China has many advantages in developing smart grid

China has many advantages in developing smart electricity. Smart electricity is the national policy of the United States, the European Union and other developed countries. The global financial crisis gave birth to "smart electricity". In the absence of a financial crisis, the "prosperity" of the virtual economy blurred a series of sharp contradictions between the real economy and energy resources and the ecological environment. The reform of electricity is neither important nor urgent nor possible. "Smart electricity" will play an important role in the economic recovery and reshaping competitiveness of developed countries, but its significance is not just an expedient measure to deal with the current global financial crisis

international smart electricity background

in the context of the world's "green industry revolution", over the past 20 years, the world's developed countries, led by the government, have put forward a series of strategic plans for power development. In the early stage, it focused on power generation and achieved many positive results. For example, the United States has successively put forward CCT clean coal development plan, CCPI clean coal innovation and development plan, future Gen major demonstration project plan, etc. In 2003, the U.S. government first put forward a relatively complete strategic concept of smart electricity in the "electricity 2030" plan. "Smart" is a means to serve the purpose and purpose of its strategic concept. After that, it has carried out a large number of technical research, industrial demonstration, social pilot and local commercial operation. Now it has become an important national policy of the U.S. government. In 2005, the EU raised smart electricity to a national strategic position for research. The definition of smart electricity by the U.S. Department of energy is: smart electricity is a modern electricity that uses advanced sensing technology, communication technology and control technology to ensure more efficient, economic and safe power generation, transmission and power supply. It integrates a large number of innovative technologies and means beneficial to the society in the fields of power generation, transmission and distribution and electrical equipment to meet the changing future social needs

the proposal and implementation of the strategic purpose, core and technical management measures of smart electricity marks that the world's power development has entered a new historical stage. The "unified smart electricity" of the United States and the "super smart electricity" of the European Union are both figurative names. The reason why they are recognized by the world is not because of their names, but because their strategic ideas are in line with the purpose and purpose of today's energy reform and have been partially proved to be effective

due to different national conditions and power development stages, the definition, content and focus of smart electricity in different countries will be different. However, the transformation purpose and core of "safe, economic, efficient, clean and low-carbon" should be the same. The characteristics of advanced sensing, communication and control technologies, digital management, intelligent decision-making, interactive trading and other technical management measures are the same. It can be considered that the purpose, core The proposal and implementation of technical management measures marks that the world power development has entered a new historical stage. Both "smart electricity" and traditional electricity must follow the basic laws of electricity, and both contain the same basic concepts that are not limited by time. Their core, basic forms and key technologies are the same and different

the smart power strategy proposed by European and American developed countries focuses on the power supply side, including the acceptance of renewable energy, intelligent management on the demand side, two-way interaction, and a wider range of high-voltage connection. It conforms to the actual national conditions, power development stage and basic status quo of European and American developed countries

from the perspective of China's specific national conditions, the strategy known as "intelligent power system" in China is more accurate. Only the comprehensive reform, innovation and development of power generation, transmission, supply and utilization can truly achieve the purpose and purpose of power reform. These four aspects of reform, innovation and development are interrelated and promote each other, and need to be promoted in a coordinated and orderly manner. Excessive advance or lag in any aspect will seriously affect the process of China's power development. From the perspective of the broad concept of electricity, power reform and innovation with high efficiency and low carbon as the core, and international easy cognition, it can be called smart power strategy, which also has more characteristics of the times than previously called power development planning

China's smart power strategy research should include transformation, innovation and development in four aspects: generation, transmission, supply and utilization. The national conditions and power development stages different from those of developed countries should be taken into account. For example, China will continue to meet the demand growth with rapid power development in the next 20 to 30 years, the regional distribution of energy resources including renewable energy and demand is uneven, and the power structure dominated by coal power will exist for a long time. The basic status quo different from that of developed countries must also be taken into account, such as the optimization and adjustment of China's primary energy consumption structure, the optimization and adjustment of power supply structure, the distributed energy system, the research on the sustainable development of traditional energy, and the basic research on the application of renewable energy

China's smart electricity strategy, cognitive level and scientific attitude. The correct formulation of China's smart power strategy today and its successful implementation in the future mainly depend on our cognitive level and the scientific attitude of seeking truth from facts. Without a deep understanding, it is impossible to turn the severe challenges endangering our sustainable development into our development opportunities. Without a scientific attitude of seeking truth from facts, we cannot have a correct response strategy

inevitability of world energy and power reform

deep level reform of world energy. Energy has always influenced and changed the destiny of mankind and the world in the past, present and future. Due to the dependence of economic and social development of all countries in the world on energy, the uneven economic development and regional distribution of energy in all countries in the world, the limitation of global fossil energy resources, the restriction of the earth's climate change on the utilization of fossil energy, as well as the political and economic factors related to global economic integration, geopolitical conditions, energy strategic security and competitive situation of all countries, It has formed a variety of complex contradictions around energy in the world today, which have become increasingly acute over time, posing a serious challenge to the sustainability of human social development, thus brewing and actually launching the world "green industry revolution", the core of which is the low-carbon economy. The essence of low-carbon economy is high energy efficiency and clean low-carbon energy structure, including the transformation of economic development mode, energy science and technology innovation, system innovation, the transformation of people's lifestyle and the fundamental transformation of human survival and development concept. This is the necessity of human historical development, and low-carbon economy has also been included in the core of China's development plan. Since last autumn, the global financial crisis has more intensively triggered a profound change in the world's energy

global fossil energy resources are limited. According to the world energy statistics of bp2008, 133 years of coal, 41 years of oil and 60 years of natural gas can be exploited for fossil fuels in the world, and 82 years of natural uranium can be supplied at the current consumption level; China can mine coal for 45 years, oil for 11.3 years, natural gas for 27.2 years, and natural uranium resources for 40million kW nuclear power years. According to the 2009 China energy blue book, according to the current energy demand level, the assurance degree of China's remaining coal reserves is less than 100 years, oil is less than 15 years, and natural gas is less than 30 years. If the energy demand in 2020 is estimated, coal, oil, and natural gas will be reduced to 30, 5, and 10 years respectively. Although the above years will change with the increase of proved rate and the change of consumption level, the limitation of global fossil energy resources is obvious. However, renewable energy resources are large and inexhaustible. Only China's land and offshore wind energy technology can develop more than 500million kilowatts, China's rooftop solar energy utilization can reach billion kilowatts by 50%, and China's 5% shammu solar energy development can exceed 3billion kilowatts. However, due to various technical and economic reasons, it is difficult to achieve large-scale application in a short time. By the middle of this century, it is estimated that the global renewable energy utilization can only reach 30%-50% of the world's primary energy consumption. In short, the limitation of global fossil energy resources determines the inevitability and urgency of world energy reform

the severity of global warming. People have realized that the earth's climate warming poses a serious threat to human survival. Scientists believe that when the atmospheric carbon dioxide content reaches ppm, it is optimistically estimated that 550ppm, that is, if the global average temperature rises by 0.6 degrees Celsius or 1.6 degrees Celsius, the earth will have irreversible catastrophic consequences. In 2008, the content of carbon dioxide in the earth's atmosphere reached 386ppm, while it was only 280ppm before the world industrial revolution. The global average temperature has risen by 0.74 ° C in the past 100 years. In particular, the global temperature has risen rapidly in the past 30 years. The average temperature in the northern hemisphere in the last 50 years of the 20th century is the highest in the past 1300 years. The average temperature rise in China in the past 50 years has reached 1.1 ° C. the world has been the hottest decade since its records Ear width --- the width of the reed in the ear. The earth is on the edge of devastating climate chaos. In 2007, the global carbon dioxide emissions reached 27.6 billion tons, 90% of which came from energy production and consumption. It is expected that the annual average growth will be about 2% by 2020, and zero growth will be expected by 2030. The global climate change response has become a national strategic issue of all countries in the world. Some countries have proposed that the global ecological warning line is that the global average temperature rise can no longer exceed 2 degrees Celsius. This issue has also become the primary task of the United Nations. The United Nations believes that the international community has not had much time to waste on the issue of climate change, and the temperature rise is much faster than expected. The severity of global warming points out the inevitability and urgency of energy reform

the earth can only carry China with a correct energy strategy. China has now become the world's largest energy producer. In 2020, China's per capita GDP is expected to reach US $5000. The primary energy demand is 4.5 billion tons of standard coal. The pattern that coal can be basically self-sufficient accounting for about 60% of the total energy demand cannot be changed. China's dependence on foreign oil may exceed 60%. Although the carbon dioxide emissions per unit of GDP may be reduced by 50% compared with 2005, the total emissions will increase by about 60%. At present, the United States' dependence on foreign oil is less than 30%, and its total imported energy is at the level of 35%. In addition to the economic consumption of US $1trillion, it has brought many problems, including national security. China should take warning. Therefore, China's future economic aggregate, primary energy demand and greenhouse gas emissions determine that the earth can only carry China with a correct energy strategy

among the world's energy reforms, power is the most important and potential. The ultimate goal of world energy reform is carbon-free and low-carbon energy. Without carbon-free and low-carbon energy, there will be no low-carbon economy. Energy science and technology innovation is the core of realizing low-carbon economy. Energy reform involves many aspects, mainly focusing on the conservation of fossil energy and the use of renewable energy, involving three major fields: industry, construction and transportation. The primary energy consumed by the world's electricity accounts for more than 40% of the world's total consumption, of which fossil energy accounts for nearly 90%. However, the terminal efficiency of the conversion of fossil primary energy from electricity is only 30%, and the greenhouse gas emitted by electricity accounts for more than 40% of the world's total emissions. It can be seen that electricity is the most important and potential energy change in the world. In 2008, China accounted for 6% of the world's GDP, 18% of the world's primary energy consumption, 20% of the world's carbon dioxide emissions, and 40% of the country's total carbon dioxide emissions from electric power. China cannot stay out of the world's energy and power reform
