Updated Tutorial - Example 4 (OpenIPSL#351)
* Copy SMIB_Tutorial repo contents to Resources folder Files from the external repository https://github.com/ALSETLab/SMIB_Tutorial have been copied to the Resources folder. This will allow us to manage the scripts to create power flow records directly within the OpenIPSL repository. * Update names inside create_pf_records module The following changes have been applied to create_pf_records.py: - Modelica object names have been updated to be upperCamelCase. - Replace variable 'V' with variable 'v' in Bus records. * Update regex expression in generate_component_list A new more explicit way of finding generators in the Modelica Network model has been introduced. A for loop is now used to iterate over several regex patterns to detect generator objects. * Update names inside gridcal2rec module The following changes have been applied to gridcal2rec.py: - Modelica object names have been updated to be upperCamelCase. - Variable 'V' has been replaced with variable 'v' in Bus records. * Update link inside main Instructions documentation Link to python scripts to create and populate records with PF results has been updated. The scripts are now available within the OpenIPSL repository. * Update steps defined in PFRecordCreation documentation * Update steps defined in InstallingGridCal doc Steps have been updated to ensure a working installation of GridCal 4.5.1 under a conda environment. * Fix HTML issue with li tags * Update steps defined in PopulatingRecords doc * Revert changes to tutorial 4 images * Update GridCal installation instructions - Instructions have been updated to install the latest version of GridCal. - Miniconda is no longer used. - GridCal installation is recommended on a python 3.12.7 virtual env. * Fix HTML issue with li tags * Clean up pf record generation utils - All python files are now located in the pf2rec folder below Resources/pf2rec. - Modelica, csv and PSS/E files have been removed from Resources. * Update python pf record creation scripts - Logic associated to OpenIPSL old versions has been removed to keep code simpler. - A list of regex patterns is used to identify generating units in OpenIPSL network models. * Update python pf record population scripts - Code has been updated to reflect changes in GridCal API and data model (reference version = GridCal v5.1.52). - Support for old versions of OpenIPSL has been removed to make the code simpler. * Fix invalid escape sequence issue in regex * Fix issue in transformer pf record generation Tail of the pf record was missing, leading to syntax errors. * Update PFRecordCreation doc - python scripts The instructions have been updated to properly use the pf record generation scripts. * Correct the unit * Update PopulatingRecords doc - PSSE Files PSS/E Files folder is no longer kept within the Resources folder. The instruction have been modified to guide the user in the process of creating the raw file that is used as an input to populate the pf records with GridCal. * Escape \ chars inside paths in documentation * Whitespace fix. * Fix case of Python --------- Co-authored-by: Dietmar Winkler <dietmar.winkler@dwe.no>

<h5>Creating and Integrating the Power Flow Structure</h5>
6+
<p>After completing the instructions in <a href=\"modelica://OpenIPSL.Examples.Tutorial.Example_4.Instructions.SMIBSystemAssembly\">Assembling a SMIB System</a>, you should have a <font color=\"blue\"><code>SMIB</code></font> folder inside your working directory. </p>
67
<ol>
7-
<li>Create a directory called <font color=\"blue\"><code>models</code></font> above your model current folder. </li>
8-
<li>Move your model folder to the directory created in <strong>step 2</strong>. For example, let&apos;s assume you are using the new version of OpenIPSL, then if your model is saved in a folder called <font color=\"blue\"><code>SMIB</code></font>, the new path of your folder should be <font color=\"blue\"><code>models/SMIB</code></font>. </li>
9-
<li>Make sure the directory <font color=\"blue\"><code>pf2rec</code></font> downloaded from the <font color=\"blue\"><code>SMIB_Tutorial</code></font> repository is in the same directory. The tree below shows how your folder structure should look like:
8+
<li>Create a directory called <font color=\"blue\"><code>SMIB_Example</code></font> at the same level where the <font color=\"blue\"><code>SMIB</code></font> folder is located. </li>
9+
<li>Create a directory called <font color=\"blue\"><code>models</code></font> below your new <font color=\"blue\"><code>SMIB_Example</code></font> folder. </li>
10+
<li>Move the <font color=\"blue\"><code>SMIB</code></font> folder below the previously added <font color=\"blue\"><code>models</code></font> folder. </li>

<li>Copy the <font color=\"blue\"><code>pf2rec</code></font> folder from <a href=\"modelica://OpenIPSL/Resources/utils\">Resources</a> to the <font color=\"blue\"><code>SMIB_Example</code></font> folder. </li>
12+
<li>Move the <font color=\"blue\"><code>create_records.py</code></font> and <font color=\"blue\"><code>run_pf.py</code></font> Python files one level up (i.e., to the <font color=\"blue\"><code>SMIB_Example</code></font> folder). The tree below shows how your folder structure should look like:

<h5>Populating Power Flows with GridCal</h5>

<li>In the diagram layer of your SMIB model, double click the power flow component <font color=\"blue\"><code>pf</code></font>. Select the newly created power flow <font color=\"blue\"><code>PF00000</code></font> as the value for the <font color=\"blue\"><code>PowerFlow</code></font> field. By doing so, we are specifying that the model will initialize using the power flow results in that specific container.
