main array):
AEG  =  [ [ 0, 284000000, 284000000, 284000000, 284000000, 284000000, 284000000, 284000000, 284000000, 284000000, 284000000, 284000000, 284000000, 284000000, 284000000, 284000000, 284000000, 284000000, 284000000, 284000000, 284000000, 284000000, 284000000, 284000000, 284000000, 284000000 ] ]

and of course the same error message appears:  
access violation: expected numeric, but found array

Please have a super quick look on my CSV file and the very simple code:

path = 'C:/Users/Mohammed/Desktop/LCOE Calculation' + '/';

AEG = csvread (path + 'AEG.csv', {'numeric' = true, 'table' = false});
variable_costs = csvread (path + 'variable M&O costs.csv', {'numeric' = true, 'table' = false});  

for  (i = 0 ; i<26; i++)

{
OM_production_capacity_expenses = variable_costs * AEG;  

         simulate ();         }
   
   outln(OM_production_capacity_expenses);      


of course when  I set i= 26, this code gives error array index out of bound, while when I reset it to i=1, it goes back to error of access violation: expected numeric, but found array..

Thanks for your efforts and time.

Regards,
Mohammed 


         

Hi Mohammed,

In your code, the variables AEG and variable_costs are two-dimensional arrays, each with one row of data. To read the values in the array, you must provide two array indexes in brackets. Your loop should look like this:
