Recently, the State Grid Corporation of China announced the construction plan of a strong smart grid in the next 10 years in the form of Document No. 1. The plan proposes that by 2020, China will basically build a strong smart grid.
According to sources, a Sino-US smart grid research project is being promoted by the Energy Research Institute of the National Development and Reform Commission. Unlike the strong smart grid of the National Grid, which focuses more on UHV transmission, the project focuses on the demand-side smart grid construction with clean, efficient, and distributed core.
The above situation shows that the construction route of the smart grid is still in dispute.
Two kinds of schemes have been proposed. At present, there are two kinds of schemes for the construction of smart grids. One is a unified and strong smart grid with long-distance and large-capacity transmission as the main features, and the other is based on clean, efficient, and distributed intelligence. For the power grid, the former emphasizes transmission, while the latter emphasizes power distribution, and the State Grid Corporation has been pushing for a strong smart grid.
Liu Xinfang, deputy director of the Information Department of the State Grid Corporation’s External Contact Department, stated that the goal of the State Grid Corporation of China is to basically build a strong smart grid by 2020, and form a UHV synchronous network in North China, East China, and Central China as the receiver, and use the northeast and northwest grids. For the delivery end, it is connected with the strong grid structure of major coal, hydropower, nuclear power and renewable energy power generation bases throughout the country.
Previously, Shu Yinhao, deputy general manager of the State Grid Corporation of China, once stated that China’s smart grid is a “strong grid†first, and UHV power grids with long-distance and large-capacity transmission characteristics will become the core link. This is the stage of economic development in China. Energy distribution is determined by the characteristics.
It is learned from other places that the construction of UHV transmission projects is also the focus of China Southern Power Grid Corporation.
Although the construction of UHV transmission projects has become the focus of power grid construction for the two major power grid companies, Liu Xinfang stated that the most important thing for smart grid construction is to obtain government support.
“The government may be more inclined to build a clean, efficient, distributed smart grid that focuses on the demand side.†Industry sources told reporters that the China-US smart grid research project involving the Energy Research Institute of the National Development and Reform Commission is an example. Zhang Guobao, deputy director of the National Development and Reform Commission and director of the National Energy Administration, once said that “we think that the smart grid should be a clean, efficient, distributed grid, but there are also different opinionsâ€.
Based on reality and eyeing the future From the current point of view, the industry is still controversial about the construction of smart grids characterized by long-distance and large-capacity transmission. There are good reasons for the proposal of two schemes for smart grid construction.
"The most typical is the current power shortage." Liu Xinfang introduced that as China's economy recovers, the demand for electricity continues to rise. The Central China Power Grid has 3 million kilowatts of electricity, but the Northwest Power Grid has a surplus of 10 million kilowatts, but the current grid cannot be transferred to the northwest. The surplus power of the grid is sent to the Central China Power Grid, which requires UHV transmission.
Liu Xinfang said that if a strong smart grid is built, power transmission between the Northwest Power Grid and Central China Power Grid will no longer be a problem. By building a UHV transmission line in a strong smart grid, electricity from the Northwest Grid can be transported to Central China Power Grid at a low cost. “In this way, companies do not have to worry about power shortages when orders increase.â€
"Of course, this is also beneficial to the State Grid Corporation." Liu Xinfang said that if the surplus power of the Northwest Grid can not afford to use, you need the power grid to pay the bill. However, Huazhong Power Grid could have sold more electricity but no electricity could be sold.
However, not everyone agrees to build a strong smart grid with UHV transmission as its core. Wu Jiandong, head of the smart energy research group at the China International Economic Exchange Center, proposed that the U.S. ultra-high voltage transmission network should be replaced by an intelligent superconducting network. Wu Jiandong believes that the infrastructure and equipment manufacturing capabilities of transformers in the power industry in China have an intelligent material basis.
Wu Jiandong said that the initial investment in the implementation of smart grid reform in China only needs 300 billion to 500 billion yuan, and it also has a huge boost for transformers, smart terminals, and network management technologies. It can at least raise the national economy by 1-2 percentage points each year. If we focus on the construction of an interactive power grid from now on, the benefits will be enormous. If we expand the scale of investment, China will likely become the country that dominates the global interactive power grid. “The government may be more inclined to build a clean, efficient, distributed smart grid that focuses on the demand side.†Industry sources told reporters that the China-US smart grid research project involving the Energy Research Institute of the National Development and Reform Commission is an example.
