Run relevant studies against the same network. openPowergrid checks the model first, skips studies that lack required data, and keeps every completed result in the case.

Study Case Results & Engineering Analysis
Dedicated case-analysis workspace. Select a case on the left, choose an engineering tool, inspect calculated results, findings, graphs and technical data.
Type a country, territory or region such as Germany, France, USA, Canada, Brazil, India, Japan, UAE, Saudi Arabia, EU, Asia, Middle East, South America or North America. Matching regulatory scope is shown below; project and utility requirements still depend on the supplied project data.

Regulation & Law Calculation Workbench
Adjust calculation inputs, factors and acceptance criteria for the selected regulation, grid code, utility rule or project engineering requirement. Every adjustable value is explicit; no legal limit is inferred automatically.
AI Connections & Engineering Assistant
Add local or cloud AI connections. AI is advisory only and cannot alter deterministic engineering results or certify compliance. AI cannot change calculated results, legal applicability, verification, or compliance status.
Saved AI connections
Connection settings are saved in this browser. API keys are never saved.
No saved connection selected.
Connection architecture
Browser-local connects directly from this browser to Ollama/LM Studio/llama.cpp/vLLM/LocalAI/Jan running on the engineer PC. This is the correct mode when openPowergrid itself is hosted elsewhere.
Ollama selected. For browser-local use, Ollama must permit this web origin. If the browser reports a CORS error, configure the local AI server to allow the openPowergrid origin.
Not connected.
Engineering safety: AI text is advisory. Numerical results come from openPowergrid/reference engines; regulation status comes from the verified regulation layer. Always review AI suggestions before engineering use. Privacy: Browser-local mode keeps AI traffic between this browser and the local model server; server-proxy mode sends the selected context through the configured provider.
Add 3rd Party — Engineering Evidence Library
Add standards, grid codes, manufacturer manuals, reference calculations and API datasets. Sources are evidence for review; ingestion does not make them authoritative or prove licensing/compliance.
Privacy & licensing: PDF/text/link snapshots are stored in the openPowergrid server workspace. You are responsible for rights to uploaded/licensed documents. API keys are used only for the import request and are never saved.
Source metadata
Add PDF
Text is extracted page-by-page so AI evidence can cite the uploaded page number.
Add public/trusted web link
Private/loopback server URLs are blocked unless the administrator explicitly enables trusted private networks.
Connect authorized manufacturer and multi-vendor catalogs, preview product records, then use your configured AI to source-ground and publish selected equipment into the shared server library. API keys, OAuth client secrets and bearer tokens are request-only and are never persisted.
Choose a connector or enter any authorized equipment API/feed URL.
No catalog fetched yet.
Built-in connector templates: Schneider Electric, TraceParts, Phoenix Contact API/BMEcat, Siemens, DigiKey, Mouser, Nexar/Octopart, Eaton, ECLASS, ETIM xChange, generic REST/JSON, GraphQL and XML/BMEcat. A preset does not grant API rights; use only credentials/data you are authorized to use.
Add Equipment to Shared Server Library — AI required
Upload a manufacturer datasheet/manual. Your configured AI extracts only source-backed equipment data; openPowergrid then checks the evidence and rejects duplicate datasheets or existing manufacturer/model/revision records. Published equipment is available to every user of this server. No login is required when authentication is disabled.
An AI connection/model must be configured before equipment can be contributed.
Trust model: community equipment is labelled AI_EXTRACTED_SOURCE_GROUNDED. It is reusable by everyone, but it is not automatically manufacturer-certified or standards-approved. Source SHA-256, pages, AI model and extraction evidence are retained.

Tick sources to prioritize them for AI calculation checks. Unticked means search all project/global sources.

Engineering Validation Lab
Numerical regression, release gates and advanced solver capability evidence. A module is never labelled ENGINEERING_RELEASE until every evidence gate passes.

External Conformance Evidence
Paste a JSON comparison pack from a published benchmark, commercial reference tool, independent lab or engineer. openPowergrid computes errors/tolerances itself and stores the evidence hash. Self-entered data is never called independent validation.
No external conformance evidence loaded.
Interoperability & Dynamic Model Checks
Run open-format round-trip regression and inspect the built-in open reference dynamic-model library. Commercial/standards interoperability still requires the corresponding external application/test lab.
Not run.
Protection Center
Protection devices, CT/VT connections, breaker/switch topology and protection studies for the active Study Case.
Protection Devices

Active Study Case
Protection Study Catalog
Add the exact protection calculation you need to the active Study Case. Only implemented/working study routes are runnable.
Breaker failure / reclose sequence screen — screening only
Supply measured or engineering-configured times; this does not emulate vendor firmware or authorize operation.
Enter real settings to screen event order.
Choose a protection study or inspect a protection device.
Engineering Study Center
Create named study cases and run several studies without losing previous results.

Web Project Workspace
Server projects, immutable revisions, audit evidence and storage health. Restoring a revision loads it into the browser; Save Project creates the next revision.
Pick an area, enter your actual evidence references as a JSON object, then check for missing mandatory fields. No files or claims are created automatically.
