Japan s Microgrid Control Technology

How will microgrids impact Japan's Energy Future?

As microgrids appear across the country, they will play an increasingly important role alongside the grid system to deliver clean and reliable power. Japan is currently aiming for 22%-24% of its energy to be produced by renewable sources by 2030, which will include 64GW of solar power.

Why does Japan need a microgrid?

The research on microgrid mainly focused on the use of microgrid to improve the quality of electrical energy and the reliability of power supply. Due to geographic location and other reasons, Japan is increasingly short of domestic energy.

When did microgrids start in Japan?

The first microgrids in Japan were New Energy and Industrial Technology Development Organization-financed projects initiated in Aichi, Kyoto and Hachinohe in 2003. A variety of energy sources were tested, in particular gas engines, and their success was demonstrated in the years that followed.

Should Japan invest in microgrids?

Japan’s Ministry of Lands, Infrastructure, Transport and Tourism has started a ‘Dam Revitalisation’ project that aims to bolster the country’s dam network as well as increase power from it.” For Japan to move forwards towards greater energy independence, resilience and lower emissions, microgrids appear a clear choice.

What is microgrid control technology?

The microgrid control technology should be a brand new, scientific, and effective technology for regulating and controlling various distributed units in the power grid. It can switch the working status such as grid-connected operation and island operation according to the need.

How many microgrids are there in Japan?

The total number of microgrids in use in Japan is currently unclear, though Kashiwagi puts the number of areas using the technology at close to 40. According to DeWit, “nobody seems to know, because there is poor governance on the PR side.
