Development of a Roadmap to Integrate System Wide EMT Study Capabilities in Ireland

However, uplifting existing modelling processes to integrate wide-area EMT analysis capabilities in planning and operational engineering teams is not a straightforward task for most organisations. EMT modelling and simulation is more involved than the equivalent PDT, and requires higher skillsets, special computer software and hardware, new processes and procedures, more time and effort for data and model management, closer engagement with generator owners and OEMs, more extensive quality controls, etc. Once the models are deemed acceptable, the studies themselves require significant technical investment, and come with additional schedule and cost implications. This is a large undertaking involving many stakeholders, therefore it requires careful planning and co-ordinated efforts to deliver outcomes in a fair and timely basis.

In order to address those issues, the Transmission System Operators (TSOs) in Ireland and

Northern Ireland, supported by external partners, have developed a joint roadmap for the implementation of wide-area EMT study capability. As part of this work, a benchmark investigation was conducted to assess peer TSOs on their drivers and readiness to conduct widearea EMT studies.

This paper summarises the findings of the investigations and provides an overview of the developed roadmap along with its implementation status. It is hoped that the contents of this paper can be used as benchmarking by other TSOs embarking on a similar journey.
