Mathematical Approaches to Smart Energy & Information Systems Design
Embedded Files
We are trying to apply a wide range of technique and knowledge such as
Systems and Control Theory, Informatics, Big Data Science, Mathematical Optimization, Software Engineering
to designing a smarter energy system from the perspective of mathematical sciences.
A smart grid is a huge-scale cyber-physical system consisting of a number of events and phenomena at various spatiotemporal scales. For example, not only electromechanical characteristics of generators and transmission networks, but also weather conditions, natural disasters, human behaviors, commercial activities, and so forth are all essential ingredients in a smart grid.
Therefore, it is crucial to fully integrate a wide range of technique and knowledge such as
prediction of renewable power generation via machine learning
management of human behaviors based on behavioral economics
utilization of EVs and FCVs as a new energy carrier
UX design to enhance public consciousness about new energy solutions
as well as the control of traditional energy infrastructure. We are working on this challenging problem based on mathematical approaches.
