DyCoV (Dynamic Compliance Verification) is an Open-Source tool built by RTE for bringing transparency to the process of verifying grid-code compliance of the dynamic behavior of new generation facilities. It contemplates both *electric performance* (i.e., "does the behavior pass the requirements?") and *generic model validation* (i.e., "does the model match the actual behavior?").

The tool builds upon Dynawo, RTE's Open-Source dynamic simulator, which in turn uses Open Modelica for its RMS models, including WECC and IEC generic models. This provides a fully transparent process for all stakeholders, thus avoiding the pitfalls of proprietary models and black-box tools. In addition, DyCoV removes the drudgery of measuring, comparing, and extracting all required KPIs from curves: rise/settling times, FRT responses, point-wise diffs, etc.

The tool is built with Python and structured as a series of independent tests, each producing its own report in PDF. The current tests correspond to RTE's connection grid code (DTR document), but DyCoV design uses templating (Jinja) and configuration files to make it easily adaptable to other grid codes, avoiding code changes as much as possible.
