The concept of smart grid initiated by Western countries is quickly moving from theory to practice in China.
According to the latest data provided by the Ministry of Smart Grid of the State Grid Corporation of China: In the past four years, a total of 303 smart grid pilot projects have been arranged, 251 pilot projects have been completed and put into operation to cover various majors of the power grid, and the "Smart Grid Technology Standard System Plan" has been formulated and issued. Eight professional branches, 26 technical fields, and 92 standard series were systematically put forward, and 13 proposals for smart grid international standards were submitted.
In addition, China Southern Power Grid Corporation also organized and conducted strategic planning and research of smart grids, and conducted a large number of pilot projects including flexible HVDC transmission and intelligentization of substations.
From 2010 to 2012, "strengthening the construction of smart grids" was written three times in China's government work report and included in the national "Twelfth Five-Year Plan" outline. In the past four years, as a national strategy, the smart grid has been highly valued and rapidly promoted by the Chinese government and the electric power industry. The great achievements in this field can be defined as follows: China is increasingly becoming a leader and relevant standard of smart grid practice in the world. The leader of the formulation.
What kind of smart grid is clearly established in the development of the controversial disputes has once caused immense controversy in China.
As early as the concept of smart grid was introduced into China, all walks of life in China unanimously considered this to be the main direction for the future development of the power grid. There is a consensus on the necessity and importance of building a smart grid. However, opinions on how to develop it are different.
It is the choice of the smart grid development model that focuses on power distribution and electricity use in Europe and the United States, or the development of China's unique smart grid, which has become the focus of debate, based on China's energy structure and the rapid development of clean energy.
"The main reason is that the smart grid is a new thing. No one has ever seen it. There is no experience to learn from it. But then, we gradually realized that the development stage of each country is different, and the situation of each grid company is different. Therefore, there will certainly be differences in the understanding of the smart grid,†Shen Jiang, deputy director of the State Grid Corporation of China Smart Grid Department, told reporters.
In May 2009, at the UHV International Conference held in Beijing, the State Grid Corporation of China first proposed the strategic goal of building a strong smart grid, and further clarified that “Ultra high-voltage power grids are the backbone grids and coordinated development of all levels of grids is The concept and connotation of a strong smart grid characterized by information, automation, and interaction.
The industry believes that the concept of this development is fully taken into account that China's energy structure is dominated by coal, coal resources are mainly distributed in the north and west regions, and energy consumption is mainly concentrated in the more economically developed central and eastern regions, that is, energy must be realized The basic conditions of the scope optimization configuration.
“Smart grids have the same meaning in the world, but countries have different interpretations based on their own development needs. But the power grid must first be strong and strong is the basis for the development of smart grids. Without a strong grid, what about intelligent development?†Secretary-General of the Union Wang Zhixuan said in an interview with reporters.
Based on its own reality, China Southern Power Grid Corporation has researched and put forward the development orientation of “focusing on the core technologies of the South China Power Grid, using modern information technologies to accelerate the upgrading of traditional power grids, and building smart, efficient, and reliable power gridsâ€.
The development of the smart grid of two major power grid enterprises in China has been made clear.
In fact, in the two years after the development of the smart grid, disputes over its definition and direction have gradually disappeared. There is no way to perfect it, and it is constantly improving and improving in exploring the pilot.
“Now, the concept of smart grid development in the State Grid has become more and more the same with the world, that is, pay more attention to the new energy access and demand side of the intelligent, of course, also includes a wide range of energy resources allocation.†Shen Jiang Told reporters.
Pilot theory advanced quickly into practice December 25, 2011, Zhangbei County, Hebei Province.
The important pilot project of the smart grid, the National Wind Energy Storage and Demonstration Project, was officially completed and put into production. This is the first and the world’s largest new energy comprehensive utilization project integrating wind power generation, solar photovoltaic power generation, energy storage, and intelligent power transmission, and is expected to solve the problems faced by China’s large-scale development of new energy. Power generation internet problems.
“The wind turbines generate more electricity at night and the solar panels generate more electricity during the day. Through this demonstration project, the wind and solar power are complemented. In addition, the adjustment of energy storage batteries and the coordination of the smart grid can solve the problem of the randomness and volatility of new energy generation. The conventional coal-fired power generation is stable and controllable,†said Zhao Yuzhu, deputy general manager of the North China Power Grid Corporation, on the day of production.
The Zhangbei Scenic Spot Storage and Demonstration Project is just a circle on the entire Chinese smart grid pilot site.
From theory to practice, it is a difficult and challenging starting point for smart grids without precedents. As a result, China's two major power grid companies have chosen the pilot development path first.
During the three years from 2009 to 2011, the State Grid Corporation of China carried out more than 300 pilot projects of the smart grid around the power industry's "power generation, transmission, power transformation, dispatch, distribution, and power supply."
Regarding the progress of the pilot project, Shen Jiang said, “Generally speaking, our pilot projects can be summarized with a wide range of coverage, large-scale construction, rapid advancement, and good application effects. Up to now, intelligence has been quantitative and professional. The main tasks of the pilot phase of the power grid were basically completed, including the two smart grid integrated demonstration projects of the Shanghai World Expo Park and the Tianjin Zhongxin Eco-city. Among these, eight projects have achieved good progress.†The eight types of projects include renewable energy generation and grid connection, smart substations, electric vehicle replacement and charging service networks, smart grid dispatching technical support systems, power transmission and transformation equipment condition monitoring systems, electricity consumption information collection systems, and distribution automation. Smart electricity service platform.
In the south of China, the exploration and practice around the smart grid are also progressing in an orderly manner.
It is reported that China Southern Power Grid Company has implemented flexible HVDC transmission, intelligentized substations, all-round management of power transmission and transformation equipment, research on microgrid planning technology, and comprehensively carried out power distribution network resources in improving user energy efficiency and quality service management level. Control, multi-dimensional network work and energy management, interactive power grid construction, charging and replacement of power station for the construction and operation of smart grid pilot projects.
“China's smart grid construction is exciting, and we are gradually advancing the transmission grid from the ground up. The pace of construction is rapid. I am very optimistic about the prospects of China's smart grid.†The chairman of the IEEE Standards Association’s Power Systems Network Security Working Group commented on the current Chinese smart grid Construction process.
Fully break through China's practice to lead the world and make it advanced.
China's progress in the construction of smart grids has already taken precedence over the world. This has become the consensus of all countries in the international conferences on smart grids in recent years.
This lead is comprehensive.
Such a set of data from the national grid can reflect the tremendous achievements of smart grid construction: the establishment of 65 intelligent substations of 110 kV to 750 kV; and the construction and commissioning of 243 standardized charging and switching stations and 13 283 substations covering 26 provinces and cities. Charging piles; put into operation 11 sets of smart grid dispatching technical support systems; completed the deployment of the main station of transmission equipment condition monitoring system in 15 provinces; 90.69 million users have realized the automatic collection of power consumption information; built intelligence in the core areas of 23 cities; Distribution network; 28 smart electricity communities have been built, and the service platform has covered 35,000 users. ... In Wang Zhixuan's view, China is currently at the forefront of the world in most fields of smart grid construction, especially in applications. "In addition, China's smart grid standards and proposals are increasingly accepted and accepted by the International Organization for Standardization." Wang Zhixuan told this reporter.
Shen Jiang summarized the achievements of the four-year smart grid construction as “the formation of a smart grid concept for the system, the promotion of comprehensive pilot project construction, the establishment of a sound technical standard system, the rapid improvement of the level of research and development of smart devices, and comprehensive test testing. "The ability to have" overall progress.
Among these, the establishment of a technical standard system and the improvement of the level of equipment research and development have made China Grid people the most proud.
It is reported that in the past four years, the State Grid has formulated and issued the "Smart Grid Technology Standard System Plan", systematically proposed eight professional branches, 26 technical fields and 92 standard series, and recommended 22 core standards. A total of 285 smart grid technology standards (including national standards and benchmarks) have been compiled or adopted, and 137 smart grid enterprise standards have been issued. The smart grid technology standards system has been improved, effectively guaranteeing the construction of pilot projects.
“At the same time, we actively participated in the formulation of industry standards, national standards, and international standards. We submitted 13 proposals for smart grid international standards. As the main drafting unit, we also participated in the compilation of 4 national and 22 industry standards. There was a profound effect outside," Shen Jiang said.
As a new power grid development field, seizing this opportunity for development will enable China's electric power equipment R&D technology to pass through corners in Europe and the United States.
In fact, such goals have been initially achieved.
Up to now, the State Grid Corporation of China has taken the lead in formulating and publishing the “Smart Grid Key Equipment (System) Development Plan†including 7 technical fields, 28 technical topics, and 137 key equipment (systems) in the world, becoming a key smart grid device. Development guidelines. The plan effectively guides the power equipment manufacturers to enhance their R&D and innovation capabilities and promote their transformation and upgrading. "Sixty key equipments have been successfully developed and successfully applied in pilot projects," Shen Jiang told reporters.
This consensus has been formed: China is and has become an important driving force for the development of the world's smart grid.
China's smart grid has been piloted into a comprehensive construction phase. Based on a solid foundation that has been laid, China's power grid will enter an era of intelligence.
