As the number of IBR sources in the GB system continues to rise, it becomes essential to conduct numerous Electromagnetic Transient (EMT) simulations across various scenarios and contingency cases to assess system stability. Consequently, there is an escalating demand for the development of the ability to perform multiple EMT analyses to facilitate broader network studies while keeping simulation times manageable and practical.

This project aims to develop innovative approaches for expediting simulation times required to execute the comprehensive GB EMT model. It will also offer technical insights to ascertain the imperative need for EMT simulations during critical system conditions.

Benefits

The project will enhance the GB network's EMT model by improving the models' computational efficiency, which will help investigate more scenarios with stability risks while transitioning into zero carbon operation. Additionally, it will offer technical recommendations to identify critical system conditions requiring EMT simulations.                                  

The learnings from this project will also be beneficial to Transmission Owners (TOs) concerning the run time of their respective EMT networks. The TOs use the same EMT software package, and the developed tool should be able to integrate with their models seamlessly. Furthermore, the second phase of the innovation project will produce technical guideline outlining the scenarios for which EMT simulations are necessary under system-critical conditions for better-informed decisions.
