Energy Internet has recenε¥♦∑tly been "very hoΩ ≤¶t" in the energy circle, with tγ→he concept of "Internet +&quo±∑↕t;, the traditional energy industry ☆€​±seems to have ushered in a wave of inno¶®γ≥vative thinking. Also  ★in the context of the energ∑€y revolution, we must open up a new★ > way to change the modφεe of energy development, a✘λ¶nd the prospects of this roaφ&d in the end how? More attention h¶'as been drawn to the industry and ε↑outside.

　　"The energy Internet is a highβ¥₩ degree of integration of multiple ty★ pes of energy networks and transport ‌™£§networks" "≠Ωδ♠;The basic concept of the energy I"₹nternet and smart grid is the •β★same, and the content can not be fo₽₩ und in principle different&♦ quot; "The ener​ §gy Internet is The ene←δ&'rgy Internet is a strong smart grid w☆✔πith ultra-high voltage ↓♣grid as the backbone (channel), with >•‌clean energy transmiss✔γion as the leading, glo♣σ​σbal interconnection and≠©☆↔ ubiquitous," various understandi•↑&®ngs and interpretations of the∏>® energy Internet have appear£←ed, and people are not sure wh♠>at to think about it.

　　Energy Internet concept was born t∏ ®'en years ago

　　From 22 to 24 April™↕¶β, at the foot of Fragrantγ✔≥‌ Hill in Beijing, a number of academici€§§↕ans and more than 50 experts an★ ↕←d scholars participated in an <σacademic conference o♣≥n the theme of energy Internet. Confer×Ω÷£ence parties on the concept and structγ±✔→ure of the energy Internet, en> ≤ergy Internet operation mechanism ∞∑‍and market model and other to♦≤™®pics for in-depth discussion, whi✔↑☆ch is so far China&#‍ ÷39;s academic community for the eγ✔"≠nergy Internet at the highe"★st level of a semina$€↓₩r meeting.

　　When did the concept of energy∏✔ Internet come into being? Cao Junwei,φ♦ a researcher at Tsinghua α≤ University's Institu♣><↓te of Information Technology, who ha ♦≤☆s long been engaged in cross-®✔disciplinary research o♦≤"n information and energy and power↓← technologies, believes that in 200✘✘π4, The Economist magazine published an£∞ article called "buildingthΩ‍eenergyinternet", whi←‍ch is the earliest literatur'♣e to formally put forward thiγ®©&s viewpoint.

　　In 2008, Thomas Fried∑γ‌man, a famous American journ'☆alist and winner of three Pulitzer '₹∞Prizes for journalism, introduced the ✔&✘energy internet in his m☆ε‌λonograph "The World is Hot‍∑¶, Flat and Crowded", which is ☆✘ 'also the initial expl∑φ<oration of the energy internet at the ≠♦•↕economics level.

　　Explorations at the technicalΩ®  level also took place around 2008, ↕ when Germany put forwardβλ♦≤ the E-ENERGY programme, with an inα§vestment of about 140 millionσ∞₹ euros, to make full use of  >information and communica‌←tion technologies to solve the new prβ•oblems faced by the future≤§→♣ power system dominated by ≥φ>>distributed energy supply, w÷‌< ith the aim of creatiφ÷↓§ng a brand new energy Internet ♦₹from the distribution network to the ciσ∞‍rculating power grid.

　　In 2009, in the U.S. city  &✔of Dubuque, IBM and the govεΩ←ernment began to bui→€ld the first smart city with an inte∏αlligent energy network,¥φ&£ in order to create a connectio♣&σn between all the resou≈εrces of the city, inc®©<luding water, electricity,$'← oil, gas, transport,₽→ public services and so on.

　　The energy Internet has attr噣‌acted widespread attention in the count€φ±ry, probably more because of ₽♣↕Rifkin's book "The Thi₩≤Ωrd Industrial Revolution", wh∞₹≤↓ich imagines that "i♣ n the upcoming era, we ‍÷φ₽will need to create an 'energy In÷®ternet', so that hundreds of mill​∏Ω ions of people can produce green renew☆÷able energy in their homes, offi©σces and factories". green renew δable energy."

　　The concept became more widely₹₹←​ known when Liu Zhenya, Chairman ♠®of State Grid Corporation₹☆₽♦, put forward the idea of "buildin♥≤‌g a global energy internet to serve‌≈ the sustainable development of ↕÷human society" at an academi §‍σc conference in Washington, ₹↓€D.C., in 2014.

　　Different Perspecti<↓ε ves on the Energy Intσφ₽ ernet

　　Liu Zhenya proposed in his bo∑'✘&ok "Global Energy↕‍ Internet" that the g∞©lobal energy Internet ≈∑is composed of transcontinental and tra₹ λnsnational backbone grβ£"ids and power grids σ₹♣of various voltage levels in various c☆φ₽≈ountries, connecting "one p§₹ole and one road" (the Arcti∏ §♦c and the Equator) with large ene​₽←rgy bases, adapting to the needs of a®±ccessing various distributed↑" power sources, and being able to trans÷♠mit renewable energy s£•¶ources such as wind e¥±nergy, solar energy and ®±"≤ocean energy to various ¥$types of users, as well as pro¥"₽σviding a service for the su€&§§stainable development of hδ×uman society. It can transmit rπ≈  enewable energy such →÷as wind energy, solar energy and ocean ₹↓energy to various types of u↓γ☆♦sers, and is a global energy alloca♣£εtion platform with a w€‌'≈ide range of services, strong configur→♠×​ation capability, high safety and re¥✘liability, and green an♠φ₹d low-carbon.

　　"The energy Internet in my§≈→ mind is a comprehensive ↔&σ×energy network composed of physica×γl systems, namely the power grid, gas♥'¥ network, heat network, transport n♣γπ↔etwork, etc." Xue Yusheng,←™ academician of the ₹≈"Chinese Academy of Engineering and∏✘ honorary president of the State♠☆↑π Grid Electric Power A✘¶‌★cademy, also offered his views.

　　Professor Yu Zitao, director of tφ♥he Institute of Thermal Engineer↕♠βing and Power Systems at Zhejiang✘π University, believes that the develop↑₩♦ment of a high-efficiency energy n'×±σetwork will take the route of high-♠αefficiency gradient utilisation, in♣‌ > which the energy of systems that c↔'®an independently output electricit♠★​✔y, heat and cold wil✘δ‍≈l be used in a gradient♣✘$ manner, so that the comprehensi•$ve utilisation rate will reac•>αδh more than 90%.

　　Academician Yu Yixin, on the othe&♥r hand, said that the basi♥"§≥c concepts of the energδ≠>♠y Internet and the smart gridλβ that we have already dis÷βcussed are the same, and the contπ‍★δent can not be found to be different ®£'in principle, including intelligen$•‍←t universal transformers such as elecε×'₽trical energy routers.

　　"Due to the differentαΩ perspectives that everyone stands on,₩← different understandings and vie$₽ws are generated, but§₹↓→ from the academic level, it is not ₩$ possible to distinguish≈™ who is right and who is wr↕​∏ong, because the work can be Ω✔"&carried out from different level♣÷s." Cao Junwei ♦δ told reporters that the development a£®φ nd construction of t®Ω≤he energy Internet is a complex syste★< matic project, which needs to start froγ☆m the system architect‍$↓♥ure, technology research and develo☆​δpment, standards develo‌ pment, policy design and other a∏±spects and links, and the ≥γ&way should be to take the road • of hierarchical grading, from small s"₩cale to large scale, from®>÷> simple to complex, from expe≈∑≈Ωrimental to demonstra→®↔tion, and then to the maturi₽→ty of the promotion.

　　SmartGrid or SmarterGrid

　　Although there are a lot of v​λiews on the energy Internet, ∑≤↓ there is an obvious common₩  ¶ point is that the smart grid will play∑φ an important role in building the en✘★ergy Internet, so under®≈≤standing the content oλφ₹f the smart grid is crucial to ​♥© understanding the energy Internet.

　　In fact, the indust↓δ₽ ry and outside the concept of smart gr •‌id understanding has∞≥  long existed different vie♣↑'ws, whether it is sm∞∞©artgrid or smartergr ♣βid (smarter grid), peo☆φ ple have their own viewsλ$.

　　"The essence ♠¥of the smart grid should be optimisσ&ation. The future of the grid, we ↔&÷φcan not rely mainly o© n people scheduling, must ​ be through information te§∑↓chnology and computer science for ♥ πautomatic regulation and control"γ→, to achieve the whole pσ ↑≥ower system completely™& closed loop. For exa✘§♣÷mple, the current scheλ♦≠ duling in Shanghai, has®↔γ been initially done." Lu Q₹&λ$iang, an academician of the Chine₽≈♦→se Academy of Sciences and a profe₩&ssor at Tsinghua University, pu☆×σt forward the concept of≈≤​ smart grid with hybrid cybernetic♦←s, arguing that the entr♥λy of communication and mathemδ♦atics into the classical  ​≥power system gave rise to the third ind$'ustrial revolution of the power syst ↑em, which gave rise  ★to the smart power system.

　　"By 2020 the State Grid≈≤∏∞ Corporation will have fully built a ‌☆↓★unified 'strong smart grid​∞9; with technology and eq ∑αuipment fully reaching the   ★international advanc♣¶✘γed level." According to Shu Yinb↓✘iao, general manager of the S✘↓£βtate Grid Corporation, China'↔¶s smart grid includes s♠'γγix links in the power system, namely poα¶≈wer generation, transmissi↔≤©on, substation, distribution, power c<☆onsumption and dispa∑£"tching, and is characterised b∏ ♥y the "smart" technologi≥<es of informatisation, digitisation✔✔, automation and interactionγ≥. China's smart grid is₩•₽ first of all a strong p‍Ωower grid, in which, with a loδ™ng distance, large capacity tr∑&ansmission characteristi₽¶cs of the ultra-high voltage grid ¥ε$will become the core link, which is de ♦βtermined by the stage of China's ≈​economic development,✘™¥× the centralised distribution of energ•♥y characteristics.

　　"Smart grid is a development gσ$oal." Academician of the Chinese♥$ Academy of Engineering, th>"₩e Southern Power Gridδ> Corporation Expert Committee Directo‌∑↑‍r Li Li Li, said in an i™'σnterview with reporters, the developmen←​t of energy and electricity±↕∞☆ have 3 laws to follow★✔™, including the law of science a☆≠nd technology develoα✔pment, the law of social↔ ​ development and the law of market deveββ§lopment.

　　China's famous power<ε system analysis, planning and si↔← mulation experts, acad‌₩↕≈emician of the Chinese Academy o↔↓f Engineering Yu Yixi‍¥£✘n believes that the smart grid wil•γ♣ l change the way people livδ≥♥e and work like the Internet, t 'he realization of the smart≈δ≠ grid requires a long≥δ transition, sustained res>'©earch and development and aλ↔ variety of technologies for long-ter↓≈✔ m coexistence.

　　What is certain is that i↑¶≤>n the context of the third industrial r∑↕€evolution, the integration of power✘σ± grid and information te±∏¶chnology is an inevitable £÷trend, whether we focus₹ ±Ω on the current smartergrid or φ™our ideal smartgrid, to₹ ​ create a highly efficient g≤₩"rid will be the core contε"ent of the energy Internet.

　　The impact of Internet thi±↓nking on energy

　　Energy is a tradit‍↕€ional industry, the In §φternet is an emerging industry, theεδ↔ integration of the two will certai•• ∞nly bring the concept of collision, ‌ ♦¶the concept of change may <λ™←be the beginning of t≤¥echnical and institutional change§π₽£.

　　"The traditional po±<₩εwer industry by the natural mon​÷  opoly characteristics and security≈¥♣‍ constraints, the sensitivity >→of information technology is not enoug↔§×•h." Li Li Li academi₹§cian interviewed by a report♦×er expressed such a view.

　　"If the grid in☆÷✘✔telligent or in the trφε£ aditional grid architecture thr≥★ough information technol↕πγogy and intelligent means,€₹ to solve the problem of equipme©'nt utilisation, security and reliabi♦>λlity, power quality and renewable en∏↓¶ergy access, the fundamental differφφ£'ence between the energy Internet is theΩφ   use of Internet concepts, methods a↓σnd technologies to achieve a major ∏©​↓change in the energy <£₹¶infrastructure architecture itself,•$∏ making the energy of open♦✘≤✔ interconnection and exch★£ ange Sharing can be as convenient as←↕₹ sharing information on the Internet.&q↕♦uot; Cao Junwei said.

　　Openness, interconnection, reciprociδ"ty and sharing are the characteristiασcs of Internet thinking, while the tra↓♠←ditional energy industry plac↓♠‍es more emphasis on production, pro↕¥‍fessionalism and security. A number ₽ε↕εof experts believe that the developm≈$ent of distributed eσ σnergy has given the energy industr∞∏♣Ωy an opportunity to transform, <™$βwith the traditional✔↓✔∑ power industry emphasises the devel®₹ &opment mode of gener ¶ation, transmission, distributio<∞₽n and transformation, ☆λ®distributed energy makes th "₩e energy flow, power flow change>ε≥s, the operation of the local mi§✔&crogrid needs to be open,€↑≥≥ sharing and other concepts embedded±‍± in the energy and po$☆ ♣wer industry needs to face.

　　The Internet is invisible and bor₩γderless, and the dev∏↑♦₹elopment of energy Internet will ♣±¶also be open and ceilingless, ₩ only a large amount of in∑∑novation and practice will bring abλ♣∞→out a brand new energy industry.
