17 EV/PHEVs used to implement Japan's largest EV power station experiment to demonstrate power grid stability

TOKYO, Mar 01, 2019 - (JCN Newswire) - As announced on June 6, 2018, Tokyo Electric Power Company Holdings, Inc., TEPCO Energy Partner, Inc., TEPCO Power Grid, Inc., Hitachi Systems Power Services, LTD., Mitsubishi Motors Corporation, Shizuoka Gas Co., Ltd. and Hitachi Solutions, Ltd. have been engaged in joint experiments to demonstrate the construction of a virtual power plant*. Today, the seven companies* reported the results of their V2G (Vehicle to Grid) demonstration experiment to the Ministry of Economy, Trade and Industry.

During this demonstration, the largest experimental environment ever built in Japan, to enable a two-way power exchange between electric vehicles (EV/PHEVs) and a power grid, was constructed at the East Shizuoka Prefecture Branch and Yoshiwara Station of Shizuoka Gas Co., Ltd. and at the Okazaki Plant of Mitsubishi Motors Corporation, and the demonstration confirmed that this technology will be effective in contributing to power grid stability.

In detail, it was confirmed that congestion can be managed (current control) by the output control of EV/PHEV power stations (EVPS) according to control commands.

In fact, since EVPS can be controlled and tracked on a second-by-second basis, we believe that output control can be realized in a matter of seconds in the near future even in remote areas through a combination with high-speed communications networks.

It was also confirmed that voltage control (reactive power control) can give output responses as signaled by control commands in the same manner as grid congestion management (current control).

By leveraging EV/PHEVs to improve power grid stability technology we can further promote the spread of naturally fluctuating power sources, such as solar energy, etc., and contribute to the flexible operation of power grids.
