エネルギーシステムの要求分析におけるMBSEの活用検討

抄録

In the current era of designing system of systems, the interconnection of various energy-related facilities and information control systems gives rise to new customer value, leading to the development of more attractive systems. This paper introduces an attempt to apply model-based systems engineering (MBSE) to the requirements analysis of energy systems, such as a hydrogen energy management power station. By emphasizing user experience (UX) design principles throughout the process, from deriving system requirements to evaluation, we ensure a human-centered design approach. System requirements are derived using context diagrams and use case diagrams to secure a user perspective. These requirements are then evaluated through operational optimization simulations focused on enhancing the overall user experience. Our company has developed an operational optimization tool that intuitively models user demands and challenges, such as those at power plants and factory power facilities, including carbon dioxide (CO₂) emission reduction, to find optimal solutions. By combining MBSE with UX design, we aim to refine the process of defining and evaluating system requirements, tailoring the engineering process to optimize the efficiency of design and operation for energy system development, thereby delivering customer value.
