Practical Application of Energy-Related Use Case Methodology and SGAM Framework: A Study of User Perspectives and Challenges

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 identifies the challenges faced by IEC 62559 Use Cases and SGAM Model modelers, as well as their working processes utilizing the toolchain. To achieve this, a survey was conducted among experts experienced in modeling IEC 62559 Use Cases and SGAM Models, followed by qualitative content analysis of the collected data. The findings enhance the usage of the standard/framework and toolchain by improving the understanding of creators' challenges. The results aim to enhance both energy-related and methodological research projects by leveraging modelers' insights into project conditions and processes. This includes ensuring that required information are available on creating, establishing collaborative structures for SGAM modeling, and advancing the maturity of the Use Case Management Repository. The insights support the development of future qualitative SGAM Models and IEC 62559 Use Case descriptions, thereby raising awareness of potential issues.
