billion by 2030 just for China alone,” Ipsen said. “A lot of the big companies –
the traditional GEs, IBMs, Siemens and others e are over there exploring that
market.”
For example, the introduction of technology of smart appliances could turn
on and off themselves as provided by both the energy management and the
smart grid. This technology could help the grid to support a fleet of electric
cars. The smart grid would improve the efficiency of transmission power.
Fig. 6.6, which is an expanded version of Fig. 6.5, shows a smart integrated
energy system that merges Internet and grid features. This system has a smart
grid with the power source(s), the data response, and a load center such as a
residential home. Fig. 6.6 illustrates several concepts including data collection,
communication, control, and smart grid system. A smart meter collects power
usage data for the utilities and consumers, and it has Internet communication
capability as mentioned previously.
The real-time data are fed back to a large distribution and transmission
power grid. Moreover, the energy storage that assists in load-leveling for
transmitting any major power activities comparable to a typical locally rated
load center is extremely important. For example, a major power activity could
