Mitsubishi launches D-SMiree, turns over green leaf

28 Jul 2016

Mitsubishi Electric have just launched D-SMiree for medium and low voltage DC distribution.

All product development and testing, as well as the exhibition and promotion of direct-current distribution systems will be handled at the DC Development and Demonstration Facility.

The company expect D-SMiree sales for MV/LV DC distribution systems to reach 10 billion yen or approximately US$94.1 million by 2025.

According to Mitsubishi, a growing focus is being cast on solar-power generation systems, in line with the increasing importance of data centers and cloud services.

“Consequently, environmentally conscious direct-current distribution systems that combine renewable energy and electrical accumulators are gaining popularity,” a company statement read.

The company also states that it’s been contributing to the growing direct-current ecosystem. This has been accomplished by leveraging technologies that it originally developed for DC power generation and data center energy systems.  

Mitsubishi says the new facility will develop next-generation MV/LV DC distribution systems for DC power distribution. This is based on enhanced reliability, environmental friendliness and cost efficiency.

There will be advanced smart-grid technologies and storage-battery systems incorporated, which Mitsubishi say will be enhanced, extra-efficient solutions for purposes including the following:

  • Power generation — Easy interconnection of diversified renewable energy sources such as solar, wind, and fuel cells, without the need for electrical synchronization
  • Energy storage — Highly efficient operation of storage batteries by leveraging Energy Management System power-generation and demand-forecast functions
  • Efficiency — Reduced electrical loss through reduced power conversion compared to traditional AC distribution systems

Eventually the D-SMiree lineup will include 380V systems that are currently undergoing verification testing. The 1500V systems are expected to be introduced to the global market within the next year.
