On August 10, U.S. President Barack Obama announced the construction of a new smart electricity that can realize the transmission of electricity between the East and West banks. National Power Corporation (hereinafter referred to as "national power") officially responded to this new power development strategy yesterday. The head of the relevant department of the company disclosed to CBN that national power and the U.S. energy department are expected to further cooperate in the field of electric intelligence and large power

smart electricity standards are expected to be issued

in April, when meeting the national electricity delegation in the United States, U.S. Secretary of Energy Steven Chu said that China and the United States have many areas in which they can learn from each other in the development of renewable energy and transmission and distribution. In the future, the United States also needs higher voltage levels of electricity and technology, and hopes that the two sides can have more and more in-depth exchanges and cooperation in the development of energy and electricity. On July 16, U.S. Secretary of Commerce Gary Locke also said during his visit to Guodian that the U.S. side very much agrees with the goals and principles of unified standards, strengthened planning, based on information technology and focusing on interaction put forward by Guodian in the process of developing smart electricity. He expects that Guodian can continue to play a leading role in these areas, but its performance is weaker. He hopes that China and the United States can strengthen cooperation and realize technology sharing

the most important problem of smart electricity is to successfully define the basic architecture of the next generation of electricity, and turn the electric system that operates more than one million kilometers into an interactive electric system. Wu Jiandong, a professor of the Chinese Academy of Sciences and a famous energy expert, believes that "if possible, it will become an intercontinental network in the future. The power optical fiber composite cable electricity will replace the traditional metal cable electricity, and its task is to promote the power enterprises to transform from medium and low-end power providers to integrated energy, communication and service providers."

"China US energy cooperation in the future will mainly focus on three aspects: carbon capture and storage, green building, and smart electricity and electric vehicle cooperation." Wu Jiandong said, "it is estimated that in the next step, the two sides will conduct a consultation on the establishment of new standards for electricity. This is the first time that China has participated in the formulation of international standards, especially smart electricity standards, as a major country in the history of world electricians."

in fact, "unless the large power mode is adopted, China mainly relies on UHV for long-distance transmission between the East and west sides of the United States." Hu Zhaoguang, vice president of Beijing Economic and Technological Research Institute, said. On February 11 this year, the U.S. Senate and house of Representatives passed the 2009 recovery and Reinvestment Act to stimulate the U.S. economy, with a total budget of $789billion, of which $4.5 billion was used to transform smart electricity. Obama's latest speech obviously improved this investment plan, "such as the construction of large power stations across the central and western United States, it will be a huge investment." Hu Zhaoguang said. Lu Qiang, an academician of the Chinese Academy of Sciences and a professor of the Department of electrical engineering at Tsinghua University, made a rough estimate of the investment in smart electricity in China, "to reach the international advanced level, the total investment in the three stages will exceed 1trillion yuan."

China's smart electricity may be built ahead of schedule

first of all, realize the efficient and safe recycling of single category low value-added waste

Ge Zhengxiang, director of the Research Office of State Grid Corporation, previously told CBN that State Grid Corporation has established the three-step principle of smart electricity. The first period is from 2009 to 2010, which is called the planning pilot stage, The six eligible "white list" enterprises have been announced to strengthen the development planning of smart electricity, formulate technical and management standards, carry out key technology research and development and equipment development, and carry out pilot work in all links

"the period from 2011 to 2015 is the stage of comprehensive construction. We will accelerate the construction of UHV and urban and rural power distribution, initially form an intelligent power operation control and interactive service system, and achieve major breakthroughs and wide applications in key technologies and equipment." Ge Zhengxiang said, "from 2016 to 2020, a unified strong smart electricity will be built in an all-round way, and the technology and equipment will fully reach the international advanced level."

Hu Zhaoguang believes that if the technology develops faster, China's smart electricity may be completed ahead of schedule. "China has solved many technical problems at present, and the key is that the central government should raise the plan to the height of the national energy strategy. Smart electricity is good for the formulation of electricity standards in the future."

this is basically the same as Wu Jiandong's idea. Wu Jiandong said that China has many advantages in electric technology. "However, in terms of optimizing the allocation of power resources nationwide, with such an innovative system, we also need to learn from advanced countries, carry out continuous technological innovation, and strive to become a big and powerful country in the world of smart electricity." Wu Jiandong said

however, the development of smart electricity in China still faces many challenges. Wu Jiandong believes that building smart interactive electricity is unprecedented and a thorough transformation of the world's power system for more than 100 years. First of all, we should solve the problems of integration, communication, internationalization and substitution and compatibility of main energy sources. "At the same time, we should realize the modernization and systematization of centralized energy and distributed energy management, as well as the practicality of energy storage technology." At the same time, Wu Jiandong said, "there are also two important aspects, namely, to realize the selection and optimization of electric upgrading chip technology and compatible standards and the high-end management of electric system."
