    ¡°Secondly, I believe that the development of smart grids is also an inevitable choice for social and economic development. First, in order to realize the development, transmission and consumption of clean energy, the power grid must improve its flexibility and compatibility. Second, in order to withstand increasingly frequent natural disasters and In the face of external interference, the power grid must rely on intelligent means to continuously improve its security defense capabilities and self-healing capabilities. 3. In order to reduce operating costs and promote energy conservation and emission reduction, the power grid operation must be more economical and efficient, and at the same time, electrical equipment must be intelligently controlled. Reduce electricity consumption as much as possible. The rapid development of distributed power generation, energy storage technology and electric vehicles has changed the traditional power supply and consumption model, prompting the continuous integration of power flow, information flow and business flow to meet increasingly diverse user needs. Finally, I believe that in the future, green energy-saving awareness will become the mainstream of the world. After all, the earth¡¯s resources are limited. That is, driven by green energy-saving awareness, smart grid will inevitably become a key area of ??development for countries around the world. . A smart grid is an electricity network that is self-healing, allows consumers to actively participate, can recover from attacks and natural disasters in a timely manner, accommodates all generation and energy storage, can accommodate new products, services and markets, optimizes asset utilization and operating efficiency, Providing power quality for the digital economy. The smart grid is built on an integrated, high-speed two-way communication network and aims to utilize advanced sensing and measurement technology, advanced equipment technology, advanced control methods, and advanced decision support system technology to achieve grid reliability. , safe, economical, efficient, environmentally friendly and safe to use, its development is a gradual and step-by-step evolution, a complete change, and the product of the coordinated development of existing technologies and new technologies, in addition to networks and smart meters. In addition, it also covers a wider scope. The construction of a strong smart grid with UHV power grid as the backbone grid, coordinated development of power grids at all levels, and characterized by informatization, automation, and interaction, comprehensively improves the security, economy, and efficiency of the power grid. Adaptability and interactivity, strength is the foundation, and intelligence is the key. I believe that the importance of building a smart grid to our country is mainly reflected in the following aspects: First, my country¡¯s smart grid has strong resource optimization and allocation capabilities. After completion, it will realize cross-regional, long-distance, large-capacity, low-loss, and high-efficiency transmission of large-scale hydropower, large-scale coal power, large-scale nuclear power, and large-scale renewable energy, and the inter-regional power exchange capacity will be significantly improved. A high level of safe and stable operation. The security, stability and power supply reliability of the power grid will be greatly improved. The defense lines at all levels of the power grid will be closely coordinated to withstand emergencies and serious faults, and can effectively avoid large-scale cascading failures. occurrence, significantly improve power supply reliability and reduce power outage losses. Third, adapt to and promote the development of clean energy. The power grid will have control mechanisms such as wind turbine power prediction and dynamic modeling, low voltage ride-through and active and reactive power control, and rapid adjustment of conventional units. , combined with the promotion and application of large-capacity energy storage technology, the operational control capabilities of clean energy grid connection will be significantly improved, making clean energy a more economical, efficient and reliable energy supply method.  Fourth, realize highly intelligent power grid dispatching.  Comprehensively build a horizontally integrated and vertically connected smart grid dispatching technology support system to realize online intelligent analysis, early warning and decision-making of the power grid, as well as efficient regulation of various new power generation and transmission technology equipment and lean control of AC and DC hybrid power grids.  Fifth, realize efficient utilization of power grid assets and full life cycle management.  It can achieve overall management throughout the life cycle of power grid facilities.  Through smart grid dispatch and demand-side management, the number of hours of grid asset utilization has been significantly increased, and the utilization efficiency of grid assets has been significantly improved.  Sixth, realize convenient interaction between power users and the power grid.  An intelligent power interactive platform will be formed to improve demand-side management and provide users with high-quality power services.  At the same time, the power grid can comprehensively utilize distributed power sources, smart energy meters, and time-of-use electricity price policies to effectively balance the grid load, reduce load peak and valley differences, and reduce grid and power supply construction costs.  Seventh, realize informatization and leanness of power grid management.  A communication network system covering all aspects of the power grid will be formed to realize functions such as power grid data management, comprehensive supervision of information operation and maintenance, power grid spatial information services, and production and dispatch application integration, and fully realize the informatization and leanness of power grid management.  Eighth, give full play to the value-added service potential of power grid infrastructure.  While providing electricity, it serves the country's "Three Networks Integration" strategy, provides users with various integrated services, provides platform support for the informatization and interaction of water supply, heating, gas and other industries, and expands and enhances the value-added services of power grid infrastructure.  scope and capabilities to effectively promote the development of smart cities.  Ninth, promote the rapid development of power grid-related industries.  The electric power industry is a capital-intensive and technology-intensive industry with large investments and long industrial chains.Features.  The construction of smart grids will help promote the technological upgrading of equipment manufacturing, communications and information industries, and lay the foundation for my country to occupy the commanding heights of the world's power equipment manufacturing field.  I still say that green energy-saving awareness will become the mainstream of the world, so smart grids will also promote the world's economic and social development. It mainly plays an important role in responding to global climate change and promoting the sustainable development of the world's economy and society.  It is mainly manifested in: First, promote the development and utilization of clean energy, reduce greenhouse gas emissions, and promote the development of low-carbon economy.  Second, optimize the energy structure, realize the complementarity of various energy forms, and ensure the safety and stability of energy supply.  Third, effectively improve the efficiency of energy transmission and use, and enhance the safety, reliability and flexibility of power grid operations.  Fourth, promote technological innovation in related fields, promote technological upgrading in equipment manufacturing and information communications and other industries, expand employment, and promote sustainable social and economic development.  Fifth, realize two-way interaction between the power grid and users, innovate the traditional model of power services, provide users with better and more convenient services, and improve people's quality of life.  It is no exaggeration to say that the interactive power grid is not only the basic model of the next generation global power grid, but also the core of China's power grid modernization.  In fact, the essence of interactive power grid is energy substitution, compatible utilization and interactive economy.  Technically speaking, the interactive power grid should be the integration of the most advanced communications, IT, energy, new materials, sensors and other industries. It is also an integration of distribution network technology, network technology, communication technology, sensor technology, power electronics technology, and energy storage technology.  Synthesis has a direct comprehensive effect on promoting new technology innovation.  Therefore, smart grid has the characteristics of reliability, self-healing, economy, compatibility, integration and security.  I believe that the essence of the interactive grid theory is to use the creative standards and technical means of information technology to promote the innovation and upgrading of the power grid system, the most important asset of the industrial world, on a large scale, and to establish the interaction between consumers and power grid managers.  .  "(To be continued.
