PowerFactory Automation

Natural-language automation for DIgSILENT PowerFactory using the Model Context Protocol (MCP).

This project lets an MCP client ask PowerFactory to run repeatable engineering tasks such as load-flow studies, bus-voltage extraction, line switching, three-phase short-circuit studies, and line N-1 short-circuit capacity sweeps.

Why this project exists

PowerFactory studies often require repetitive manual steps:

1. Change network state.
2. Run a calculation.
3. Export results.
4. Restore the original state.
5. Repeat for the next contingency.

This repository wraps those steps behind controlled MCP tools so engineers can request study workflows in natural language while PowerFactory remains the calculation engine.

Features

• MCP server for PowerFactory automation
• In-app PowerFactory Python agent for robust GUI-session control
• Load-flow execution
• Bus-voltage and line-loading extraction
• Line open/close control
• Three-phase short-circuit calculation at a selected bus
• Line N-1 short-circuit capacity study with CSV export
• Example innovation proposal PDF/PPT generation scripts

Quick start

Install dependencies:

python -m venv .venv312
.\.venv312\Scripts\python.exe -m pip install -r requirements.txt

Create a Python script in PowerFactory named MCP_Agent, paste the contents of:

src/powerfactory_mcp/agent.py

Run MCP_Agent inside PowerFactory. Then test the bridge:

.\.venv312\Scripts\python.exe .\scripts\test_bridge_connection.py

Configure your MCP client using:

mcp_config.example.json

Example result

The included example ran a line N-1 three-phase short-circuit study at Bus 5. The limiting case was:

Outaged line: Line 4-5
Ikss: 1.0144 kA
Skss: 404.09 MVA
