Summary
This paper presents the development, validation, and operational deployment of a large-scale electromagnetic transient (EMT) model of the Scottish transmission system to support planning, operability, and Grid Code compliance studies under high inverter-based resource

The contributions of this work include: (i) scalable network partitioning and parallel execution strategies enabling 20s wide-area EMT simulations within planning timescales; (ii) robust integration of multiple vendor-specific EMT models using staged initialisation and multi-rate simulation; and (iii) application of the model to system-level stability, compliance, and impedance-based oscillation screening studies. Practical lessons learned from model conversion, validation, performance optimisation, and operational use are provided to support other transmission system operators developing network-scale EMT capability.
