In advancing the construction of smart grids, standard setting is of utmost importance. The significance of the standards first for building a smart grid is self-evident. State Grid Corporation of China attaches great importance to the standardization of smart grid development and application of the work, the company set the power of the entire group, comprehensively combing smart grid related standards at home and abroad, speed up the research and establish to cover generation, transmission, transformation, distribution, electricity, scheduling The standard system of the links and communication information platform is to solidify the foundation for the development of a strong smart grid, and actively participate in the development of relevant international standards and norms for smart grids, so as to increase China's strength in participating in the international competition in the smart grid field.
June 29, 2010, the State Grid Corporation officially released the "smart grid technology standard system planning." Once the plan was announced, it received widespread attention from the industry, especially in the field of equipment manufacturing.
To enable readers to further understand the construction of China's smart grid standards, the deputy chief engineer of China National Electric Power Research Institute, Bai Xiaomin, one of the principals of the research on the smart grid technical standard system of the State Grid Corporation of China, made a Characteristics and the impact on the equipment manufacturing industry and other aspects of the magazine introduced the relevant circumstances.
Standard setting should be based on practice
"The establishment of the national grid company's smart grid standard system is mainly based on three important considerations." Bai Xiaomin said.
First of all, the establishment of a standard system must meet the needs of comprehensively promoting the construction of smart grids, and should not be biased in a particular area of ​​expertise, such as simply considering electricity or isolated automation.
Second, the establishment of a standard system must be closely integrated with the process of smart grid construction and must be combined with smart grid practices. The State Grid Corporation of China has carried out 21 types of 228 smart grid pilot projects in 26 provinces and cities. The practice of these projects requires the guidance of the standard system. The study of the standard system must also fully integrate and consider these pilot project needs. “Now, the State Grid Corporation of China is fully advancing the construction of smart grids. Various pilot projects are being constructed in different regions and systems across the country. These projects will lay a solid foundation for the development of our smart grid standards, and we will develop various specialties for the domestic and foreign power industry. The standards in the field provide systematic experience."
Third, the standard system must be operational. “The standard development plan we propose should integrate the development plans and recent work plans of each professional management department and professional field of the power grid company, and lay the foundation for the formulation of specific standards.â€
In April 2010, the State Grid Corporation of China completed the “Study and Formulation Plan for the Smart Grid Technical Standard System of the State Grid Corporation of China,†and researched and proposed the concept model of the Smart Grid Technology Standard System of the State Grid Corporation of China, which established “1 system and 8 professional branches. , 26 technical fields, 92 standard/series standards and several specific technical standards†standard system hierarchy.
Bai Xiaomin pointed out that this system is based on the needs of building a strong smart grid in China, combining the latest developments in the international smart grid standards and formulation work, and compiling the 779 international standards and 772 Chinese standards. “This has an important guiding role in the development of key equipment for smart grids in China and the formulation of relevant industry standards, national standards, and even international standards, and it is conducive to promoting and stimulating the orderly development of smart grids and related fields and industries.â€
According to the "Smart Grid Technology Standard System Planning," the State Grid Corporation of China will formulate smart grid technical standards in three phases. Bai Xiaomin stated that "the standards covered in the research project of the smart grid technology standards system do not include specific technical standards, but mainly set up a standard structural system to provide guidance for the follow-up of smart grid standards."
The formulation of standards requires a long-term process. According to Bai Xiaomin, “The most closely-related, most mature, most widely involved, and benchmarking standards for smart grids will be first introduced to guide the construction of smart grids.â€
A distinctive smart grid standard system
In recent years, the international standards system has been given a high degree of attention. Both IEC SG3 (Smart Grid Standards Strategy Working Group) and NIST in the United States have proposed the roadmap of smart grid standards, and proposed the conceptual model, core standards, and work recommendations for the standard system of the smart grid. IEC SG3 proposed 11 recommendations for advancing smart grid standards, and NIST put forward the first batch of 14 standards to be formulated first.
State Grid Corporation actively promotes cooperation and exchanges with international organizations such as IEC, IEEE and Europe, and other national standards organizations, and participates in international standardization work. In the standard system research process, not only the need for domestic smart grid construction has been fully considered, but also the need to promote the internationalization of standards.
“In terms of the internationalization of standards, we started from the key areas of the smart grid, selected our professional direction with strong research foundations and practical experience, and proposed standards for internationalization in response to standards that are focused and urgently needed at home and abroad. Work plan.†Bai Xiaomin said, “In the process of actively participating in the international standard strategy study, China Electric Power Research Institute proposed eight important recommendations for the smart grid technology standard system to the SG3 and was adopted by the SG3.â€
Compared with the international standard system research, the national grid company's proposed smart grid standard system has different characteristics in terms of systematization, conceptual model and professional field division, professional technical direction considerations, and standard planning. Bai Xiaomin attributes this to the following four aspects:
(1) Systematic. In close connection with the deployment of the national grid to build a smart grid, the proposed standard system covers all areas of the smart grid from power generation to electricity use. On the basis of systematic analysis of international and domestic standards, the new standard system includes the corporate standards of the State Grid for many years and the standards that have been combined with the requirements of smart grids in recent years, including the UHV standards. The built standard system is a system smart grid standard system.
(2) Comprehensiveness. The standard system takes into account the development needs of various professional fields. Divided into 8 professional fields, a comprehensive analysis of the construction of all aspects. The integrated and planning area has a special concern because it concerns the construction and design principles of the power grid, and it is a major issue in the construction of the national power grid. It is the basis for the safe and reliable operation of the power grid.
(3) Highlighted. The standard system divides 26 professional technical directions, including the main development directions of the smart grid and the focus of smart grid research and construction work. The proposed professional technology direction includes both large-scale renewable energy access in the field of power generation and hot issues such as access to electric vehicles and distributed energy.
(4) Integrity and openness. The standard system proposes 92 standard series. The internal logical relationships can be divided into "basic and comprehensive", "engineering" (including design, renovation, acceptance, testing), "operation and maintenance", "equipment and material", etc. Makes the follow-up of specific standards to establish and supplement the perfect context.
The smart grid standard system issued by the State Grid Corporation of China has established a good working foundation for the formulation and standardization of domestic standards. Recently, IEC SG3 is considering the system analysis of use cases based on the smart grid standard roadmap to establish the hierarchical relationship between standard system hierarchy and standard mapping relationships. As there are a large number of different types of pilot projects in the country, our smart grid construction is more systematic and broader than the foreign professional coverage. If we can combine the needs of pilot projects and the experience gained in the smart grid construction process, we will implement a standard system. The deepening research will play an important role in promoting the standardization of technologies in various professional fields. At present, we are actively participating in the deepening research of the standard system and the exchange and research work of international standards, further promoting domestic successful experience and products to adapt to international standards and requirements, and promoting the internationalization of smart grid standards.
How do companies choose
Smart grid is a brand-new system engineering, involving many disciplines and professional fields, connecting many economic and industrial issues in it. The industry has reached a consensus on the strategic significance and implementation of the smart grid, and the smart grid has an important role in promoting the optimization and upgrading of the energy industry, the development of new energy industries and basic industries, innovation in equipment manufacturing, and energy conservation and environmental protection. The national energy strategy and the transformation of the economic development mode are of great significance. Bai Xiaomin believes that under this background, many power transmission and transformation equipment companies that have experienced decades of maturity will face the problem of how to adapt to the needs of the smart grid.
Smart grid, standards first. This is the most obvious highlight of China's smart grid construction, and it also shows that our country has placed unprecedented emphasis on and attention to the smart grid. In the past, technical standards were often introduced after the product had been developed and operated, lagging behind the development of the industry. The pre-announcement of the smart grid standard system avoids resource waste and duplicate investment, regulates the industry's orderly competition, and guides enterprises to develop applicable products and systems.
Bai Xiaomin pointed out that the introduction of smart grid technology standards system has made equipment manufacturing companies face more severe technical challenges, but it also ushered in new opportunities for development. This will break the original market structure of the equipment manufacturing industry, trigger a new round of competition in the manufacturing industry, and lead to profound changes in the equipment industry. In this far-reaching industrial change, where should companies go? Bai Xiaomin believes that enterprises should pay special attention to the progress of international and domestic technical standards systems and actively participate in the formulation of standards.
Bai Xiaomin emphasized that as an important guiding and guiding document for guiding the development of technology, enterprises can understand the overall picture of the system, related priorities, and the relevance of each other through the standard system, so as to grasp the initiative of product development. If companies can participate in or lead the formulation of standards, they will help the company's market competitiveness. Products that do not meet market needs and standards will lose business opportunities, and will also affect the survival and sustainable development of the company.
From the perspective of new product development, Bai Xiaomin made some suggestions for equipment manufacturers.
First of all, in the initial stage of the project, we must pay attention to whether various programs can effectively solve the demand problem. The standard will emphasize the needs of users at this stage. It requires companies to select products that have market prospects in light of grid and user needs, and must use standards that meet user requirements. At the end of the project, appropriate standards should be used to guide technical design and specifications. System designers and integrators can interact with each other and even use interchangeable devices.
In addition, new product development must also consider the following issues: to be compatible with, integrate with and use existing mature power systems; systematic and comprehensive project projects must consider multiple interests and meet the requirements of users, equipment manufacturers, power companies, and regulatory agencies. Adhere to the principle of standardization, while focusing on the constraints of standards, encourage innovation, develop distinctive and competitive products; standardize necessary interfaces and products, avoid standardization of specific applications and business cases, and focus on descriptions. General requirements, avoiding standardization of details; avoiding standardization of solutions or applications themselves, otherwise it will seriously hinder the innovation and development of smart grids.
Finally, Bai Xiaomin stated that at present, many smart grid standards are still in the development stage, and many technical equipment are still immature. With the full development of smart grid construction, standards systems and standards must be supplemented and improved as needed. "In this process, companies will face many opportunities and opportunities for innovation. We also urgently need the close cooperation between electric power companies, equipment manufacturing companies and related organizations to jointly improve and promote standards development so that standards can be implemented in smart grids. The construction will play an important guiding role.â€
