powerio-cli

The powerio command converts formats, exports matrices and GridFM Parquet datasets, writes DC OPF bundles, generates synthetic cases, writes .pio.json documents, verifies matrices, and opens a ratatui interface. Transmission conversion covers MATPOWER, PSS/E, PowerWorld AUX, PSLF, PowerModels JSON, egret JSON, pandapower JSON, PyPSA CSV folders, GOC3 JSON input, Surge JSON, and GridFM reads. Distribution conversion covers OpenDSS, PMD JSON, and BMOPF JSON.

powerio

powerio sensitivities --solver iterative writes Matrix Market coordinates through temp files, so the command does not keep the full sparse PTDF/LODF output in memory.
