International Symposium Renewables Integration into the Japanese Power Grid by 2030A Frequency Stability and Load Flow Analysis

17 December 2018

in Japanese

Integrating high shares of renewables, while reducing the share of conventional generation such as coal and nuclear power plants, bring new challenges to the Japanese power system. With the increase of variable renewables in Japan, concerns have indeed started to rise regarding their impact on grid stability and solutions have been investigated to incentivize sufficient flexibility in the system.

This study "Integrating renewables into the Japanese power grid by 2030", conducted jointly by Renewable Energy Institute and Agora Energiewende, investigates the potential of renewable integration in Japan from the viewpoint of frequency stability and power flows analysis. It is based on a modelling and simulating tool-chain of the Japanese power system developed by Elia Grid International and Gridlab for this project with the objective to facilitate independent research from third parties. Two scenarios were compared in the study for 2030: the government’s target scenario, and a more ambitious scenario.

On the occasion of the study report to be announced, this symposium focused on issues and challenges of the Japanese electricity system, with invited experts from Germany and Japan.
