# PowerFactory Scripter on tool.adjiebrotots.com

PowerFactory Scripter is a free calculator that runs in the user's browser. This skill turns the user's question into **one link** that opens the tool on their scenario. The tool, not you, works out the result: its figures come from its own model and data, and anything you work out separately can differ from what the user then sees.

## What it decides

- **PowerFactory Workflow Builder** (`powerfactory-scripter/builder`): Which study the PowerFactory Python script runs, and in what order: a workflow of blocks (load flow, N-1 contingencies, short circuit, RMS or EMT simulation, checks, loops, results tables and graphs), the project and study case it opens and where its results go. The tool writes one ready-to-run script for DIgSILENT PowerFactory 2024 from that workflow, and the user downloads it. It does not run PowerFactory or work out a study result. The script comes from the tool, so a link to it gives the user the whole script.
- **PowerFactory Scripter: Legacy Form** (`powerfactory-scripter/legacy`): Which kind of PowerFactory study a Python script runs: a sweep of input values, an optimisation, a run of scenarios from a file, or an outage screening (N-1 or N-2), in which study type (load flow, RMS, EMT or harmonic) and with what options. The tool writes one ready-to-run script from the form, and the user downloads it. It does not run PowerFactory or work out a study result. The script comes from the tool, so a link to it gives the user the whole script.

## Workflow

1. **Pick the page.** Read the user's request and choose the page above that answers it. Open its reference (`references/<page>.md`, listed under Files) and read the LINK FORMAT, the most important keys and the Quick Starts. The reference is long: read the parts you need.
2. **Separate what the user said from what you must choose.** Every figure the user gave goes in as they gave it (convert units or periods only to match the field, and say so).
3. **Fill every other input that matters with a researched assumption.**
   - If you can search the web, do it for figures that change over time or by place. For this tool that usually means the PowerFactory object and variable names, the study standard (IEC 60909, the grid code's fault ride-through curve), and the user's project and study case names as they gave them. Prefer official and primary sources and note each source and its date.
   - If you cannot search, use your own knowledge and say it is an estimate as of your knowledge date.
   - Start from the nearest Quick Start (`qs`) for the user's place and case, and keep its figures unless you have a better one for this user. Send only what differs from it.
   - Prefer what the user said earlier in the conversation over general figures. Never invent a figure the user gave differently.
4. **Build the link with the script** (it checks every key, range and choice, and encodes the link exactly):
   ```bash
   python3 scripts/build_link.py --fields powerfactory-scripter/builder --find <words>     # look up keys
   python3 scripts/build_link.py --quickstarts powerfactory-scripter/builder --find <words> # look up Quick Starts
   python3 scripts/build_link.py spec.json                                   # build the link
   ```
   `spec.json` holds `page`, `qs`, `set` (key: value, in the units the field shows on screen, numbers written plainly: `800000`, `6.5`, never `800,000` or `6,5`), `why` (key: your reason, 200 characters at most, shown to the user beside the value; a list key or `json` can have one too), `note` (one line, such as the place and date), `json` (an object, for a page whose reference defines it). If it prints NOT BUILT, fix what it lists and run it again. Use the link it prints exactly as printed.
   The script checks every form field: its key, range, step and choices. List keys, part settings (`blk....`, `graph....`) and `json` are checked by the tool when the link opens, so write them exactly in the syntax the reference gives (its COMPACT LISTS, REFERENCE and JSON sections), with the names it lists. A Quick Start sets only what its line in the reference lists; when a list key (a set of tickers, portfolios or offers) replaces what the Quick Start holds, send every setting you want with it.
   If you cannot run code, build the link by hand from the LINK FORMAT in the reference, using only keys and values listed there, and check each value against its range.
5. **Reply in the format below, and stop.** Never write the PowerFactory Python script yourself, not even part of it: the tool writes it from the link, and the user downloads it there.

## Reply format

Your whole reply has these four parts, in this order, written in the user's language (keys and the link stay as they are):

1. **Your inputs**: a short list of what the user stated, each with the value that goes in the link.
2. **Assumptions**: a numbered list (or a table: Input | Value | Source or rationale), one entry per input you chose, each with its value and its source with the date for anything you looked up, or "estimate" and your reason for anything from your own knowledge. Put the same reason, shortened, in that key's `why`.
3. **The link**, as a clickable Markdown link to tool.adjiebrotots.com/powerfactory-scripter/..., and again inside a code block so the user can copy it if their chat app breaks a long link.
4. The sentence: **Open the link to see the result.** You may add one line inviting the user to correct any assumption, and then you will send a new link.

**Do not state results.** No verdict, figure, estimate, range, "roughly", "likely", or preview of what the tool will show, not even if the user asks. The only numbers in your reply are the inputs in the link. If the user asks what the answer is, explain that the tool works it out from these inputs and the link opens it, and offer to change any input.

If the request is outside what this tool does, say so, give the tool's address and help the user as you normally would.

## Link format (summary)

```
https://tool.adjiebrotots.com/powerfactory-scripter/builder/#load&v=1&qs=<quick start>&<key>=<value>&why.<key>=<reason>&note=<one line>
```
- `#load` then `key=value` pairs joined by `&`, each value percent-encoded. `v=1` always.
- Values in the units the field shows: `6.1` for 6.1 %, `800000` for 800,000. A choice takes its listed value.
- The tool starts from the Quick Start (or its defaults) and applies each key. Keys not named keep their base value.
- Out of range numbers are pulled into range and unknown keys are skipped, and the tool tells the user. The script stops you before either happens.
- Never use the keys `s`, `open` or `embed`.

## Worked example

**User:** using tool.adjiebrotots.com/powerfactory-scripter/builder, write me a PowerFactory script for the Nine-bus System project that runs an N-1 screening on the lines only and saves the results tables as Excel files

**Spec** (`powerfactory-scripter/builder`):

```json
{
  "page": "powerfactory-scripter/builder",
  "set": {
    "blk.n1.project": "Nine-bus System",
    "blk.n5.trafos": "false",
    "blk.n1.tableFmt": "xlsx"
  },
  "why": {
    "blk.n1.project": "The project the user named, as they wrote it",
    "blk.n5.trafos": "The user wants lines only, so transformers are not taken out",
    "blk.n1.tableFmt": "The user wants the results as Excel files"
  },
  "qs": "n-1",
  "note": "N-1 screening of the lines, Nine-bus System, Excel tables"
}
```

**Reply:**

**Your inputs**

- blk.n1.project: Nine-bus System

**Assumptions**

1. Study: the N-1 screening Quick Start (qs=n-1): a base load flow, then each outage in turn with a load flow after it, and a results table of the highest line loading and lowest busbar voltage.
2. Outages: lines only, so the transformers are not taken out (blk.n5.trafos).
3. Project: Nine-bus System, exactly as the user wrote it.
4. Tables: saved as Excel files rather than CSV (blk.n1.tableFmt).
5. Study case, output folder and the rest of the Start block: left as the Quick Start has them, so the script uses the project's active study case and writes next to itself.
