Polaris solar PV net news: Internet programme as a global energy days after global energy low carbon programme for world cooperation to advance the climate change process, from a technical perspective provides a possible solution.
Energy Internet is the author of the third industrial revolution Jeremy ˙ Rivkin presented a new concept. In his design, the combination of Internet technology and Internet renewable energy, will power into energy-sharing networks from centralized fossil fuel use the shift to distributed renewable energy. Rivkin also on the possibility of sharing energy and intercontinental: “half of the Earth at night, extra energy can be shifted to the other side of the day the Internet intelligently. “When many people believe that Rifkin’s theory is impossible, CEC, State grid Corporation chairman Liu Zhenya, Director of the plan will be put into practice, who in a book published in February 2015, the energy of the Internet around the world, for a complete blueprint for global Internet concept of energy planning. He looked forward, ultra high pressure technology of the global Internet will rely on advanced energy and smart grid technology, forming connections equatorial region of the Arctic wind, solar power and State large renewable energy source bases and main load Center of transnational and Trans-World strong smart grid of interconnected ubiquitous, global interconnection pattern and plan to 2050.
China’s contribution to global efforts to combat climate change for the world’s clean energy solutions
According to the United Nations Panel on climate change (IPCC) released in 2014 of the fifth assessment report, if by 2100 global parts per million of carbon dioxide is about 450ppm or lower, is likely to stay below 2 degrees Celsius of temperature change in this century. This scenario 2050 global greenhouse gas emissions lower than the 2010 41%~72%,2100 annual emission level is close to zero or even lower. Energy systems there must be sweeping changes, a substantial increase in low-carbon energy supply. IPCC predicted that low-carbon energy as a percentage of primary energy in 2030 and 2050 to reach 24.5% and 60% respectively, more than 2,100 years or even up to 90%.
IPCC estimate of future emission reduction scenarios, but not emissions reduction technology path. Emission reduction by each country’s own ideas, Germany developed the 2050 energy-oriented programme, 2050 clearly Germany’s renewable energy goal is that 60% per cent of total energy consumption, total electricity consumption reached 80%. Countries of the world climate conference in Paris, by 2015 the negotiating process needs, preparing to release in the first half of States “national independent contribution” (INDCs).
Global energy of the Internet is a great plan, its great because it is not only China’s clean energy solutions, and offer the world a global integrated energy solutions to combat climate change. Study on the distribution and status of international energy resources a lot, have a regional solution, such as the Sahara solar energy deliveries to Europe across continents, but few of global sustainable energy solutions put forward. Ministry of industry and information technology, Department of industrial policy Director Feng Fei believes that the energy of the Internet is the first in the world. According to the book description, relies on global energy Internet, global around of wind, and solar, and marine can, can renewable energy can convenient to conveying to global around of various user, to 2050, clean energy accounted for once energy consumption total of 80% around, became led energy, at global energy carbon emissions only for 1990 of 50% around, can achieved global temperature liters control in 2 degrees Celsius within of target. Chinese Academy of Sciences, Tsinghua University Professor Lu Qiang believes it is “proposed by standing on the height of global and viable top-design”.
The UN climate summit in September 24, 2014, Vice Premier of the State Council, China’s Zhang gaoli as Special Envoy of the Chinese President stressed in his statement that “China, as a responsible country, will be bigger and better results on climate change, undertake international obligations.” For China, actively participating in global climate negotiations is an important platform for active participation in international governance. China’s obligation not only domestic emission reductions, but also with countries around the world co-sponsored by the global technology solutions to address climate change, and China’s powerful innovation of government administrative capacity, strong technical capabilities, a strong manufacturing sector expanded, building a global clean energy system.
Internet programme as a global energy days after global energy low carbon programme for world cooperation to advance the climate change process, from a technical perspective provides a possible solution. International governance is also a political and economic climate and the interaction of technology, the technical concept of China is of great significance, which guide all future emissions reduction provides a new concept for the current climate negotiations repeatedly stalled the transfer of low-carbon technologies to provide a new line of technical cooperation.
Global energy Internet’s significance lies not only long-distance transmission of clean power, it also stressed that “national pan-in smart-grid wind power, solar power and other friendly access to intermittent power supply, and power generation and energy-using equipment that is used, and with the Internet, Internet of things, intelligent mobile terminals integration.” This makes clean power generation, consumer credit and other information for side are widely collected, which will provide technical support on greenhouse gas accounting, to form the global standard of carbon reduction MRV (measurable, reportable and verifiable) provides a potential possibility. On the, distributed power and distributed storage can relies on energy Internet achieved has data integrated, it guarantees has distributed emission reduction project data of can collection sex and authenticity, greatly reduced has project nuclear card cost, makes distributed emission reduction project combination for CDM emission reduction project or China of CCER emission reduction project provides has technology possibilities, for prosperity carbon market and advance global carbon market of established provides has new of technology feasibility.
One goal of global energy Internet, two basic points
For the global Internet, its core goal is to deliver clean energy to lead. UHV techniques is an important technical innovation achievements of national grid in recent years, Liu Zhenya will be their contribution to the energy of the Internet concept envisaged by Rifkin’s energy planning blueprint on the Internet on a global scale. UHV transmission technology and energy together, these two technologies of Internet technology constitute the two basic points of global energy Internet, both indispensable to each other.
Without the energy Internet technologies, just using UHV technology for intercontinental network, could only be called ultra high voltage power grid in the world if ultra high voltage power grid transporting electricity generated electricity is a large coal-fired power plants, rather than the main conveyor wind solar and other clean energy, it has no relationship with RIVKIN said the energy Internet. Real Internet through the use of Internet technology to make renewable sources of energy become the dominant energy source. UHV regional energy around the world connected to the Internet, truly global renewable energy share, would have really formed a global energy Internet.
So you have to answer three questions: the first is a miniature of the Internet already accepted a larger percentage of renewable sources of energy; the second is ultra high voltage transmission technology to confirm the feasibility of mass transmission distance; the third is whether Internet technologies can help pressure wind solar mass transportation volatility.
Micro power supply the Internet is dominated by clean energy power systems
Rivkin envisaged energy information and communication technology of the Internet is decentralized and distributed renewable energy integration, dominate renewable energy systems. However, the electricity system to accept more volatility in a strong wind and PV is a very big challenge. In this connection, the exploration of Western European countries most progress. Denmark’s power structure, wind power has accounted for more than 30%. But Denmark, after all, just a land area of 43,000 square kilometers, population of just more than 5 million of the country. Germany as global GDP fourth power, leads the EU emissions reduction targets and actions, its exploration of new energy system even more worldwide attention. In 2011, Germany shut down all reactors before the Government announced the 2022, at the climate conference in Lima in December 2014, Germany announced a 56 closing some coal-fired power plants in the future to achieve by 2020 emission reduction target of 40%. Abandoned reduced coal in Germany rely on renewable energy sources to ensure energy supply? Germany’s efforts is indeed effective: renewable energy Germany electricity rate in 2010 is 16.4%, 2014 has reached about 25%, is expected to rise to 35% by 2020. Germany is creating a new system has the potential to lead the world’s energy system.
Germany hopes through technical innovation to meet the needs of distributed energy supply in the future. Germany Federal Ministry of Economics and technology and the Ministry of the environment was launched in 2008 on the basis of smart grid plans to promote technological innovation called E-Energy, and put forward the goal of building a new energy network. E-Energy characterized by a structure of distributed energy supply to meet the future demand of electric power system, taking full advantage of information and communication technologies to develop new solutions in the entire energy supply system to achieve integrated digital control and monitoring the Internet and computer, and finally achieved status is “to electricity production consumption”, maximizing the use of wind power and photovoltaic.
It will carry out infrastructure and communications and coordination between the electrical, for example, when particularly strong wind, and excess electricity will, it is cheaper, consumers will be able to open the appliance in due course, such as refrigerators, washing machines, dishwashers. Electric power system of two-way interaction is particularly rich, owners can provide car orders, charge the battery at the lowest cost, or just “green electricity” to charge the battery. E-Energy system can even absorb surplus electricity from batteries and fed back into the grid, when electricity demand peaks provide additional. When entering the load at its peak, the cycle of ICT gateway to coordinate small cogeneration plants, or storage systems supplies. E-Energy may form a new electronic energy markets, customers themselves can be used as small power suppliers (for example via solar panels) to play a more active role. This brand new service appears in the market, such as “delayed connecting time allowed” and “returning power back to the grid at peak electricity demand,” “used only in strong sunlight or strong wind” and so on. In the market, energy producers and consumers to promote a safe, cost-effective and environmentally friendly supply of electricity to be rewarded.
Germany’s E-Energy plans now being six areas, each area has different energy Internet theme. RegMod projects like the Harz region, Harz in Germany Middle mountainous region, rich in renewable energy resources such as wind and hydro. RegMod Internet project is a comprehensive energy project, its core model integrated energy storage facility, electric cars, renewable energy and smart appliances, virtual power plant. Dāng can renewable energy power has surplus of when, pumping storage station and EV can store extra of power, smart household appliances, like smart washing machine, and smart wash Bowl machine, and smart water heater,, also will timely opened consumption extra power; in power needs climbed of when, these storage can facilities can and smart with electrical together constitute virtual station, through release by storage of power and reduced smart electrical of electricity volume to meet tension of power consumption needs. RegMod project contains a lot of energy Internet elements, including renewable energy, smart appliances, electric vehicle, distributed energy storage facility, is the prototype of the energy Internet.
Long distance power transmission capability of UHV technology being tested
Energy now on Internet technology have been able to achieve small power systems to accommodate a higher proportion of renewable energy in the region, however, long distance power transmission is still necessary. Load centers like Beijing, even solar photovoltaic panels on roofs are all, it is far from achieving energy independence, must be transferred from the field a lot of electricity, and Xinjiang Autonomous Region and Mongolia’s wind and solar energy resources are unable to digest the local and need to go into load Center power delivery and other places in North China. UHV technology in distributed energy still needs long distance power transmission.
On January 27, 2014, Hami Zhengzhou ± 800,000 South-kilovolt HVDC project officially put into operation, which is now the world’s largest DC transmission project, and is also the longest transmission distance of the national power grid construction of UHV projects. Line beginning in southern Hami, Xinjiang energy base, the location of Zhengzhou, the line is 2,210-kilometer. The project is the implementation of “electronic delivery of Xinjiang” strategy’s first UHV power transmission project. According to public data is reported in Xinjiang in 2014 to deliver electricity 17.5 billion-kilowatt kWh, which Zheng direct current UHV is the major transmission channel (in addition to 750,000 volts transmission channel on the Northwest power grid). It is understood that when Xinjiang plans to deliver electricity in 2015 35.9 billion-kilowatt, more than double by 2014. Hā zhèng tè high-pressure delivery charge when coming up to a maximum of 50 billion-kilowatt. Hā zhèng tè pressure technology has shown that 2000~3000 km of distance of transmission is feasible in technology and cost. Hā zhèng tè high voltage in the admission of wind turbine electro-optical excellence, 2014 Xinjiang power photoelectric reached 2.243 billion kWh of electric power delivery stroke, representing all of Xinjiang sent about 17%. Former Minister of electric power Shi dazhen believes, “built of sgcc accumulated ‘ three straight four ‘ UHV transmission engineering, comprehensive verification of possibility of ultra high voltage transmission, advanced, security, economy and environmental friendliness.”
Serious haze background coincided with governance in North China, UHV construction accelerated sharply. June 2014, the National Energy Board on accelerating action plan for air pollution prevention and control, issued by 12 major transmission channel construction included in article 9 of the notice of UHV projects, including national grid 8 UHV engineering, as well as the southern power grid Corporation 1 EHV projects. That same month, XI, General Secretary of the central financial and economic leading group of the sixth meeting of the energy revolution, explicitly “developing UHV large-scale long-distance transmission technologies.”
By 2015, UHV and become “along the way” strategy of strategically important technology. In 2015 will proceed with the construction of China State grid, UHV transmission channel to five Central Asian countries, Russia, and Mongolia to China’s special high-voltage LU support “along the way” strategy. Russia yerkovtsy ± 800,000 volts-Hebei bazhou HVDC project and so many lines starting in 2015 in the pre-development, of which Kazakhstan Ekibastuz-Nanyang ± 1.1 million kilovolt HVDC project, a distance of approximately 3000 duō qiān mǐ, will become the world’s longest high-voltage transmission distance road. These projects show that ultra high voltage long distance transmission of the technical feasibility and economic viability, as well as the prospects for large-scale development.
Ultra high voltage for supplying clean energy of the future
Current UHV projects’ve show Interstate power transmission capacity. But Rivkin intercontinental grid is envisaged transport renewable energy, while current UHV is to transport coal, wind power as a supplement. 2014-scenery in Xinjiang power delivery, and only 17%, is mainly transported energy base in Hami coal for power. Long-distance transmission of electricity from coal whilst protection of energy supply to the North, help to alleviate the smog problem in North China, but the amount of pollutants and reduced, but differences in North China or Xinjiang emissions. Currently planned international UHV projects, yerkovtsy ± 800,000 volts-Hebei bazhou HVDC project sending end power supply main is Russia Amur Erkov Qi power plants burning lignite, Kazakhstan Ekibastuz-Nanyang ± 1.1 million volts high voltage DC supply power is coal-fired power project.
In the long-term planning of global energy Internet, using UHV in China from Kazakhstan and other Central Asian countries entering should be solar and wind power, from Russia far East input and end with hydropower and wind power of the Arctic. To get ultra-high voltage long-distance transmission for wind solar, you need to rely on Internet technology supporting demand-side response of long distance and large capacity. At this time, the ultra high voltage power grid is not only energy carrier, but “with the Internet, Internet of things, intelligent mobile terminals integration, China’s energy future Internet platforms to achieve large-scale exploitation and utilization of clean energy.”
Energy Internet able to achieve demand-side response of long distance and large capacity
Energy Web’s core purpose is to use Internet technology, promote energy electric power systems at the core of various types of equipment in the network information exchange to achieve balance between energy production and consumption in real time. Wide area coordination and mass-distributed device Plug-and-play interactive distributed energy storage can be achieved in the future, to provide long distance and large capacity of demand side response capacity. Electric vehicle energy storage, home storage, buildings, natural gas power generation and electric switch technology will play an active role.
Huge amounts of distributed energy system of intelligent home devices. In the energy Internet, household refrigerators, air conditioners, home energy storage devices that elephant formed a large, distributed intelligent home energy control system. Just think, if Beijing millions of families of refrigerator and air conditioner in an active or passive manner into the electric power dispatching system, which posed the demand side response capacity is amazing.
Huge formation of electric distributed energy storage system. Transportation is another fossil fuel, except the power consumption. In 2010, the final energy use accounted for 27% of the transportation sector. Transportation industry’s largest emission reduction potentials will be electric as the core of electrified transportation system. Can be used as a backup power supply for electric vehicles and mobile storage, electricity charge less busy periods, in peak electricity feeding into the grid. When millions of distributed energy storage system composed of thousands of electric vehicles and electric power systems are highly integrated, will not only enable them to minimize the impact on the power grid, and can form a huge virtual power plant, with strong demand response capacity.
Gas coupled to form a powerful network and power grid load capacity. The proportion of natural gas in the electric power system is rapidly rising. United States in 2013, following the announcement of carbon emission standards for new plants, new power plants are gas-fired power plants. Gas-fired power plant with good peak function, in particular small and medium-power gas turbine unit. Recent power switch technology was interesting, it can be produced by water electrolysis hydrogen and oxygen, then mix hydrogen with carbon dioxide to produce methane. Electric switch gas conversion efficiency of 60%~70%, Germany currently is carrying out a business model. Power switch technology will convert the excess output of renewable methane, can be injected directly into the transport and storage of natural gas networks, which makes future power systems and energy flows between gas networks from one-way to two-way. Widely exists in generation side and user side of a small gas-fired power generation and electricity-gas facilities, will form a powerful distributed energy storage system.
Large-scale, distributed energy storage equipment to be run efficiently in the global energy Internet, dynamic pricing is the most indispensable support system and the global power market. Peak-Valley electricity price difference that is large enough to attract investors and ordinary families actively into the electricity market. Relying on advanced Internet technology, consumers according to real-time pricing automatically adjusts power consumption and energy storage device is running. Prime Minister Li keqiang in 2015, the Government proposes to develop “Internet +” action plan. “Internet + energy revolution”, can be understood as energy Internet. New electric power system reform plan by 2015, should incorporate substantive “form the market decides price mechanism” and “build electricity market system” to implement Prime Minister Li keqiang “+ Internet” action plan for promoting the construction of China’s energy Internet, promote world energy revolution.
