PowerFactory setup example outdated. #320

Description

The PowerFactory WECC example on the main branch is not updated with the latest MTB PowerFactory component. When running the script it raises an error.

The main issue is that the latest MTB component has a signal for available active power Pavail_sub, and in the setup example this does not appear. So the script raises an issue.

It will be very nice for the users to have an example setup that the user will simply need to change the path on the execute object and press execute to run all the cases. This will make it easier to understand the tool and also easier to collaborate on it.

This is the error on the output windows:
err - Traceback (most recent call last):

AssertionError

err - Python Script 'execute' stopped at error

Steps to reproduce

1. Load the Setup Example into PowerFactory
2. On the execute object (ComPython) in PowerFactory, naivgate to the Script tab and add the path.
3. Execute the PowerFactory object (ComPython)

Expected behavior

The MTB should be run as expected creating the study cases and variations.

Actual behavior

An error is raised.
