Interactive Optimal Power Flow Compiled to the Browser

Submitted, 2026.

This paper introduces tellegen, a frontend framework for interactive optimal power flow. The core solvers — DC optimal power flow, AC power flow, and a second-order cone relaxation — are written in Rust and compiled to WebAssembly, so exact solves run entirely in the browser: no server, no upload, no installation. Editing a demand or a line rating updates the solution and its KKT sensitivities live on a geographic map of the network.

Try it at tellegen.dev — drop in a case file, or load one of the built-in networks, including the CATS California Test System.
