"Twelfth Five-Year" Accelerates the Construction of Smart Grid

The China Electric Power Enterprise Federation recently released the "Survey of the 12th Five-Year Plan" Rolling Research Report of the Electric Power Industry ("Report"). The "Report" stated that during the "12th Five-Year Plan" period, it is necessary to speed up the construction of a smart grid, build a large-scale power supply base, and construct a strong grid. On the basis of the UHV AC pilot demonstration project, we will focus on accelerating the construction of UHV AC synchronous power grids in North China, East China and Central China.

Accelerating the Construction of a Strong Smart Grid According to the “Report”, it is expected that by 2020, China will build a UHV synchronous network in North China, East China and Central China as its center, a Northeast UHV power grid and a 750 kV Northwest power grid as the delivery end, linking major coal-fired power plants. , hydropower, nuclear power, renewable energy bases, strong and coordinated smart grids at all levels of the power grid.

The development of China's power grid intelligence is based on a strong grid, including the power system of power generation, transmission, transformation, distribution, electricity and scheduling six major areas, covering all voltage levels, to achieve "power flow, information flow, The high integration of business flows.

Among them, the UHV synchronous grid in North China, East China and Central China will form the main grid of “five vertical and six horizontal”. Northwest China Power Grid, as an important sending end power grid, has achieved close contact with North China, East China and Central China UHV power grids through DC projects on the basis of the existing 750 kV power grid structure during the “Twelfth Five-Year Plan” period.

It is reported that the Qinghai-Tibet network project that was completed and put into operation last year satisfied the power supply in Tibet and achieved the networking of the Tibet Power Grid and the northwestern main network.

In the construction of a strong smart grid, CEC emphasized that during the “Twelfth Five-Year Plan” period, it is necessary to focus on strengthening technical innovation and pilot application, and on the basis of systematically summarizing and evaluating the smart grid pilot project, accelerating the revision and improvement of relevant standards. Promote smart grid project construction. Strive to the end of the "Twelfth Five-Year Plan", China's smart grid technology and key equipment to achieve a major breakthrough in the intelligent standards system is basically complete, the power grid to achieve a higher level of intelligence.

At the same time, CEC suggested that the smart grid should be formally incorporated into the national development strategy and given policy and financial support, and accelerate the formulation and improvement of new energy, UHV grid, smart grid and other technical standards, and promote the intelligent construction of the power system.

Deepening the reform of the power system Under the circumstance of considering the rise in coal prices, making up for historical debts, and a 8% return on net assets of power companies, the reasonable average sales price in 2015 should be 728.7 yuan/kwh, which is an increase of 157.5 yuan/year from 2010/ Thousands of kilowatt-hours, an increase of 27.6%, an average annual increase of 5.0%.

In order to achieve the above objectives, ensure the economical efficiency of the power industry planning and achieve the “12th Five-Year Plan” target of the power industry, CEC stated that it is necessary to deepen the reform of the power system, strengthen the construction of the power market system, and improve the system of laws and regulations. Specifically, efforts should be increased from the following aspects:

Strengthen the unified planning of the power industry and establish a scientific power planning management mechanism. Establish and improve the government's power planning management system, and establish a plan to report, approve and publish systems in accordance with law. Improve the research and cooperation system of power planning and rolling adjustment mechanism.

Optimize the layout of power supply structure, promote the development of green power supply and improve the ecological environment. Emphasis on hydropower migration and environmental protection work, and promote the start of a number of large and medium-sized hydropower projects as soon as possible; unify the nuclear power technology route, open nuclear power investment market. Strengthen the unified planning of wind power, promote the absorption of wind power, support the industrialization of wind power, solar energy and other renewable energy power generation, and increase the level of technical equipment. Optimize coal and electricity layout and actively promote the integration of coal and electricity.

Reform and improve the pre-management mechanism of power projects. Standardize pre-work procedures and implement project owners' market bidding system and project filing system.

Appropriately raise the price level, and use economic adjustment measures to promote energy conservation and emission reduction. Strict energy conservation and emission reduction standards have been formulated, business models for energy conservation and emission reduction have been nurtured, and innovation and promotion of energy saving and emission reduction technologies have been promoted.

Strengthen the building of technological innovation capabilities and promote the upgrading of power equipment and industrial technologies. Focus on the integration and effective use of industry scientific and technological resources. The introduction of major equipment demonstration project (first set) encouragement policy. We attach great importance to and actively support the basic research of power equipment.
