CityMoS Representation at ITAP 2022


CityMoS was part of the 2022 Industrial Transformation ASIA-PACIFIC (ITAP), Asia-Pacific’s leading Industry 4.0 Event, which took place from 18-20 Oct 2022 at Singapore EXPO. This year’s event was themed “Industry 4.0 for Business Sustainability”, which explored trends and developments in digitalisation, talent and workforce development and environmental sustainability – key in shaping sustainable business development for the advanced manufacturing sector, both locally and on a global stage. 

As part of the Industry Connect Talks at ITAP, we were given the opportunity to co-present the CityMoS involvement in the “Singapore Integrated Transport and Energy Model” project. Dr Jiajian Xiao provided an overview of how CityMoS was deployed to model and simulate the complex human driving and charging behaviors within the SITEM Project. 

About the SITEM Project:  

Commissioned by the Prime Minister’s Public Sector Science and Technology Policy and Plans Office (S&TPPO) and in collaboration with all relevant agencies, researchers from TUMCREATE and A*STAR’s Institute of High Performance Computing (IHPC) set out to create the first high-fidelity, island-wide simulation of electric vehicle (EV) transport in Singapore, called SITEM, short for Singapore Integrated Transport and Energy Model. 

SITEM integrates multiple aspects of mobility and energy modelling, including the movements of individual vehicles, drivers’ decisions where and when to charge, as well as the interaction of EV charging demand with the capacity of the power grid. The project conducts a comprehensive analysis of projected electric vehicle charging patterns and energy demand to support support policymaking on Singapore’s budget 2040 vision for all vehicles to run on cleaner energy and contribute towards Singapore’s decarbonisation commitments.  

The SITEM project builds on two primary simulation technologies developed by TUMCREATE in Singapore:  

  • CityMoS, the City Mobility Simulator utilises high-performance computing techniques to enable high-detail transport simulation of the entire island of Singapore, while maintaining short turnaround times. This enables the efficient exploration of wide parameter spaces.
  • Multi Energy System Modelling and Optimisation (MESMO) is an advanced software framework that combines simulation of electrical grids and optimisation techniques to mitigate the grid impact of distributed energy resources (such as photovoltaics) and new types of loads (such as EV charging). 

The live coupling of the mobility simulator CityMoS and the power grid simulator MESMO provides insights into the inter- dependencies of both systems. These advanced scenario modelling capabilities have enabled regulatory agencies to explore and evaluate various pathways to vehicle electrification. SITEM makes it possible to estimate the efficiency gains from such systems and to model their impact alongside or in combination with other mechanisms such as incentive-based demand shifting, smart scheduling, and local energy storages. 

The SITEM Team, including TUMCREATE researchers, has received the prestigious Borderless Silver Award 2022 in the annual Firefly Awards by the Ministry of Trade and Industry, Singapore (MTI). The annual Firefly Awards celebrate the best of ideas as well as recognise teams and individuals within the MTI Family who have exemplified strengths in the respective Award categories.
