Exploring Stability and Accuracy Limits of Distributed Real-Time Power System Simulations via System-of-Systems Cosimulation

Electromagnetic transients (EMT) is the most accurate, but computationally expensive method of analyzing power system phenomena. Thereby, interconnecting several real-time simulators can unlock scalability and system coverage, but leads to a number of new challenges, mainly in time synchronization, numerical stability, and accuracy...

Unlocking system transitions for municipal solid waste infrastructure: A model for mapping interdependencies in a local context

Rapid global urbanization, urban renewal and changes in people's lifestyles have led to both an increase in waste generation and more complex waste types. In response to these changes, many local governments have invested in municipal solid waste infrastructure (MSWI) to implement circular strategies. However, matching and bridging the costly...

Identifying Stakeholder Perceptions of Overhead Catenary Electric Road Systems

Heavy-duty trucks (HDTs) are a significant contributor to global anthropogenic carbon emissions. In contrary to passenger cars, HDTs have to cope with decarbonization complications due to range and weight characteristics. Overhead catenary electric road systems (ERS-OC) can aid in decarbonizing this sector. Here, trucks are equipped with a...

Design of a Supply Chain Coordination System-of-systems: Applied to offshore wind power park maintenance

Due to the European Union renewable energy targets for 2030 and beyond, increasing trends of installed offshore wind energy production capacity and increasing wind turbine size emerge. Therefore, the offshore wind maintenance demand increases and becomes increasingly more complex. The most applied maintenance strategy is reliability-centred...

An integrated system approach to characterise a drinking water infrastructure system

The object of this article is the drinking water infrastructure (DWI), a critical societal infrastructure. To make effective decisions it is important to characterise and understand the complexity of DWI systems. DWI systems can be seen as a system of systems, consisting of the social-ecological system and the social-technical system. The...

Algebraic Connectivity of Interdependent Networks

The algebraic connectivity UN-1, i.e. the second smallest eigenvalue of the Laplacian matrix, plays a crucial role in dynamic phenomena such as diffusion processes, synchronization stability, and network robustness. In this work we study the algebraic connectivity in the general context of interdependent networks, or network-of-networks (NoN)....

Adaptive Policy Design to Reduce Carbon Emissions: A System-of-Systems Perspective

This paper presents an adaptive policy design approach based on a system-of-systems (SoS) perspective. Using a case of carbon emissions reduction in the residential sector, the SoS perspective is used as a way to structure the policy issue into interdependent relevant systems. This representation of the system provides a framework to test a...

System and Actor Perspectives on Sociotechnical Systems

This paper addresses the complexity of analyzing and designing sociotechnical systems: systems that involve both complex physical-technical systems and networks of interdependent actors. It is shown that, although a hard system perspective and an actor perspective differ greatly in terms of terminology, methods, and applicability, they also show...
