Liu Zhenya, general manager of State Grid Corporation of China, said recently that the company plans to invest 250 billion U.S. dollars (approximately 1.6 trillion yuan) in the next five years to build a strong smart grid in China; by 2020, it will form five vertical and six horizontal UHV transmission lines. Backbone grid, built a strong smart grid.
At the same time, he also stated that the country is vigorously promoting emerging strategic industries such as new energy and electric vehicles, and they have imposed higher requirements on the power grid. How to achieve synergies among various industries, the smart grid has become a node in the development of many industries.
"By 2015, the national grid's resource allocation capabilities, security support capabilities, and public service capabilities will be fully enhanced. It will be able to meet the needs of 260 million kilowatts of electricity in a wide range of optimal configurations and support 90 million kilowatts of wind power and 8 million kilowatts of solar power. Intake and consumption, guarantee the application of 800,000 electric vehicles, and realize automatic collection of all customers' electricity consumption information. In the next five years, the national grid will invest 1.5 trillion yuan for power grid construction, and create a highly intelligent transmission and distribution In the network, 6,100 smart substations with 110 kV and above are built; more than 2,950 electric vehicle charging and replacement stations and 540,000 charging stations are newly built, and 230 million smart meters are installed. Also, the strong smart grid is a complete intelligent power system. Power generation, transmission, substation, distribution, electricity, dispatch, and all other voltage levels, and the development of each link must be closely linked and coordinated with each other, and the overall functions and advantages can be fully utilized.
He said smart grids can increase acceptance of new energy sources. It is estimated that by 2020, the entire society will use more than 8.3 trillion kWh of electricity, with an installed capacity of more than 1.8 billion kilowatts, of which wind power and solar wind capacity will reach 160 million kilowatts and 24 million kilowatts, respectively, and the national cross-regional power flow will exceed 4 Billion kilowatts. "In order to meet the needs of the rapid development of new energy, and effectively solve the problems of scale-connected wind power, distributed access to photovoltaic power generation, and joint operations of wind and solar energy storage and transportation, we must vigorously develop a smart grid."
Therefore, the power grid will integrate advanced transmission technologies such as UHV, modern information technologies such as the Internet of Things, and high-performance computing and control technologies such as cloud computing. It will be closely integrated with telecommunications networks, radio and television networks, and the Internet to become powerful and widely connected. Smart service system.
