Extensible framework for power system model translation

R2X Core is a model-agnostic framework for building power system model translators. It provides the core infrastructure, data models, plugin architecture, and APIs that enable translation between different power system modeling platforms like ReEDS, PLEXOS, SWITCH, Sienna, and more.

• Plugin-based architecture with automatic discovery and registration
• Support for multiple file formats: CSV, HDF5, Parquet, JSON, and XML
• Standardized power system component models via infrasys
• Abstract base classes (BaseParser, BaseExporter) for implementing model translators
• Type-safe configuration management with Pydantic models
• Built-in data transformations, filters, and validations
• Flexible data store with automatic format detection
• System modifiers for applying transformations to power system models

pip install r2x-core

from r2x_core import PluginManager, BaseParser

# Register your model plugin
PluginManager.register_model_plugin(
    name="my_model",
    config=MyModelConfig,
    parser=MyModelParser,
    exporter=MyModelExporter,
)

# Use it
manager = PluginManager()
parser = manager.load_parser("my_model")
system = parser(config, data_store).build_system()
