In June 19th, the National Energy Bureau's Comprehensive Division issued an emergency notice of the National Energy Bureau's comprehensive division on photovoltaic power generation. It was reflected that some power grid enterprises stopped the related work, such as the grid connection of the distributed photovoltaic power generation, the record and the subsidy cushion, on the basis of the notice on the related matters of photovoltaic power generation in 2018. Do.


The emergency notice of the State Energy Bureau's comprehensive division requires that all local and local power grid enterprises should continue to do a good job of grid connected, (generation) records and local subsidy advances according to the law, and not to stop the project without the scale of the state subsidy construction. The dispatched energy regulatory agencies should strengthen supervision over the power grid enterprises and find problems to be corrected in time.


Photovoltaic power generation is a green and clean energy, which is in line with the direction of energy transformation and development, and plays an important role in the energy revolution. In recent years, China's photovoltaic development has made remarkable achievements. China's photovoltaic power generation installed in 5 consecutive years the world's first, the total installed capacity of 3 consecutive years ranked first in the world. Photovoltaic technology is constantly innovating and breaking through, leading the world, and has formed a complete photovoltaic industry chain with international competitiveness. Especially in the last two years, the new production has reached 34 million 240 thousand, 53 million 60 thousand kilowatts, and the installed capacity of the grid is more than 130 million kilowatts at the end of 2017. Photovoltaic power plays an important role in promoting the energy transformation.


The national development and Reform Commission, the Ministry of Finance and the State Energy Bureau jointly issued the notice on matters related to photovoltaic power generation in 2018. The move has caused widespread concern in the market. According to the previous state energy bureau's new energy department and the State Development and Reform Commission's price department, the person in charge answered the statement, one of the background of the announcement about the related matters of photovoltaic power generation in 2018 is that with the rapid development of the photovoltaic market, the photovoltaic market has the problem of photovoltaic power generation and the demand for subsidies. Further expansion and other issues directly affect the healthy and orderly development of the photovoltaic industry. We need to adjust our development ideas and improve the development policy according to the new situation and new requirements.


In recent years, the problem of photovoltaic power generation in China has been attracting much attention. What good measures will be taken to solve the problem of abandoning light and limiting electricity in the future? How can we solve this problem from the source?


Zhao Ying, director of the photovoltaic special committee of the China Renewable Energy Society, believes that the abandoning of light is caused by a variety of reasons, the most important reason is that the development of photovoltaic power generation is very fast, and the power grid is not well matched. The two need to coordinate well development, solve the problems of smart grid and micro grid, and do well in the planning of national renewable energy power generation.


Zhao Ying said that the state now actively encourages distributed generation, especially in the eastern region. Geography and terrain determine the Western solar resources are very good but less electricity, and the eastern use is very much, but the large-scale power plant is very few, so the development of distributed generation is a very good solution.


In Zhao Ying's view, the distributed generation is a good way to learn from the experience of Europe, especially the European countries. For example, hydrogen is one of the future energy sources. To make hydrogen, one of the most effective ways is to make hydrogen in the light of solar energy, or to make hydrogen from solar cells, which can solve the problem of lighting up. Under the condition that conventional power grids can not be solved, hydrogen transport can be used.


Zhao Ying suggested that the solution of the problem of light up, on the one hand, should be solved from the point of view of national strategic planning, which is the fundamental way; on the other hand, we should explore the use of solar power, which is an effective way to eliminate the light.


As a network hub linking energy production and consumption, the power grid plays a vital role in the efficient development and utilization of renewable energy.


For the problem of abandoning light, Zhang Dong, Deputy Secretary General of the Special Committee on power generation and power integration of the Renewable Energy Society of China, believes that the first is the problem of power supply structure. China is a big fossil energy country with coal as the main power. Unlike in the United States, the proportion of natural gas in our country is relatively small, the proportion of the pumping station is relatively low, the scenery resources in the northwest region are relatively good, and the proportion of installation is relatively high. The State Energy Agency has issued a series of documents to develop distributed power generation in the East and central regions. Many new installations are in the central and central regions, plus the rebound in electricity consumption this year, so the situation in the first half of this year has improved.


Secondly, apart from the uncoordinated development of power supply and power grid, there is also a lack of market mechanism. All provinces and municipalities have been formulated at the beginning of the year. The space for dispatching and Optimization for the power grid is very small, and it is also restricted by the assessment mechanism. So there are many problems in the absence of transmission policies and mechanisms in the cross province.


Zhang Dong said that, in view of the related problems existing in the grid, we hope that industry experts will find a good way to promote the development of photovoltaic power grid together through collaborative development of large power grid and the development of distributed energy Internet.
