Simulation Studies and Modelling Requirements

Simulation studies are crucial for design and operation of the power system and users’ simulation models are of importance for the computer-based assessment of the impacts of the installations on the network. Customers are required to develop accurate models of their facilities, conduct simulation studies using the models and submit their self-assessment studies to EirGrid within the defined timelines.
