Abstract

The IEC 62559 Use Case Methodology and the Smart Grid Architecture Model Framework (SGAM) play a crucial role in energy-related national and European research and innovation projects, facilitating a shared understanding among stakeholders in ICT-based Smart Grid solutions. However, their adoption presents challenges due to the complexity and diverse expert backgrounds involved, which can lead to ambiguous IEC 62559 Use Cases and SGAM Models, and consequently, potentially wrong decisions in the implementation by inaccurate descriptions or models. This research aims to identify the challenges faced by IEC 62559 Use Cases and SGAM Model modelers, as well as their working processes utilizing the toolchain. To achieve this objective, a survey was conducted among domain experts and methodologists, who have experience in modeling IEC 62559 Use Cases and SGAM Models. The collected data will be subjected to qualitative content analysis. The findings aim to enhance the usage of the standard/framework and toolchain by improving the understanding of creators’ challenges. Additionally, the insights will support the development of future SGAM Models and IEC 62559 Use Case descriptions, thereby raising awareness of potential issues.
