Mobility-informed infrastructure planning
The demand for infrastructure like transportation, energy, and water highly depends on the spatial and temporal presence of people. Our research uses high-resolution, dynamic mobility flow predictions to improve infrastructure demand forecasts - particularly for energy systems. This enables both real-time operational support and long-term planning, particularly under stress conditions such as extreme heat.
Highlights:
New electricity demands from electric vehicle (EV) charging introduce significant challenges to the power supply infrastructure. This work introduces a methodology for modeling the spatial-temporal EV charging demand by leveraging mobility data. The detailed individual mobility patterns extracted from these data enable the simulation of district-level EV charging demand profiles, helping to identify critical areas that require grid expansion to accommodate this new demand.

This work investigates the potential of building-integrated photovoltaic (BIPV) and vehicle-to-grid (V2G) coupling for the city of Singapore. Using the city’s 55 planning areas as spatial units, a linear programming (LP) optimization model is developed to determine economically optimal PV scaling and (dis)charging strategies. Mobility flows between planning areas are assessed using a large set of GPS mobile phone records, from which electric vehicle (EV) schedules are derived.
