My research focuses on cyber-physical energy systems, by employing modeling, optimization, and control theories to design new algorithms and mechanisms for emerging technologies based on the internet-of-things (IoT), mobile sensing, and data mining, in order to facilitate the transition into an energy-efficient and system-wide resilient urban ecosystem.
To this end, I develop novel sensing paradigms for indoor environment monitoring and demand-based, occupancy-aware controls, as well as modeling and incentivization of humans to induce desirable behaviors (e.g., energy saving, demand response).
I also explore the design and operation of community-based micro-grid in support of the mega-grid, which exploits the flexibility of demands, as well as the efficiency from both thermal and electricity energy provision and shared distributed energy resources (DERs) and storages, to address the grand challenge of 20% renewable energy by 2020.
