Profile Tatsuhito Nakajima received his B.S., M.S, and Dr.Eng. degrees from the University of Tokyo, Tokyo, Japan, in 1985, 1987, and 1990. He joined Tokyo Electric Power Company in 1990. His main works were R&Ds on applying power electronics for power systems, including HVDC, STATCOM and grid-connected inverters. He joined Tokyo City University as Professor in 2016. His research topic covers control technologies for multi-terminal offshore high-voltage dc transmission systems and grid-connected inverters of renewable energy sources and battery storages. Tatsuhito Nakajima is a member of IEEE, IEE of Japan and CIGRE.
Research Field(Keyword & Summary)
  1. (1) Grid-forming inverter control for improving power system stabilty

    With increase in renewable energy sources such as photovoltaic generation and wind power generation, power system stability is being deteriorated and the grid frequency fluctuations are getting worse. For improving power system stability, the contol strategies of the grid-forming inverter are being researched.

  2. (2) Offshore multi-terminal offshore high voltage dc ransmission

    Offshore wind farms are being commissioned in the world and multi-terminal high voltage dc transmission (HVDC) is a promising method for long-distance bulk power transmission from the offshore wind farms to the onshore load centers. Control and operation schemes for the multi-terminal HVDC are being researched.
