U.S. Smart Grid startup flexible adjustment of new energy power projects

The current U.S. power grid can be described as a human engineering wonders, some people think it is the world's largest and most complex single machine. Although this machine is only 40 years of age, but it suffers from incurable "rickets." Some data indicate that the U.S. power grid power interruption emerging problems, caused economic losses of up to an annual $ 150 billion. But the Americans are pleased that in the near future, the U.S. power grid issues expected to be resolved, because in the United States enacted economic stimulus plan, the government proposed the establishment of a new smart grid goals.

According to U.S. President Barack Obama's economic stimulus plan approved, the government will allocate $ 11 billion for smart grid technologies to help implement smart grid research and demonstration projects. Some experts said that regardless of the economic stimulus plan how much to invest in the power line, building flexibility to divert power supply smart grid will undoubtedly be called ambitious proposition. However, if you want to achieve carbon emissions, then the U.S. will have no other choice, because the current U.S. power grid can not afford a lot of manipulation to provide electricity from clean energy.

In a way, building smart grid is because the need for new high-voltage lines to those of the U.S. renewable energy-rich areas and densely populated cities and suburbs connected. American Southwest sunny desert areas, the potential for solar power generation capacity of up to 4,000 gigawatts. However, no new high voltage power lines, even if a lot of use of solar power gridtiepowerinverteronline output can not be delivered to the required power supply western coastal cities. North American Great Plains to provide the nation's wind power generation can be used more than 50%, and only rely on new power grid, but also to the potential of wind energy supply to other areas.

However, the use of solar and wind power is that there is a fundamental problem with fossil fuels differ, the majority of renewable energy can not be carried out according to the demand for energy artificially switch control. Only in wind power plants to generate electricity when the wind; solar power plants only when there is sunlight to provide power.
