Respected Ray, can you explain the profile values in example code "ex_wind_profile", How are they defined? The valves are defined as given below. I think 0.72 is 75 % output of wind generators but what does 1.18 indicate? but the results are contradicting with this idea therefore let me know the concept behind it.
windprofile.values (:, :, 1) = [ 0.72 0.80 0.88; 0.49 0.65 0.81; 0.36 0.60 0.84; 0.50 0.82 1.14; 0.60 1.00 1.40; 0.22 0.70 1.18; 0.00 0.50 1.00; 0.33 0.85 1.37; 0.46 1.00 1.54; 0.54 1.10 1.66; 0.48 1.06 1.64; 0.35 0.95 1.55; ________________________________ From: [email protected] <[email protected]> on behalf of Ray Daniel Zimmerman <[email protected]> Sent: Thursday, 15 July 2021 1:37 AM To: MATPOWER-L <[email protected]> Subject: Re: How to load Pd in a loadprofile ,when load buses are approximately 30 . According to the error message, it seems that the dimensions of your profile.values is not consistent with the dimensions of your transition probability matrices. The 2nd dimension of profiles is 3 (i.e for 3 scenarios), but the transition probability matrices appear to be defined for a single scenario. As far as plotting, there are a few plotting functions that are general and documented (e.g. plot_uc(), plot_gen(), plot_storage()), but the functions used in the test files for plotting are specific to those cases. You would probably need to modify them to work for your own cases. Ray On Jul 14, 2021, at 7:29 AM, MALIHA SHAH <[email protected]<mailto:[email protected]>> wrote: Respected Zimmermen! How can I resolve bellow error. As I have built a code from stochastic DC OPF model ex 4, for multiple periods. where I used command: t_most_suc_new(0, 1, 1, ' location name'). This is for secure stochastic uc model ploting. But i edited this function according to my file. Still I am not confirm if we want to generate graph we have to built complete function ? How can we learn about graph and plots in Matpower and Most. Error: Error using loadmd (line 399) loadmd: scenarios dimension of profiles(1).values (3) must be 1 or nj_max = 1 Highly thankful for your suggestions.

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 On Jul 7, 2021, at 3:56 PM, MALIHA SHAH <[email protected]<mailto:[email protected]>> wrote: 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.

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>.

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.
