The guiding opinions on energy work in 2018 (hereinafter referred to as the “opinions”) issued by the National Energy Administration pointed out that this year, we will continue to optimize the layout and structure of the main grid, carry out in-depth demonstration of the national synchronous grid pattern, promote the construction and transformation of distribution networks and smart grids, and improve the operation efficiency, safety and reliability of power grids.

The guiding opinions on energy work in 2018 (hereinafter referred to as the “opinions”) issued by the National Energy Administration pointed out that this year, we will continue to optimize the layout and structure of the main grid, carry out in-depth demonstration of the national synchronous power grid pattern, study and implement the inter provincial strengthening scheme in Central China, strengthen the inter provincial power grid mutual assistance capacity in the region, promote the construction and transformation of distribution network and smart grid, and improve the power grid operation efficiency, safety and reliability. According to the implementation of the target market, accelerate the construction of hydropower transmission channels in Southwest China, steadily promote the construction of power transmission channels across provinces and regions, and promote the preliminary work of power transmission channels in Xinjiang, Qinghai, Sichuan, Shaanxi and other regions.

As we all know, the synchronous power grid is mainly realized through AC networking. Due to the prominent characteristics of “strong direct and weak AC” of UHV in China, the “in-depth demonstration of the national synchronous power grid pattern” mentioned in the opinions indicates that the UHV AC project in China will be accelerated to some extent. At the same time, the opinions pointed out that the inter provincial strengthening program in Central China should be studied and implemented to strengthen the mutual assistance capacity of inter provincial power grids in the region. It can be seen that the central China UHV AC loop network hotly discussed by the two sessions is one of the important choices to improve the inter provincial liaison capacity of central China power grid.

At the same time, with regard to UHV DC, the opinions made it clear that within this year, it is planned to build such transmission channels as Inner Mongolia Shanghai Miao Shandong Linyi ± 800 kV HVDC and Xinjiang Zhundong East China Southern Anhui ± 1100 kV HVDC, with an additional transmission capacity of 22million kW. We will solidly promote the approval and construction of qualified projects, and strive to start the construction of Zhangbei flexible DC test demonstration project, Wudongde power transmission Guangdong Guangxi flexible DC, Sichuan Hydropower transmission fourth circuit DC and other transmission channels in. In addition, Shaanxi, Qinghai, Xinjiang, Longbin, Baihetan Hydropower, hydropower and power transmission channels in the upper reaches of the Jinsha River, and the preliminary demonstration of the Fujian Guangdong networking project were solidly promoted.

Up to now, the Zhangbei flexible DC test demonstration project has been started on February 28, and the Shanghai Miao Linyi UHV DC has been completed. As for Fujian Guangdong networking and other projects, shuyinbiao, chairman of the State Grid Corporation of China, said in an interview with the reporter of China Energy News: “the State Grid is promoting the networking of Fujian and Guangdong; it is suggested to approve the Sichuan Jiangxi UHV DC project as soon as possible; and promote the Qinghai Henan UHV DC project, which is ready to start this year.”

At the same time, in promoting the transformation and upgrading of rural power grids and energy poverty alleviation in poor areas, the opinions revealed that China will focus on poor areas, especially the “three districts and three prefectures” deep poverty-stricken areas, as well as the key counties of the national poverty alleviation and development work, concentrated contiguous poverty-stricken areas and revolutionary old areas, and deeply implement the transformation and upgrading of rural power grids. Focus on deep poverty-stricken areas, carry out in-depth poverty alleviation, do a good job in targeted energy poverty alleviation and counterpart support, implement the “13th five year plan” for photovoltaic poverty alleviation, strengthen the management of photovoltaic poverty alleviation projects, and ensure that photovoltaic poverty alleviation work is carried out steadily and orderly.

In addition, in terms of expanding international energy cooperation and ensuring national energy security, the opinions clearly stated that China will actively implement the “global energy Internet” initiative and promote interconnection with the power grids of surrounding countries.
