GUI Dashboard

Status: Experimental (Active Development)

A native desktop application for interactive power grid visualization and analysis, built with Tauri 2.0 + Svelte 5 + D3.js.

Features

Feature	Description
GridView	Force-directed network visualization with D3.js
Power Flow	DC and AC Newton-Raphson solving
DC-OPF	DC Optimal Power Flow with LMPs and congestion
N-1 Contingency	Single-branch outage screening with LODF
PTDF Analysis	Transfer sensitivity factors for bus pairs
LODF Matrix	Line Outage Distribution Factors for N-k analysis
Grid Summary	Bus/branch counts, MW totals, voltage ranges
Island Detection	Find disconnected network components
Thermal Analysis	Pre-contingency thermal headroom
Y-bus Explorer	Interactive admittance matrix heatmap
Batch Jobs	Parallel execution with progress tracking
JSON Export	Full network model export for external tools

Running the GUI

cd crates/gat-gui
pnpm install
pnpm tauri dev
