Realistic μPMU Data Generation for Different Real-Time Events in an Unbalanced Distribution Network

Haleem Medattil Ibrahim, M.I. (author), Sharma, Madhu (author), Subramaniam Rajkumar, Vetrivel (author)

Monitoring, protection, and control processes are becoming more complex as distributed energy resources (DERs) penetrate distribution networks (DNs). This is due to the inherent nature of power DNs and the bi-directional flow of current from various sources to the loads. To improve the system’s situational awareness, the grid dynamics of the...

Human Digital Twin, the Development and Impact on Design

Song, Y. (author)

In the past decade, human digital twins (HDTs) attracted attention in both digital twin (DT) applications and beyond. In this paper, we discuss the concept and the development of HDTs, focusing on their architecture, key enabling technologies, and (potential) applications. Based on the literature, we identify personal data, model, and interface...

Predictive Aircraft Maintenance: Integrating Remaining-Useful-Life Prognostics into Maintenance Optimization

Lee, J. (author)

Current aircraft maintenance ensures safe and reliable flight operations based on inspections repeated at fixed time intervals. The time interval between inspections is often much shorter than the average life of aircraft components, in an effort to timely detect potential failures. While this approach successfully prevents most potential...

Simulating industrial symbiosis: Understanding and shaping circular business models for viable and robust industrial symbiosis networks through collaborative modelling and simulation

Lange, K.P.H. (author)

The European Commission aims for a full circular economy (CE), an economy that aims to reuse all resources in 2050. CE is a promising way to increase welfare and wellbeing while decreasing environmental footprints. Industrial symbiosis, in which companies exchange residuals for resource efficiency, is essential to the circular transition....

Modelling Energy Security: The Case of Dutch Urban Energy Communities

Fouladvand, J. (author), Verkerk, D. (author), Nikolic, I. (author), Ghorbani, Amineh (author)

Energy communities are gaining momentum in the context of the energy transition. Given the distributed and collective action nature of energy communities, energy security of these local energy systems is more than just security of supply and related to issues such as affordability and acceptability of energy to members of the community. We build...

Institutional modelling: Adding social backbone to agent-based models

Ghorbani, Amineh (author)

Institutional modelling is a branch of agent-based modelling and simulation (ABMS) that pays special attention to the social structure by incorporating institutions into these models. Institutions, in this regard, are the rules of the system that shape individual behaviour and interaction. Institutional modelling can make use of the...

Open Experimental Data-Sets to Reveal Behavioural Insights of High-Deck Coach Evacuations

Huang, R. (author), Zhao, Xuan (author), Yuan, Y. (author), Yu, Qiang (author), Daamen, W. (author)

Numerous evacuation performance data for the utilization in evacuation modelling and simulations have been established for the conventional/widely studied scenarios, such as building evacuation scenarios. However, such data are typically scarce for a new scenario in literature — evacuation from high-deck coaches. This paper fulfills this gap...
