Smart electricity: "electricity 2.0" begins to warm up globally editor's note: in China, the integration of industry and informatization has become a trend, and the just passed revitalization plan for the electronic information industry will improve the informatization level of various industries. Smart electricity also needs to continuously integrate and integrate enterprise asset management and power production and operation management resources, so as to provide all-round information services for power planning, construction and operation management, which is another driving force for the development of smart electricity

smart electricity should cover all links of power generation, transmission, distribution and supply. It is not just the "last mile" connected to users. The word "Electronics" is hot in the United States. This is Jesse, head of the global smart energy program in the United States? Boster's masterpiece combining the words "electricity" and "economics". At present, he also plans to publish a book with great interest, tentatively titled "Electronics: how to promote American prosperity with smart electricity"

Jessibost pointed out that in 1950, 20% of U.S. GDP was directly dependent on electricity. Today, this proportion has exceeded 60%, and the future is more promising. The source of his confidence is smart electricity technology. As Obama continued to emphasize the establishment of a low-carbon and sustainable United States, and injected real gold and silver into smart phones in the economic stimulus plan, critics hailed the opening of the era of "electricity 2.0"

smart electricity in the United States

what is smart electricity

domestic and foreign research institutions have been immersed in research for several years. Although their research background, research focus and application scope are different, it has become a common consensus to use modern information technology to realize the intellectualization of electricity

in the U.S. recovery and Reinvestment Act of 2009, US $1.1 billion was used for the research of "smart power investment plan", but it has the disadvantages of high cost, long cycle and low efficiency. In 2007, the energy independence and security act of the United States also arranged a subsidy fund of $4.5 billion for smart electricity. In a report on the impact of technology investment on employment growth, Obama advisers analyzed that investing $10billion in smart electricity could create 239000 jobs. For the characteristics of smart electricity, Accenture defines the keywords as clean, strong, self-healing, optimization, interaction and economy. Experts from East China Power Co., Ltd. believe that smart electricity is aimed at the power system including all links of power generation, transmission, distribution and consumption, constantly developing new power control technology, information technology and management technology, and organically combining them to realize the intelligent exchange of information in all links from power generation to power consumption, and systematically optimize power production, transmission and use, which is a beautiful vision for the future development of electricity

environmentalists are convinced that smart electricity is green. It is said that every 5% increase in the efficiency of national electricity in the United States is equivalent to reducing the fuel consumption and carbon emissions of 53million vehicles. By 2020, smart electricity technology will help power enterprises reduce carbon dioxide emissions by 14%

what do people think of smart electricity

in China, people who care about it mainly come from the industry. In the open forum on smart electricity in the United States, we can see that the discussions of praisers and skeptics are in full swing. "Smart electricity is to install sensors in your home. What is in your refrigerator and how long you spend in the bathroom... Are monitored by others." This sci-fi description is hilarious, but it is not difficult to see that smart electricity is causing huge waves among American people

the obvious benefit is that with smart electricity, power companies can easily understand the power consumption of users, and can monitor and control various smart facilities in a remote way. Users can also understand the power supply, get energy-saving suggestions through smart meters, and no longer worry about power outages, because smart electricity has the ability to recover automatically. In short, electrical efficiency has improved. Not only the last mile, there are many current research hotspots on smart electricity: focusing on two-way interaction with users; Pay attention to the development and management of renewable energy and distributed power generation; Pay attention to the innovation of business model and technical means; Pay equal attention to research and application, and combine industry, University and research highly; Pay attention to power distribution and users

talking about the reasons why distribution intelligence is concerned, Dr. Yu Xujiang, a Chinese expert on smart electricity, said that there will be some difficulties in making smart electricity in the transmission part. Because the investment in the distribution system is small, it will be easier to see the effect soon. The situation in China is different. IBM suggested that due to the imbalance of economy, population and power supply and demand among regions, the availability, non discrimination and affordability of power supply pose challenges, which should be considered in the development of smart electricity in China

experts believe that China's total installed capacity will exceed 1.6 billion kw in 2020. The distribution of energy resources such as coal, water and wind and productivity is very unbalanced, which determines that China must take the road of large-scale material elasticity, which requires different experimental machine accessories for testing, centralized development and long-distance external power transmission, which urgently needs to build strong power

huxuehao, deputy chief engineer of the Chinese Academy of electrical Sciences, pointed out that the electrical architecture of western countries tends to be stable and mature, and now focuses on intelligent distribution; However, power transmission in China needs to be strengthened. Natural gas power generation has become a common practice in the United States, Britain and other countries, but in China, it is subject to fuel shortages. Europe and Japan develop household solar power generation devices, and China may install more in the western desert

for further development, we will focus on unidirectional (UD) fiber reinforced belts. Chen Wenlong, executive director of jusi China smart power, pointed out that smart power should cover all links of power generation, transmission, distribution and supply, and not just the "last kilometer" connected with users. Every country with a grand development plan for smart electricity should choose its own application module. China's power transmission has developed rapidly, so it should become the application field of smart electricity, and it is not necessary to focus on power distribution as some countries do

business opportunities "fooled"

Martinhauske, senior power expert of IBM in China, said that compared with the United States, the infrastructure of China's power industry is much more advanced, and China power is likely to catch up

but how to achieve the goal

as early as May 2000, Lu Qiang, an academician of the Chinese Academy of Sciences, put forward the viewpoint of upgrading the level of electrical automation in his famous paper "digital power system (DPS)", which seems to be applicable to today's intelligent electricity. He pointed out that DPS does not conflict with the existing energy management system (EMS). EMS can be regarded as the DPS in the primary stage. Just as the function of anti-aircraft gun is integrated into the ground to air missile, don't expect it to be achieved overnight. DPS is gradually developed and "available step by step"

"step by step" attracts Americans who can do business with everything. The expected service life of smart electricity in San Diego is 20 years. The calculation of its benefits shows that the annual income is about 142million US dollars, and the annual operation and maintenance cost is about 24 million US dollars. It is expected to achieve an internal rate of return of 44% and a net present value income of 410million US dollars. No wonder Google, which has the financial resources to launch satellites, has turned its attention back to the earth and started manufacturing smart meters

in the United States, governments, information-based enterprises and environmentalists are the first to be enthusiastic about the smart electricity revolution, while utility enterprises are not in the first place. Some people laughed and said that it was not difficult for experts to stay up late to make a report and lobby around, but I'm afraid it's not easy to "Huyou" power enterprises to comply immediately, carry out complex infrastructure construction, and even change the business operation mode. At the same time, it is estimated that it will take time to attract the deep participation of end users with real-time electricity prices

almost all experts are not opposed to the development of smart electricity. They believe that it should be led by the government, actively promoted by research institutions, power enterprises and information companies, and widely participated by the public. John, head of the UK energy research centre? Raufhead said that the popularization of smart electricity needs policy support and a large amount of investment from Japanese catalyst to increase the production capacity of acrylic resin for optical materials

the good news is that in China, the integration of industry and informatization has become a trend, and the revitalization plan of electronic information industry just passed will improve the informatization level of various industries. Smart electricity also needs to continuously integrate and integrate enterprise asset management and power production and operation management resources, so as to provide all-round information services for power planning, construction and operation management, which is another driving force for the development of smart electricity

"it won't take long" is usually the mantra of the information industry for unsolvable problems. Now, after the combination of information technology and the energy industry, the new beauty is "not long"? Perhaps, a fall in oil prices in the future is a signal that smart electricity will play a role
