Future-generation power network Stabilization Technology development for utilization of Renewable Energy As the Major power source (STREAM Project)

Project overview

Project period: FY2022 to FY2026, FY2022 budget JPY: 1.54 billion
PL: UEMURA Satoshi (Senior Research Scientist, Program Manager, Strategy and Planning Division ENIC Division Grid Innovation Research Laboratory, Central Research Institute of Electric Power Industry)
SPL: BABA Jumpei (Professor, Graduate School of Frontier Sciences Department of Advanced Energy, The University of Tokyo)

In October 2020, the Extraordinary session of the Japanese Diet declared the goal of achieving carbon neutrality by 2050, and in October 2021, the Sixth Strategic Energy Plan approved by the Cabinet indicated that the share of renewable energy would be around 36-38% in 2030.

The importance of expanding the introduction of renewable energy is increasingly being acknowledged. In order to expand the introduction of renewable energy, the Sixth Strategic Energy Plan follows the Fifth Strategic Energy Plan in "overcoming grid constraints" for "making renewable energy the main source of power", with the expectation that this will be realized through research and development.

This STREAM project, based on the results obtained from the NEDO project called "Next-Generation Power Network Stabilization Technology Development for Large-Scale Integration of Renewable Energies", aims to develop technologies to address new challenges like low inertia and short circuit capacity while comprehending the latest technological and policy trends, taking into consideration any possible technological or even institutional risks in the future power grid.

In addition, it will be verified that the results of the development are appropriately effective in small-scale power grids.
