cobre-python 0.6.2

High-performance SDDP solver for hydrothermal dispatch — Python bindings for the Cobre ecosystem

cobre

Python bindings for the Cobre power systems solver.

Cobre is a high-performance SDDP (Stochastic Dual Dynamic Programming) solver for hydrothermal dispatch, written in Rust. This package provides Python access to case loading, validation, training, simulation, and result inspection.

Installation

pip install cobre-python

Pre-built wheels are available for:

• Linux x86_64 and aarch64 (manylinux_2_34), musl x86_64
• macOS Apple Silicon (aarch64) and Intel (x86_64)
• Windows x86_64
• Python 3.12+

Quick Start

import cobre

# Load and validate a case
system = cobre.io.load_case("path/to/case")
print(f"System: {system.n_buses} buses, {system.n_hydros} hydros, {system.n_thermals} thermals")

# Run training + simulation
result = cobre.run.run("path/to/case", output_dir="output/")
print(f"Converged: {result['converged']}, LB: {result['lower_bound']:.2f}")

convergence = cobre.results.load_convergence("output/")
print(f"Iterations: {len(convergence)}")

simulation = cobre.results.load_simulation("output/")
print(f"Cost records: {len(simulation['costs'])}")

policy = cobre.results.load_policy("output/")
print(f"Iterations completed: {policy['metadata']['completed_iterations']}")

Modules

• cobre.io — Load and validate case directories
• cobre.model — Data model classes (System, Bus, Line, Thermal, Hydro, etc.)
• cobre.run — Execute SDDP training and simulation
• cobre.results — Load and inspect output artifacts, including convergence history, Parquet simulation outputs, and FlatBuffers policy (FCF) checkpoints

Requirements

• Python >= 3.12
• No runtime dependencies (the Rust solver is statically linked)
