enhance in execute_pscad

[PanMENdus]

Hey,

In my opinion certification conditions needs one more thing:

if cert.meets([('EMTDC Instances', volley)]) and (cert.available() > 0):
print('Acquiring Certificate Now! : %s', str(cert))
[...]

In my case - without 2nd condition it will pick 1st certificate that doesnt have any free licenses left. Sorry for not making a pull request but havent do it for a long time and got no time to prepare my IDE for it.

Additionally, not always embedded runs are possible because of permissions. PSCAD refers to C drive and program files path. It can be easly check by sys and site modules:

import sys
print(sys.executable)
import site
print(site.getsitepackages())

Sometimes users cannot install modules in python located in c/program files and need to install it outside of program files folder. Due to it embedded PSCAD python can not see site-packages folder. Same for external calls for PowerFactory user need to add a system path. It allows import modules and run scripts via embedded python. The code i added in execute_pscad.py (ofc path need to be adjusted e.g. in config.ini as a optional parameter):

try:
    sys.path.append(
        r"C:\Users\USER\AppData\Roaming\Python\Python37\lib\site-packages" #can be different path, i just tried to do it via appdata
    )
except:
    print("You are not correct USER, change appended path if needed")

Dear PanMENdus,

Thanks for this suggestion to add " and (cert.available() > 0)" to the certification conditions.

I have changed the code as such.

For your second suggestion, however, I am not so fond of changing the code.

In the Wiki it states:

4. Depending on the permissions, one may need to execute the following command to install the requirements in the user's "Roaming" folder, e.g.

python -m pip install --target C:\Users\<USERNAME>\AppData\Roaming\Python\Python37\site-packages -r requirements.txt

and

4. The MTB usually is able to find the Python path, but it can also be manually added to config.ini if required so that it points to the python 3.7.2 installations site-packages folder, e.g. C:\Program Files\Python37\Lib\site-packages or C:\Users\<USERNAME>\AppData\Roaming\Python\Python37\site-packages

Kind regards,

Peter
