qsim

A Rust library for power grid modeling and simulation.

Features

• Power Flow Analysis — DC and AC power flow solvers
• Modular Architecture — Pluggable solvers and elements
• High Performance — Pure Rust, parallel computation with Rayon
• Graph-Based Topology — Flexible network representation

Quick Start

use qsim::prelude::*;

// Create a simple 3-bus network
let mut network = NetworkData::new("Example");

// Add buses
network.buses.push(Bus::slack(1.0));
network.buses.push(Bus::pv(1.0, 50.0));
network.buses.push(Bus::pq(-100.0, -30.0));

// Add branches
network.branches.push(Branch::line(0, 1, 0.01, 0.1));
network.branches.push(Branch::line(1, 2, 0.02, 0.15));

// Save to JSON
network.to_file("network.json")?;

Crate Structure

• qsim-core — Core engine, traits, state management
• qsim-elements — Grid elements (Bus, Branch, Generator, Load)
• qsim-solvers — Power flow solvers (DC, AC)
• qsim-io — JSON I/O, serialization, persistence
