Since China launched the “Discussing the Global Energy Internet†initiative in 2015, the development of the global energy internet has made important progress. More than 140 countries around the world have issued corresponding energy development policies. The “Global Energy Internet China Initiative†is used to promote sustainable human development. The global strategy has become a consensus among countries. In the future, China will further promote the construction of domestic energy Internet, promote and promote the concept of global energy internet in the world, and accelerate the construction of energy Internet demonstration projects.
"Economic Daily" reporter learned from the 2017 Global Energy Internet High-End Forum recently held that after years of efforts, China and Russia, Mongolia, Vietnam, Laos, Myanmar and other neighboring countries have achieved some of the power interconnection, interconnected scale of about 260 million kilowatts, The construction of oil and gas channels on the three continents of the northwest, northeast, and southwest is basically a sign that the global energy internet has entered a new stage of joint action.
"Friendship Circle" is gradually expanding
Faced with the challenges of resource constraints, environmental pollution, and climate change facing the world's energy development, on September 26, 2015, China issued an "Exploration to Build a Global Energy Internet" initiative. In March 2016, the Global Energy Internet Development Cooperation Organization was established and became the first energy international organization initiated by China.
In the past two years, the development of the global energy internet has made important progress. “Over 140 countries around the world have introduced energy development policies. The Global Energy Internet China Initiative as a global strategy to promote sustainable human development has become a consensus among all countries in terms of promoting development, strengthening grid interconnection, and increasing the level of power generation.†Chairman of the Global Energy Internet Development Cooperation Organization, Liu Zhenya, chairman of the China Electricity Council, said.
Over the past two years, relevant planning research has been steadily advancing. More than 100 research projects were conducted in depth and a standard planning system was prepared. Including the evaluation and calculation of global wind energy and solar energy resources; drawing the first global backbone network wiring diagram; clarifying the overall pattern and key tasks of grid interconnection on all continents; releasing the global energy internet white paper, realizing the theory and planning The important breakthrough.
In the past two years, international cooperation has been fully carried out. China has established good cooperative relations with more than 150 governments, enterprises, organizations, and research institutions in 47 countries and regions. A number of cooperation agreements, memoranda and joint declarations have been signed with the AU and the International Hydropower Association. In the grid interconnection planning, clean energy development, networking process construction and other fields to carry out all-round cooperation. The “interest circle†of the global energy internet continues to expand, and the high-end, pragmatic, and diversified international cooperation pattern is accelerating.
In the past two years, cooperative organizations have accelerated their development. The number of members has increased to over 300 in more than 40 countries and regions. Initially formed a global network system, strengthened institutional development, established the Economic Basic Research Institute, set up advisory advisory committees and technical academic committees, and launched cross-sectoral cross-industry cooperation. The level of research strength has greatly increased, and the cooperative organization has continuously grown and become an important force in promoting the transformation and transformation of the world's energy.
Construction conditions already available
“Building a global energy internet is an unprecedented global cooperation in the energy field. This is an innovation in itself. It is facing new areas, new topics and new challenges. Only relying on innovation can promote development and solve problems.†In Liu Zhenya’s view, The conditions for building a global energy Internet are already in place.
From the perspective of resources, the theoretical development potential of global hydropower, onshore wind power, and solar energy exceeds 10 billion kilowatts, 1 trillion kilowatts, and 100 trillion kilowatts, respectively, and the development of the world's energy needs can be met only at a rate of five ten thousandths. UHV power transmission technology is advanced and mature. Clean energy power generation technology continues to advance and smart grid technology is widely used. From an economic point of view, the cost of wind power and photovoltaic power generation has dropped by 30% and 75% in the past five years, and will continue to decline rapidly. By 2025, new energy competitiveness will exceed fossil energy in an all-round way. In terms of market demand, global electricity demand is expected to increase from 24 trillion kWh to 73 trillion kWh from 2016 to 2050 with an average annual increase of 3.1%. More than 20% require cross-border transcontinental deployment.
"It should be said that the proposed construction plan is not based on the air, but on the basis of existing research on technology, economy, etc. In fact, after two years of work, we have more confidence." Global Energy Internet Development Cooperation Zhang Yibin, deputy director of the Organization Development Bureau, said that from the external environment, the consensus on building a global energy Internet has gradually deepened; from the point of view of cooperation, it has changed from unilateral actions in China to multinational coordinated actions.
In recent years, the construction of China's energy Internet has become an important demonstration of the global energy Internet construction. For example, China’s UHV-built UHV line has a length of 35,000 kilometers, substation capacity includes a capacity of 360 million kilovolt-amps, and annual transmission of electricity exceeds 400 billion kilowatt-hours, making it a major channel for inter-provincial and inter-regional energy transmission in China. The atmosphere and environmental governance have played an important role. In addition, our country has already taken the lead in the world in smart grid construction and clean energy installation.
Steadily promote domestic construction
The construction of a global energy internet is a major system project that will affect the future of mankind. Undoubtedly, it will also face many problems and challenges. "First, it is still a question of ideological concepts." Zhou Dadi, former director of the Energy Research Institute of the National Development and Reform Commission and vice chairman of the China Energy Research Association, said that from a global perspective, the level of development in different regions is not the same, especially in some underdeveloped areas, such as Countries such as Africa and Southeast Asia do not have enough understanding of the changes in energy development methods. Therefore, the task of promoting and promoting the concept of global energy internet in our country is very arduous.
In recent years, although China's energy Internet-related technologies and equipment have achieved some essential breakthroughs, there are still many technologies that require continuous innovation in areas such as improvement of energy efficiency, improvement of intelligence, and improvement of the overall level of equipment manufacturing processes.
"The advancement of the global energy internet project is not only a technical and economic issue, but also a complex issue of international relations." Zhang Yibin believes that to run a large-scale global energy Internet system requires market transactions, mechanisms, and dispatch. Do a lot of breakthrough mechanism design work. The need for strong support from relevant government departments is not only the support of attitude but also the support of policies, laws, etc., and even some political cooperation.
According to Fei Zhirong, deputy secretary-general of the National Development and Reform Commission, China will steadily promote the construction of domestic energy Internet, optimize the layout of the power grid, and improve the ability to optimize the allocation of domestic energy resources. Accelerate the construction of energy Internet demonstration projects, actively research and propose supporting policies and measures, and reserve sufficient development space for new modes of energy internet and new business development.
In addition, China will focus on countries related to the “Belt and Road Initiative†to speed up the implementation of a number of projects with mature conditions and significant benefits for clean energy development and grid interconnection and interoperability projects, further improve and expand existing oil and gas strategic transportation corridors, and strengthen cooperation with Southeast Asia and other neighboring countries. Research on Network Planning of the State Grid.
