China becomes the biggest country for attracting smart grid technology

Since the beginning of the 21st century, issues such as energy shortages, resource constraints, and climate change have become increasingly prominent. In the past decade, the world’s energy consumption has grown by a cumulative 28%, nearly 1 times higher than the consumption growth rate in the last decade of the last century. Global energy security and energy There are major challenges in terms of efficiency, energy and environment. Building a modern power grid that meets the needs of economic and social development in the 21st century and responding to the new challenges of global energy development has become a universal consensus and strategic choice for all countries in the world.

global cooperation

The article “Smart Grid: From Innovation to Development” recently published in the “European Newsletter” pointed out that the development of smart grids is dedicated to involving both the energy industry and the general public in this discussion, and the strategic goals of smart grid construction are very clear. The political signal gave European participants an expectation, which created a very beneficial environment for long-term R&D and investment. What kind of enlightenment does this have for China?

At the International Symposium on Smart Grids 2011, the European Union ambassador to China, Ed, said that for China, the smart grid will become a backbone network for future sustainable cities. "The speed and scale of China's urbanization process has brought many challenges. The smart eco-city supported by the smart grid will become the meeting point for China-EU interests. China and the European Union will have the opportunity to work together to shift the focus to the smart grid in cities. Actual application, and work together in this area."

Aide revealed that the future China-EU sustainable urbanization partnership will become one of the highlights of the China-EU Summit. “We will sign a memorandum together to enable us to jointly formulate a more unified policy at the regulatory level, and our government also has the responsibility to ensure a huge market for smart grid-related equipment and provide a globally open competitive platform. ”

In addition to broad market prospects, cooperation in the standardization field is also becoming an important area for future international cooperation in smart grids. US Ambassador to China Gary Locke pointed out that at present the U.S. Department of Commerce’s National Standards Technical Association is working hard to develop some open standards for creating smart grid markets around the world. He reminded that the key point in the process of smart grid construction is international cooperation. All countries must have common goals. If the smart grid is fragmented and fragmented, it will lose economies of scale, causing some key product markets to become smaller and the cost to become higher. And when the market is divided, countries will suffer non-tariff trade barriers. The risk will also increase.

"Not just interoperability. If a device is made in China, then it is very important that they can find in the European or American market that their equipment is also in line with local standards and that they can successfully enter the local market. I think This kind of mutual exchange is very urgent. The first smart grid standard in the European Union will be introduced at the end of 2012. The newly established international smart grid initiative will also help the development of this area, said Ed.

The largest market to absorb

At present, the development of smart grids brings unprecedented construction of telecommunication fields and information systems, which greatly promotes the investment in smart grids worldwide. The research findings of the headquarters of the British intelligent innovation observation company show that in 2030, the US investment in smart grid smart infrastructure construction is expected to reach 60 billion US dollars, "can be seen from a report from Parker Research Corporation, as of 2017 Investment in the Asia-Pacific region will reach 171.3 billion U.S. dollars. By 2020, European investment in smart grid technology is expected to reach 80.3 billion U.S. dollars, and China will become the largest consumer market."

Prior to this, China's first smart grid integrated demonstration project was successfully put into operation in the Sino-Singapore Tianjin Eco-City. It is understood that this demonstration project covering 31 square kilometers and covering 12 sub-projects in 6 major areas is currently the world's most comprehensive and most complete smart grid system.

Although China's smart grid is still in its infancy, the powerful information collection and processing system it needs will take a long time to complete. However, China's smart grid construction and investment are also much faster than other countries.

At the above-mentioned forum, Liu Zhenya, general manager of the State Grid Corporation of China, stated that smart grid construction has been included in China's "Twelfth Five-Year Plan". The State Grid plans to invest 1.6 trillion yuan in the next five years to build a smart grid; plans for 2020 The formation of "five vertical and six horizontal" ultra-high voltage transmission backbone grid, in China basically achieve strong smart grid and UHV line system coverage. In recent years, China's power grid's experimental research capabilities have been fully enhanced. UHV AC, DC, high altitude, and engineering mechanics test bases have been established, and national R&D (testing) centers for large-scale wind power grid integration, solar power generation, and smart electricity use technologies have been established, forming a test and research system with internationally advanced standards. A large number of achievements have been made in the research and development of large-capacity power transmission equipment, energy storage batteries and other technologies, and 1,529 patents have been obtained, and the power grid technology standards system has been continuously improved. Established a systematic UHV and smart grid technology standard system, issued 267 enterprise-level standards, 39 industry standards, and 20 national standards, and prepared 7 international standards.

According to briefings, China has carried out early explorations of the development of smart grids. At present, the power grid optical fiber communication network and management information system have been fully completed, and a large number of achievements have been achieved in scheduling automation, real-time dynamic monitoring of power grids, flexible AC power transmission, intelligent substations, and distribution network automation, etc., in order to promote the development and utilization of clean energy in China. It has laid a solid foundation for improving the efficiency of energy use and realizing mutual interaction between the power grid and users.

Liu Zhenya said: “In 2015, the State Grid will cover 88% of China’s land area and support 90 million kilowatts of wind power and 8 million kilowatts of solar power generation. By 2020, the national grid will form “five vertical and six horizontal”. UHV backbone grid, real-time monitoring of power grids and intelligent dispatch control of eastern and western energy sources."

Since the concept of "strong smart grid" was proposed for two years, the promotion and popularization of smart grid in China has been proceeding in a pilot manner. At present, China has built 6 smart electricity pilot communities, 22 smart electricity communities are under construction, and the service platform covers 35,000 customers. At the same time, two large-scale pilot areas for the Shanghai World Expo Park and the Tianjin-Binhai New District's Sino-Singapore Eco-city have also been established. The completion of the smart grid will provide strong support for China's large-scale energy management.
