Research summary

Demand-side energy management system such as Home Energy Management System and Building Energy Management System, and Large-scale Electricity Storages are main research theme of the lab. The both technologies are important technology for Smart Community that fully utilizes various renewable energy. Energy consumption visualization is especially focused for the demand-side EMS for energy-saving and the load control based not only on economic gains and loss but also the belief on good will. The physical dynamic models for pump-hydro generation and compressed air energy storage are also developed to study their control abilities and strategies.
