美国智能电网优势显著 政府、法律起关键作用

US obtains advantages in smart grid

智能电网是目前国外物联网业务中的热点,这一方面是由于电力行业本身正处于技术变革的阶段,另一方面也是由于近期全球经济发展不景气,主要国家和地区纷纷将信息技术作为促进经济增长的手段。美国作为智能电网产业的领导者,其发布的政策和推行的应用备受关注。

Smart grid is the highlight of internet of things. As the leader in smart grid industry, the US have received great concern with regard to its related policies and applications. Currently, US Department of Energy (DOE)’s Electricity Delivery and Energy Reliability Office has been spending the smart gird investment in the related projects, among which the two biggest ones are named 'smart grid investment grant (SGIG)' and 'smart gird demonstration program (SGDP)'. Both of the projects have obtained certain achievements. By the third quarter of 2011, in SGIG remote meter reading project, the quantity of smart meter devices procured reached to 7.677 million, which accounted for 66% of the total investment of remote meter reading systems. From the experiences of US, we can see that the key elements in the construction of smart grid are the government’s attention, promoting mechanism and the legislation to ensure related investment. China should fall to doing from these aspects to vigorously promote the development of smart grid, and further turn from analysis of concepts and ideas to the actual deployment in each field of internet of things as soon as possible.
