Abstract: Is artificial intelligence really required in the electricity sector? In this talk, we look at how AI techniques can aid the power grid transition by addressing the challenges posed by large-scale renewable energy integration. The efficiency of the power grid is specifically dependent on system operation and market design, and the stochastic nature of renewable generation fails the classical operation techniques and market designs. Fortunately, AI offers an intriguing solution for dealing with such failures by digitalizing the power grid. To that end, we will share three stories to show our AI-driven efforts toward a more efficient power grid. We begin with data acquisition and utilization in the power grid, which serves as the foundation for any AI method. We take user profiling as an example to show how privacy-preserving techniques can impact data utilization. The data-driven power system operation framework is then introduced, and the main challenges in designing an AI-aided toolbox are highlighted. Finally, using storage sharing in an industrial park as an example, we will briefly share our perspective on emerging business models in the electricity market.

Multi-Dimensional Manipulation of Solid/Liquid Interaction

Abstract: Solid/Liquid interaction play important role in many research and application fields. In this presentation, we will introduce a radically new strategy that resolves the bottleneck through the creation of an unexplored gradient in surface charge density (SCD). By leveraging on a facile droplet printing on superamphiphobic surfaces as well as the fundamental understanding of the mechanisms underpinning the creation of the preferential SCD, we envision that our work enriches and extends our capability in the manipulation of droplet transport and would find numerous potential applications otherwise impossible. We will also show that robust superhydrophobicity can be realized by structuring surfaces at two different length scales, with a nanostructure design to provide water repellency and a microstructure design to provide durability. We apply this strategy to various substrates—including silicon, ceramic, metal and transparent glass—and show that the water repellency of the resulting superhydrophobic surfaces is preserved even after abrasion by sandpaper and by a sharp steel blade. This design strategy could also guide the development of other materials that need to retain effective self-cleaning, anti-fouling or heat-transfer abilities in harsh operating environments.
