New Challenges for Future Energy Management Systems Using Electrified Vehicles
Prof.Dr. Tatsuya Suzuki
Professor, Nagoya University, Japan
Abstract
One of the promising ideas to realize a resilient energy management system (EMS) is to exploit the distributed batteries installed in electrified vehicles. This plenary talk gives several achievements on how to exploit in-vehicle batteries for EMS, which were developed under the operation of JST, CREST project in Japan. The following three significant challenges are particularly focused in this talk: (1) Observation and modeling of vehicle use, and its application to prediction and diagnosis, (2) Design of local EMS, such as vehicle to home (V2H), based on model predictive control framework, (3) Design of EMS aggregator which realizes the cooperation of distributed local EMSs. In the challenge (1), development of prediction model for future vehicle use is addressed based on semi-Markov model, and its performance is verified. In the challenge (2), simultaneous use of in-vehicle battery and heat pump water heater (HPWS) is considered, which enables us to realize highly efficient home energy management system. The challenge (3) is one of the most significant contributions in the CREST project, in which a design of response to regulation market (ancillary service), integrated management of EV sharing system and EMS, and design of price for P2P power trading in the cooperation between local EMSs, are investigated. All challenges include not only theoretical developments but also practical feasibility analyses. Finally, several important future works will be discussed.

Combinatorial Optimization Makes Your Daily Life Efficient
Prof. Dr. Mutsunori Yagiura
Professor, Nagoya University, Japan
Abstract
When you go out for shopping, visiting several stores, you might think of finding an “efficient” route to visit all stores in the sense that the total traveling distance or time is as small as possible. Such problems can be modeled as combinatorial optimization problems. Unfortunately, it is known to be hard to find optimal solutions for such problems, but there are still needs to solve them due to their practical importance. Fortunately, this difficulty is alleviated if we do not stick to exact optimal solutions. Indeed, many methods have been devised to find “good” solutions in reasonable computation time. This talk introduces the basic ideas of such practical algorithms, using examples from optimization problems closely related to your daily life.

Present and Future Biometric Research, Thailand’s Perspective
Prof. Dr. Vutipong Areekul
Professor, Kasetsart University, Thailand
Abstract
Several Thai government agencies have extensively used biometrics for a long time. However, the present biometric technology is still far from satisfactory. Many problems arise, including the current COVID-19 situation, and the biometric research paradigm has changed. This talk focuses on three main topics as follows. First, an overview of biometric usages in Thailand and some popular biometric traits are discussed. Second, The current biometric research problems, especially human identification using latent fingerprints, are introduced. Some existing and upcoming solutions are demonstrated. Finally, this talk ends with some existing and challenging biometric issues for future research.
