6 FAQs about [Interpretation of Japan s microgrid structure]

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.

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.

How has Japan compared to Germany in the field of microgrids?

While Germany has seen initiatives in the field of microgrids, Japan has gathered more experience, including with regard to crucial aspects such as user approval and participation, different kind of energy management systems and data sharing.

What is an example of a microgrid?

A 12-kWp energy from PV and 85-kWh energy from battery bank are made available at the microgrid. Another example of AC microgrid is a 610-kW microgrid installed at Hachinohe, Japan. This microgrid consists of PV array, wind turbine, and controllable digester gas engines, as well as a battery storage of lead acid battery. 3.2. DC microgrid

How are microgrids transforming traditional electric power systems?

Traditional electric power systems are rapidly transforming by increased renewable energy sources (RESs) penetration resulting in more efficient and clean energy production while requiring advanced control and management functions. Microgrids (MGs) are significant parts of this transformation at the distribution level.

Why should Japan invest in microgrids?

In addition, Japan’s energy policy sees safety as one of the primary objectives since the Fukushima disaster of 2011. One approach is to improve resilience against disruptions. Here, microgrids as the technological foundation for smart communities play an important role.
