Mitsubishi Electric  has started its full-scale testing of smart grid in Japan, thus allowing customers to manage their electricity consumption in future.
The project focuses on the development of robust energy infrastructure that offers continuity in emergency situations, after the Great East Japan Earthquake. Since May last year, the company had been developing smart grid infrastructure worth about Rs.408.07 crore ($91 million) for balancing demand-supply; managing distribution network, total grid operation for the future and specific operation.  This will include analysis of technologies and algorithm to manage a large amount of renewable energy connected to the power grid , technologies and equipment for voltage control, to prevent instability caused by many PV systems installed in buildings and residences .Comprehensive evaluation of an envisioned environment in 2020 , technologies for independent micro grid such as island or partially connected regions will also be checked and test will 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.
