Major Researches

Autonomous demand area power system technology for large-scale penetration of distributed power generation

To help create a low-carbon society, SERL proposes advanced infrastructure for the supply and demand of electric power (next-generation grids: TIPS). As part of this work, it is developing technologies for the smooth and efficient large-scale penetration of distributed power generation such as photovoltaic system into the distribution systems (Autonomous demand area power system). The project aims to maximize the use of renewable energies while ensuring the stability and safety of the power system by controlling not only distributed power generation but also customer loads and other equipments such as heat and electricity storage devices.

Low-loss compact power conversion technologies

In the low-carbon society in the future, power electronics will play an increasingly important role. SERL is conducting R&D for reducing the loss, decreasing the size and improving the control capability of power electronics system by using silicon carbide (Sic) devices. This will improve the energy efficiency of electrical equipment and reduce the life cycle cost.
