June 13, 2019: The second stage of a project to test vehicle-to-grid technology on Japan’s grid began on June 3 after the country’s Ministry of Economy, Trade and Industry, approved plans by a consortium of power, gas and vehicle OEMs.
It is the second time the companies have participated in this project; this time 40 additional electric vehicles/Plug-in Hybrid EVs (for a total of 59 EV/PHEV vehicles) will be added to create the VPP.
Trials at five locations within Japan will continue through to February 17, 2020, after the consortium was granted cash to cover the costs of the FY2019 virtual power plant construction demonstration project.
The consortium — made up of Tokyo Electric Power Company Holdings, TEPCO Energy Partner and TEPCO Power Grid, Mitsubishi Motors Corporation, Hitachi Systems Power Services and Shizuoka Gas — will investigate demand-side energy resources during the project.
The project will investigate how EVs used as a virtual power plant can balance the supply of renewables on the power grid.
The consortium will adjust power supply and demand through a two-way power exchange between the accumulators in EV/PHEV and power grids.
