Unfortunately, setting up these profiles is a little more complex than I would
like.
First of all, setting rows to 0 will make the profile apply to every unit in
the final gen matrix, including non-wind generators and even dispatchable
loads. So that’s probably not what you want.
However, there is a subtlety in how rows is interpreted, depending on whether
you are calling the getprofiles() function with an idx argument or not. If not,
then rows refers to the row index in the final gen matrix, i.e. gen(rows, …).
If so, then rows is an index into the idx vector provided to getprofiles(), so
it applies to gen(idx(rows), …). This allows you to add wind generators using
add_wind() and then set up your profile with rows that address them
consecutively as 1, 2, 3 …
Hope this helps,
Ray

thankyou for the suggestion.
Another question is how to use wind profile provided in example code for more
than 1 generator. I changed the rows value from 1 to 0 in order to apply for
all but the results indicate as the other generators are off( profile does not
work for all generators). Secondly, from the discussion list I got an answer
explaining the row and values field of wind_profile function for 3 generators.
But it did not work. You can check the photos attached, showing the results and
the answer from discussion list which I tried in my code.
thanking you for your time.

Subject: Re: How to load Pd in a loadprofile ,when load buses are approximately
30 .
The example in
most/lib/t/ex_load_profile.m<https://matpower.org/docs/ref/matpower7.1/most/lib/t/ex_load_profile.html>
will apply to all loads, whether fixed (PD/QD columns of bus) or dispatchable
(negative gen). The profiles in MOST use the
apply_changes()<https://matpower.org/docs/ref/matpower7.1/lib/apply_changes.html>
function described in Section 9.3.5 of the User’s
Manual<https://matpower.org/docs/MATPOWER-manual-7.1.pdf>. See Table 9-4 for
the details of how to make your changes apply to only fixed, or only
dispatchable, etc.
Hope this helps,

Respected Ray,
How can I make a varying loadprofile, which contains 30 load buses
approximately. As in the example most , there was one load bus which was coded
negative generation . How can the Pd given in case 30 included in profiles in
order to run it smoothly like in the example.
Will be thankful.
