Department: Electrification Suite & Test Lab
Closing Date: Open until filled
Hours: Full Time
Duration: Fixed term (6 months)

TUMCREATE is a research platform for the improvement of Singapore's public transportation, including the deployment of electric and autonomous mobility. Researchers from Technical University Munich and Nanyang Technological University join forces and are funded by Singapore’s National Research Foundation as part of the Campus for Research Excellence and Technological Enterprise (CREATE).
In TUMCREATE, over 100 scientists, researchers and engineers work together, led by Professors from the Technical University of Munich and Nanyang Technological University. The Mission of
TUMCREATE is to seek the ultimate public transport system for the people of Singapore. Our
innovative road transport solutions will provide high comfort and a positive travel experience, best protection of the environment and maximum benefit to the society and the economy.

About this Position
The research group Electrification Suite & Test Lab (ESTL) research area in TUMCREATE puts an emphasis on the interaction of the electricity grid with advanced electrified public transport systems for Singapore. Ranging from charging infrastructure optimisation to demand side management and integration of renewable energies, ESTL covers many hierarchy levels of the electrification concept in the context of the major goals of TUMCREATE.
A research project has been established to investigate electric demand side flexibility (DSF) in the airconditioning systems of office buildings, as demand response (DR) is becoming an important tool for the power system operation. In this project, control-oriented building models and model predictive control frameworks have been investigated. The results show that office buildings can provide DSF. However, a limitation for the flexibility is the requirement to provide a fixed amount of fresh air to ensure sufficient indoor air quality (IAQ). To this end, demand controlled ventilation (DCV) is proposed to increase the flexibility. With DCV, the fresh air supply is not fixed, but is controlled based on the current IAQ. For this, IAQ is measured through e.g. the CO2 concentration.
The goal of this master thesis / internship is to investigate how DCV can help to increase the DSF. The main tasks are 1) to formulate an expression & sensing concept for IAQ - based on which DCV can be operated, 2) to integrate the expression for IAQ into the existing models and the DCV method into the control frameworks 3) quantify the change in the DSF with the proposed approach.

  • Good understanding of air-conditioning systems and indoor air quality / environment quality
