cimd is a Command line Interface for grid Model Data. It is a fast, safe and cross-platform tool for working with CGMES (Common Grid Model Exchange Standard) data.

cimd can be executed on Windows, MacOS and Linux from the command line or by chaining together commands in a script. Either to pre-process data for grid security analysis, or as a standalone tool to browse data.

cimd is implemented from scratch in Zig and has no other dependencies.

Performance

Throughput for a range of eq file sizes versus pyPowSyBl.

Features

Every cimd feature is based on the parser.

At the core of cimd is the parser, which processes raw CGMES profiles at 500MB/s on an M4 ARM chip. Every other feature is based on top of the parser.

Thanks to the lightning fast parser, cimd completes all its tasks in a glimpse. For example, converting a real-world, zipped 5MB node-breaker grid model to JIIDM under 200ms, as measured on M4 ARM chip.
