- NEDO Japan, The Los Alamos of Public Utilities and the Los Alamos National Laboratory teamed to develop smart grid technology, a test bed to solve the nations overburdened and antiquated power grid.

- Smart grids are new-generation electrical power networks that efficiently control and balance the supply and demand of power through digital information that integrates small and large-scale renewable energy sources.

- The Japanese government expects to invest $30 million over four years in smart grid research and demonstration projects in New Mexico.

- NEDO signed five agreements in Los Alamos with state officials and representatives from the two national laboratories, Los Alamos County, the Public Service Co. of New Mexico, and the Mesa del Sol master-planned community in south-central Albuquerque.

EMS and Constant Power Flow Control EMS and Constant Power Flow Control at Connecting Point in at Connecting Point in Los Alamos, NMLos Alamos, NMWith the coordinated EMS control of NAS and Lead-Acid batteries, fluctuation of generation from large scale installed sustainable energy (PV) is absorbed and power flow at the connecting point to the grid is maintained at a constant value.

•Actual demand (red line) is supplied by PV generation in daytime and power discharge from a battery stored in nighttime.Consequently, purchase of expensive power in daytime is reduced and less expensive power in nighttime is increased.

○ Energy management in larger areas is more effective than that in a single house .○ Excess electricity stored in battery in sunny areas can be transferred to houses that require

electricity. It is not necessary for a battery to be installed in an individual house. If one battery is installed for every few houses, then the installation cost will be decreased.

○ Demand in residential areas is larger in the morning and at night and demand in commercialareas is large in daytime , by transferring electricity between areas, electricity can be used effectively.
