Smart electricity: a new engine for future economic growth

when mankind gropes hard in the dark, power technology brings light to mankind; When smart electricity is about to come out, electric energy will create more gospel for the world. As another network that may cover the whole world after the Internet, smart electricity brings people the magic of chasing dreams and infinite imagination

the era of electricity 2.0

for many people, smart grid is still a unfamiliar or even unfamiliar word. In fact, like interconnection, smart electricity is also a truly interconnected, interconnected and interactive network, but in addition to data transmission and computing, smart electricity also transmits real energy. Compared with traditional electricity, the industry often refers to smart electricity as the second generation electricity or electricity 2.0 era

literally, smart electricity is the intellectualization of electricity, and its key is the supply and demand of electricity, the distribution and use of electric energy, and the connection between displacement and electronic information technology. Just as interconnection has caused significant changes in human life and production methods, smart electricity will also trigger a new revolution in the allocation and use of electricity in the real world and daily life

for power generation enterprises and transmission systems, smart electricity means a real-time monitoring system, which can not only easily understand the power consumption of users, but also remotely monitor and control various power facilities. If a large power artery fails, electric energy can be immediately transmitted from the alternative line to ensure that the power outage will never happen. In addition, after an accident in the traditional transmission system, consumers usually need to call the power company for repair, and then the power company will check and repair. This passive situation is impossible in smart electricity. Because the intelligent power system can collect the power transmission information in real time, identify the potential accident after calculation, processing and analysis, so as to send an alarm in advance to ensure the safe operation of the system; In addition, because the networks among power companies, houses and enterprises are interconnected, after the completion of smart electricity, power companies will no longer visit or entrust others to check electricity meters, which can greatly reduce the cost of customer service

for consumers, the magic created by smart electricity is far beyond people's imagination. First of all, the price of household electricity will be automatically priced according to different periods of the day. Residents can avoid the high price of electricity during the peak period of power consumption and reduce the cost of electricity; Secondly, consumers can see the power consumption of the whole city and different regions, and realize the purchase of electricity in different places. If they are not satisfied with the local electricity price or service, residents can choose to supply power thousands of miles away; Thirdly, residents can also know the status of household or personal electricity consumption and real-time price and service information through computer networks; Finally, residents can buy and sell electricity like buying and selling stocks. The surplus electricity of ordinary households and small business users can be sold to neighbors through smart electricity or other power users who ensure the stability and reliability of products. What is more interesting and surprising is that the operation of smart electricity means that all electric vehicles can enter. Therefore, in the smart electricity mode, people can see many charging stations on both sides of the road, which can charge electric vehicles and hybrid electric vehicles just like the current car gas stations

new energy revolution

if the invention of power technology is a landmark revolution in the development and utilization of energy, then smart electricity will cause no less changes in the field of energy than the former

the most significant function of smart electricity is to realize the stable and effective use of clean energy. The essence of smart electricity is energy substitution and compatibility. From the perspective of utilization, clean energy can be used more effectively only when it is transformed into electricity. However, different from fossil energy, solar energy and wind power generation have unstable and discontinuous characteristics, and will cause the decline of power quality. In this way, the efficiency of wind power is low, which restricts the development and utilization of wind energy. On the basis of smart electricity, the weakness of solar and wind power has been effectively eliminated, and the effective optimal allocation of energy resources has been achieved

taking China as an example, by 2020, China's installed capacity of wind power will reach 35million kW and 150million kW respectively, the installed capacity of solar power will reach 1million kW and 20million kW respectively, and the installed capacity of nuclear power will reach 10.5 million KW and 86 million KW respectively. The three installed capacities account for about 16% of the total installed capacity of electricity. With the support of smart electricity, this part of new energy will be used to the greatest extent without injuring personnel and damaging equipment

it is an indisputable fact that traditional power stations cause energy waste and loss. However, if China realizes the transformation of smart electricity, 226 million tons of raw coal can be saved every year

not only that, on the basis of saving energy consumption, smart electricity has obvious effect on effectively controlling and reducing greenhouse gas emissions. It should be said that the promotion of smart electricity is an important step to improve energy independence. It can reduce human dependence on fossil fuels and reduce greenhouse gas emissions. According to the research results of the smart electricity alliance of the United States, 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. In China, smart electricity technology is expected to help power enterprises reduce carbon dioxide emissions by 14% by 2020

powerful engine of economy

the limitation of traditional energy and the uneconomical development and use process have greatly restricted the normal growth pace of the global economy, while smart electricity has realized the replacement of energy, which not only expands the space for human energy utilization, but also brings the prosperity of related industries, and its traction on the economy is self-evident. Smart electricity first urges and drives the new energy industry. In addition to stimulating the development of traditional industries such as power and communication, smart power will develop and derive emerging technologies in the construction process, and promote the evolution and formation of emerging industries such as wind power industry, solar energy industry and new energy automobile industry. Therefore, the new energy industry around the construction of smart electricity will become the focus of economic competition among countries

in terms of market, the shipment of power batteries in China has increased from 0.66gwh to 30.8gwh, which undoubtedly creates new business and competition space for enterprises. It should be said that smart electricity provides the giants of the Internet era with the opportunity to participate in the transformation of the largest heritage of the industrial era for the first time, and it is precisely so that international IT giants have been put on the battlefield. For example, IBM has taken the lead in developing intelligent electricity meters, which can calculate electricity consumption and electricity charges in real time; Google has successfully developed an application software that uses electricity meters to save electricity bills, and has begun to try it out in the families of its employees

the problem needs to be solved

in view of its revolutionary role in the field of energy and its strong traction on economic development, smart electricity is no longer a problem in the world. However, at present, many links of smart electricity are basically in the conceptual stage, and some key technologies have not been completely solved. Therefore, for the United States alone, it will take at least 10 to 20 years to achieve the popularization of smart electricity, and it may take longer for other countries. The problems faced by the popularization of smart electricity are as follows:

investment mode. Smart electricity involves not only the transformation and upgrading of the original circuit network, but also the investment of new equipment. It is a costly and time-consuming project. In view of the huge capital required and the long return cycle, it is unlikely to be invested entirely by enterprises, and the unilateral investment by the government will also be restricted by financial funds, and even form a crowding out effect on private capital. Therefore, even in the United States, different cities also adopt different investment methods, some of which are fully invested by the government, and some of which introduce private capital. However, in either way, for some developing countries, the huge capital required by smart electricity will be a great pressure, and the globalization of smart electricity may also stop because of financial constraints

business model problems. Even if the investment problem is solved, how to adopt the business operation mode after the completion of smart electricity is also a thorny problem. In the United States, 80% of smart electricity is prepared to be owned and operated by the private sector, while the power supply enterprises in Boulder, from power generation, transmission to retail, are owned by the municipal government. As for other countries, whether to adopt unified operation owned by the government or mainly managed and operated by enterprises, or whether to operate jointly by the government and enterprises, it depends not only on the way of early investment, but also on the specific analysis of the market environment. Without a unified business operation mode, we can find a feasible operation mode through various demonstration projects and projects

unified standards. Smart electricity has the characteristics of globalization, so it should have a set of international standards. However, at present, there are many differences in the formulation of smart electricity standards in different countries, and smart electricity involves many electrical products and technologies, and the interests of suppliers. Different product suppliers will adopt different technologies and standards, and sometimes there will be different development directions and trends when selecting a certain product. Based on this, the smart electricity alliance of the United States is currently cooperating with 15 United Nations agencies and the international standards organization (ISO) to develop a set of smart electricity standards and interoperability principles. At the same time, China and the United States are also actively working together to develop an international smart electricity technology standard

key technical issues. At present, both electric technology and basic material technology can not fully meet the requirements of intelligent electricity, and even the safety of some technologies remains to be demonstrated. Unlike the United States, which uses high-temperature superconductors as the support of smart electricity, although the UHV transmission adopted by China can reduce the losses in the transmission process and reduce the conductor cost, due to the high voltage level and large current, this kind of electrode is vulnerable to strong adverse weather. According to a NASA report, if the solar storm that hit the earth in 1859 repeats, it may have a serious impact on the modern high-voltage transmission system. Most substations are likely to melt, and the whole power supply recovery time may be as long as 410 years
