Smart grid is an important component of national energy development strategy

The 398th Xiangshan Science Conference with the theme of “China's smart grid key technical issues and development strategy” was held in Beijing recently. The experts at the conference focused on the connotation, development strategy, key development directions, and key technical fields of China’s smart grid. Breakthroughs and other issues, and made recommendations for China's smart grid overall development strategy and national policies.

The hot issues that all parties pay close attention to are smart grids, which are based on the physical network of power systems, and use advanced sensing, communications, information, control, and energy storage technologies to form an advanced power network. The goal is to achieve a safe and efficient power system. , flexible and economical operation. The smart grid is characterized by deep information, comprehensive interaction, clean energy, high efficiency of assets, marketization of the system, security of the power grid, high degree of automation, and wide distribution. It is equipped with intelligent monitoring and diagnosis of all aspects, all processes, and all factors. The communication, control, and decision-making capabilities are the comprehensive transmission platforms for electricity and information. The intelligentization of the power grid is a long-term and continuous process. The smart grid technology will continue to innovate with the development of the power grid and technological advancement.

In order to meet the requirements of economic and social development and respond to global climate change and energy crisis and the major challenges facing the power grid, the United States, Europe and other countries have taken smart grid construction as an important guarantee for the development of new energy generation, Australia, Japan and South Korea. Other countries and regions have proposed their own smart grid development programs. ****** On June 7, 2010, he spoke at the conference of the academicians of the two academies and proposed to “build a smart, efficient, and reliable power grid system covering urban and rural areas.” The smart grid has become a hot issue of concern to all parties in the society, and will have a major impact on the future power industry, energy sector and even information, communications, home appliances, automobiles, construction and other industries.

The conference executive ** and Professor Yong Yong of Tsinghua University pointed out in the theme review report titled “Technology Drivers and Development Strategies for China’s Smart Grid Development” that the significance of China’s development of the smart grid lies in the implementation of “China’s response to climate change The strategic measures of the Plan are important support for further promoting the sustained and rapid development of the economy and society; the only way for the optimization and efficient use of energy structure; the strategic safeguard measures for China's electricity supply security; and the importance of gestation and formation of strategic high-tech industries. engine.

The conference executive **, Academician Yu Jixin of Tianjin University believes that the smart grid can realize the safe and stable operation of large systems, reduce the risk of large-scale power outages, and maximize the utilization rate of the equipment; the overall idea of ​​the smart grid is intelligent, efficient, inclusive and motivated. Etc.; smart grid technologies should include smart grid technologies, smart grid-enabled technologies, and technologies for creating platforms for smart grids.

Experts with smart grids with Chinese characteristics believe that the development strategy of the smart grid industry is an important part of the national energy development strategy. Building a smart grid will help adapt to the rapid economic and social development in China, respond to the environment and climate change, and break through the grim situation in China. The supply of energy resources is bottlenecked, energy structures are optimized, safe, efficient and clean power production, transmission and use are achieved, and the sustainable economic and social development of our country is promoted.

The experts stressed that we should pay attention to the differences between China's power grid and European and American power grids in terms of equipment and equipment, power consumption structure, management model, and overall conditions for social and economic development. We should also pay attention to the new trends and new demands for electricity in China and effectively put forward a smart grid in China. development strategy. The development of smart grids in China should be based on China's basic national conditions, and in-depth analysis of China's economic society, energy supply and sustainable development of the power industry is facing major needs and key issues, "to me as the main, seek truth from facts," build with Chinese characteristics Smart grid to promote sustained and rapid economic and social development, adapt to the multiple constraints of energy, resources, and the environment, realize efficient use of electricity as the center of energy cascades, meet the diversified power needs of customers, and achieve efficient and optimized energy resources. Configuration.

Experts suggest that we should develop the top-level design of the smart grid from the macro level, clarify the core requirements and fundamental goals for building a smart grid in China, form a phased development goal and roadmap for building a smart grid in China, and introduce laws and regulations that are compatible with the development of smart grids. Strengthen macro-management and system construction, and promote the comprehensive, healthy and orderly development of China's smart grid. At the same time, comprehensive basic research should be carried out as soon as possible to analyze the major needs of China's future energy and power fields, clarify major scientific issues in the field of smart grids, and support the research, development, and innovation of smart grid key technologies.
