SITEM
Singapore Integrated Transport and Energy Management — systems-level research for urban mobility.
About the Programme
A*STAR’s Institute of High Performance Computing (IHPC) and TUMCREATE Ltd are working together on a research project that supports Singapore’s planning for the transition to electric vehicles (EVs) nationwide. The Singapore Integrated Transport Energy Model (SITEM) will be used to conduct a comprehensive analysis of projected electric vehicle (EV) charging patterns and energy demand, which will support policymaking on Singapore’s budget 2040 vision for all vehicles to run on cleaner energy and contribute towards Singapore’s decarbonisation commitments. The research project is commissioned by the Science and Technology Policy and Plans Office (S&TPPO), Prime Minister’s Office, and aims to advance the nation’s capabilities in integrated modelling and simulation of transport and power systems.
Singapore’s 2040 vision to phase out internal combustion engine (ICE) vehicles and have all vehicles run on cleaner energy will involve a large-scale, multi-agency effort to provide charging infrastructure, electrify public vehicles, and upgrade the electrical grid to accommodate the new demand. Designed to support this effort, SITEM is the first high-fidelity, island-wide simulation of EV transport in Singapore that integrates multiple aspects of mobility and energy modelling, including the movements of individual vehicles, drivers’ decisions about where and when to charge, and the interaction of EV charging demand with electricity grid capacity. Through advanced scenario modelling and simulation, the project aims to deliver insights on how Singapore can optimise EV charging stations’ placement to address drivers’ charging needs and to efficiently allocate energy demand and upgrades across the power grid.
The SITEM project builds on two primary simulation technologies developed by TUMCREATE in Singapore under its NRF-funded Mobility Programme:
- City Mobility Simulator (CityMoS) utilises high-performance computing techniques to enable high-detail transport simulation of the entire island of Singapore, while maintaining short turnaround times.
- Multi Energy System Modelling & 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).
