Power Systems Wiki
An open wiki for power systems engineers, researchers, and students.
Introduction
This open-access wiki is designed to help power system professionals, researchers, and students quickly find clear, concise definitions of key terms and acronyms in the industry. Whenever a concept has multiple interpretations—whether in academic papers, technical standards, or industry reports—our goal is to present relevant definitions side by side, with citations to the original sources.
How to Use
Basic Usage
- Browse or search: Navigate via the wiki or use the search bar to locate terms instantly.
- Compare definitions: Some entries include excerpts from multiple sources—standards, peer-reviewed papers, and industry guidelines—so you can see how usage varies.
- Stay current: Terminology evolves as the field advances. We update entries regularly; check back for the latest additions and revisions.
- Contribute: Spot an error, omission, or new term? Please open an issue or submit a pull request on our GitHub repository.
REST API
The PS-Wiki REST API provides read-only access to term data in JSON format. It is deployed via Cloudflare Workers and documented using the OpenAPI 3.1.0. Base URL: https://pswiki-api.jinninggm.workers.dev
No authentication is required — all endpoints are public and read-only.
Endpoints Overview
| Method | Endpoint | Description |
|---|---|---|
| GET | /v1/terms | Search or list PS-Wiki terms |
| GET | /v1/terms/{id} | Retrieve a specific term by ID |
| GET | /v1/tags | List all tags and their term counts |
| GET | /v1/changes | List terms updated since a given timestamp |

Why This Wiki Exists
Language is inherently ambiguous, and power system terminologies are no exception. Inspired by an email titled “Definitions of Smart Grids a Decade Ago – What Has Changed?” on Power-Globe in 2024, I decided to compile terminologies from papers, standards, reports, and other traceable sources to build this wiki.
Disclaimer
- Not a primary source: We quote and cite definitions from existing standards, papers, and reports.
- Not exhaustive: Some important terminologies may be missing.
- Not rigorous: The terminologies are not rigorously proven mathematical theories.
- Subject to change: As power systems evolve, definitions may be updated.
