Smart electricity: moving forward in the game

Canadian mark kerbel never thought that an idea he accidentally had was bringing about, or even revolutionary, social development in the information age

usually, there are all kinds of power consumption devices in an office building, but how to reduce the overall power consumption is not a challenging job for Campbell, an environmentalist

the initial motivation is actually very simple, that is, to coordinate the electrical appliances in the building and reduce the power consumption of the building during the peak period. But to complete this work, we must also have a control system, of course, not a very troublesome one

in the winter of 2005, Campbell invented a wireless controller, which is connected with various electrical appliances in the building. Campbell proved that these electrical appliances have been effectively controlled

Campbell later publicly explained this process. For example, an air conditioner operated for 15 minutes to maintain the indoor temperature at 24 ℃; The other two air conditioners may be shut down for 15 minutes on the premise of ensuring the indoor temperature. In this way, without sacrificing each individual, the energy-saving goal of the whole building can be achieved, because the adjustment of each electrical appliance is automatically completed

now this mode is usually called intelligent system. Campbell's equipment is very simple, without human management or training. It can be put into use after spending a few small clothes, but it performs very well in synergy

therefore, Campbell said goodbye to the place where he used to work and set up a small company. At present, Campbell has customers in Canada, namely Toronto hydro. Now, he is trying to enter California, and this small company has appeared more and more frequently in major media. Many places, such as hotels, hospitals and factories, can save up to 30% of peak power after using this wireless controller

Campbell's technology is actually a popular kind of smart electricity at present, and the technology around this concept is emerging constantly. On February 17 last year, U.S. President Barack Obama signed an economic stimulus plan of up to $787billion, of which $120billion was used for infrastructure, while the large-scale construction of smart electricity was listed. Obama also took it as an important part of the national energy strategy

opinions of all parties

in fact, smart electricity is not a new concept. The United States has put forward it as early as 2001. The government has paid attention to it since the August 13 power outage in the United States, and it has become the national concept of the United States since 2009. Huang Qili, academician of the Chinese Academy of engineering and honorary chief engineer of northeast electric power company, said in an interview with China business news

according to Huang Qili, China began to make a lot of preparations in 2006, because with the needs of development, electricity also needs a lot of digitalization and informatization. The word I use is intelligent power system, not just a concept

however, so far, no one has given an accurate definition of smart electricity. It is like a complicated story, which has pushed up the rise of smart electricity concept stocks again and again

public information records the understanding of multinational giants on smart electricity

Ge believes that smart electricity is a collection of power and communication architectures, and integrates automation and information technology structures into our existing power network. In essence, smart electricity is to improve and modernize the power network of the 20th century for the society in the 21st century

compared with the view of General Electric, Cisco seems to extend its concept to a higher level: smart electricity is an intelligent future power system, which connects all components such as power supply, power network and power demand through intelligent communication system, and brings huge benefits to power supply units and power consumers

at the end of 2006, Time magazine of the United States awarded you the person of the year in 2006, representing thousands of individuals and heralding the advent of the era of personalized consumption

based on this, IBM calls smart electricity electricity electricity 2.0. It believes that compared with traditional electricity, smart electricity looks more like Internet, which can access a large number of distributed clean energy, such as wind and solar energy, integrate and utilize various information of electricity, conduct in-depth analysis and optimization, and have a more complete and in-depth insight into electricity, To realize the material and design of the inner surface of the fixture in the whole intelligent electric ecosystem, we should make a good real-time decision when the sample reaches the maximum load

based on this 2.0 model, IBM has outlined a beautiful blueprint: for power users, they can choose and decide more effective ways to use electricity; For power companies, they can decide how to better manage power and balance load; For the government and society, we can decide how to protect our environment. Finally, improve the efficiency, reliability and flexibility of the whole electrical system to achieve a higher degree of intelligence

in 2008, Americans showed a beautiful scene of smart electricity in Boulder, Colorado. Every family installed smart meters, so that people can intuitively understand the electricity price at each time, so as to arrange some things that need to use high-power appliances, such as washing, ironing, electric heating, etc. in the period of low electricity price

some experts also analyzed that the development of smart electricity in the United States focuses on the distribution and consumption side, paying more attention to the innovation of business models and the improvement of user services, and promoting technological innovation, Stimulating the economy and clearly stipulated in the national military standard gjb150.1-86 general principles of environmental experimental methods for military equipment "The temperature of the measurement system near the experimental sample should be within ± 2 ℃ of the experimental temperature for employment.

at present, the development of smart electricity in the United States is mainly based on enterprises, which independently formulate development goals and technical routes according to their respective needs. The boulder smart electricity city project is currently in the current stage of the project, and it was officially implemented in the second half of 2009. The Miami smart energy project is still in the research and design stage.

China has broken through the country of

The plan of electric power is to make breakthroughs in the construction of five pilot projects, including intelligent power dispatching technical support system, intelligent substation, electric vehicle charging facilities, power consumption information acquisition system and multi integration, in the specific construction and deployment of intelligent power in 2010

2. In terms of use performance, caiguoxiong, deputy chief engineer of the Chinese Academy of electric power, also said in an interview that electricity is a very important part of China's energy. Now we are engaged in a low-carbon economy. Sun and wind energy are promising energy sources, but how to use these energy sources effectively is a big topic for us: how to make comprehensive use of these energy sources. Therefore, the power industry should change the routine of the power system to make the power system more stable, safer and more energy-saving. Caiguoxiong said

this is also roughly the same as GE Xubo, chief engineer of the National Energy Research Institute. Ge Xubo also said in an interview that fields such as charging facilities, wind and solar energy storage, as well as advanced dispatching systems for electricity, including smart meters in the future, have been promoting

Su Shengxin, member of the CPPCC National Committee and general manager of Xinjiang electric power company, said in the proposal of the two sessions this year that the development of new energy is an inevitable requirement of China's energy development

Su Shengxin believes that China's primary energy is mainly coal, the proportion of clean energy is low, and structural contradictions are prominent. By 2020, according to the goal that non petrochemical energy accounts for about 15% of primary energy consumption and carbon dioxide emissions per unit of GDP will be reduced by 40% - 45% compared with 2005, the installed capacity of clean energy needs to reach 570 million KW

therefore, it is also incumbent on smart electricity to solve the problem of new energy. Previously, State Grid Corporation of China has determined the general plan of smart electricity. Ge Zhengxiang, director of State Grid Research Office, told this newspaper that smart electricity has established the principle of three steps

according to the national power planning, the first period is from 2009 to 2010. This stage is called the planning pilot stage, which focuses on the development planning of strong smart power, the formulation of technical and management standards, the research and development of key technologies and equipment, and the pilot work of all links

from 2011 to 2015 is the stage of comprehensive construction, accelerating the construction of ultra-high dead corner piezoelectric and urban and rural power distribution to eliminate accumulated plastic, initially forming a smart power operation control and interactive service system, and achieving major breakthroughs and wide applications in key technologies and equipment

2016 ~ 2020 is the leading and upgrading stage, and a unified strong smart electricity will be built in an all-round way, and the technology and equipment will fully reach the international advanced level

according to this description, by then, the ability to optimize the allocation of resources will be greatly improved, the installed proportion of clean energy will reach 35%, distributed power generation will realize plug and play, and smart meters will be widely used

according to the explanation of power experts, smart electricity is self-healing electricity first. According to the scientific explanation, self-healing refers to isolating the problematic components in the electricity from the system, and quickly restoring the system to the normal operation state with little or no human intervention, so as to provide power supply services to users almost without interruption

this impact is of far-reaching significance for the power system. In the past, many power outages were caused by power supply line failures or power supply facilities accidents, and smart electricity is trying to solve this problem

the National Energy Research Institute also believes that an important feature of smart electricity is that it can achieve two-way interaction between electricity and power users through innovative marketing strategies, guide users to actively participate in market competition, and achieve effective demand side response

in short, users can set parameters for various electrical equipment according to their own electricity habits, electricity price level and electricity environment. Intelligent electrical equipment such as air conditioning and lighting can automatically optimize its power consumption mode according to relevant parameters, in order to achieve the best power consumption effect, and then improve the power utilization efficiency of the equipment, realize power saving, and achieve the purpose of reducing electricity expenditure by selecting the power consumption time

it is estimated that the construction of strong smart electricity in 2020 will guide users to use electricity scientifically and reasonably, save about 156.7 billion kwh of electricity, and correspondingly reduce carbon dioxide emissions by 144 million tons. The National Energy Research Institute released a report

problems to be solved

the construction of natural and intelligent electricity, on the one hand, can promote the large-scale development of clean energy such as wind energy and the rapid development of electric vehicles, and realize the replacement of fossil energy; On the other hand, it can improve the energy efficiency of power generation, transmission, power consumption and other links and reduce energy consumption

the National Energy Research Institute has also made a calculation that the carbon dioxide emission reduction achieved by the construction of strong smart electricity will exceed 1.68 billion tons in 2020, which is equivalent to the carbon sequestration of 10million hectares of forest land in a year. If China's carbon dioxide emission intensity in 2020 is 40% - 45% lower than that in 2005, it is necessary to reduce carbon dioxide emissions by 6.9 billion ~ 7.8 billion tons

therefore, the National Energy Research Institute conservatively estimates that the contribution rate of the construction of smart electricity to China's achievement of the 2020 carbon emission reduction target will exceed 21%

however, at present, this is still a good wish. Wu Jingru, a senior domestic power expert, believes that smart electricity is a long-term project, and I'm afraid it will be carried out by the end of this century or even the next century. Now it's only the initial stage, so we can't rush
