Mitsubishi Electric Corp. began full-scale tests of smart grid and related smart-community technologies at its production sites in Japan, aiming for annual sales of 1.3 trillion yen (about US$17 billion) by March 2016. The company is developing commercial systems, equipment, and solutions for implementing a smart grid.

Mitsubishi aims to provide a system that enables consumers to visualize and control electricity consumption for optimized energy use. The project also focuses on the development of energy infrastructure that offers continuity in emergency situations, such as Japan saw after the Great East Japan Earthquake of 2011.

The company has been developing smart-grid infrastructure worth about 7 billion yen since May 2010, including systems for supply and demand management, next-generation distribution management, advanced metering, and energy management.

The full-scale testing will focus on four main areas:

• Demand-supply balancing: technologies and algorithms to manage a large amount of renewable energy connected to the power grid.
• Distribution network management: technologies and equipment for voltage control, to prevent instability caused by a large number of photovoltaic systems installed in buildings and residences.
• Total grid operation for the future: comprehensive evaluation of an envisioned environment in 2020, when a large volume of renewable energy will be connected to the network and electricity demand will be aggregated in communities.
• Specific operation: technologies for independent micro grid such as island or partially connected regions.

The tests will also focus on the verification of smart grid technologies performances in very severe conditions for the power system including loss of part of the grid by earthquake, lightning, and other weather related events.

Mitsubishi Electric is a manufacture of appliances, consumer electronics, information processing and communications, space development and satellite communications, industrial technology, energy, transportation, and building equipment.
