How important for photovoltaic photovoltaic agricultural "13th Five-Year"?

Time:2017-08-253Publisher:Browse:18second

The problem of photovoltaic scale agricultural development is not solved, the photovoltaic "13th Five-Year" planning objectives will be difficult to achieve. Re examining the photovoltaic agriculture is not only a quantity problem, but also a quality problem.
The national development plan of the "13th Five-Year" photovoltaic power plant construction target is 150GW, the construction of photovoltaic power plant growth rate was 436%. Compared with other renewable energy "13th Five-Year" power plant construction target of two digit growth, an increase of 436% is the highest, the PV exciting.
But please wait for photovoltaic power station construction target of "13th Five-Year" cheers, because it is likely to do.
China's PV is always surprising. Over the past more than 10 years, the photovoltaic industry has gone from scratch, from the world to the first; over the past four years, the construction of photovoltaic power plants from scratch, from there to the world's first. But two years ago, there was another accident.
This accident is, before 2013, the construction of photovoltaic power station results are always beyond expectations than expected, and after 2014, photovoltaic power plant construction results are always unexpected, lower than the planned goal. 2014 plans to complete the 15GW, the actual completion of 10.6GW; 2015 plans to complete the 23.1GW, the actual completion of 15.1GW. There are many reasons for this accident, and the development of photovoltaic agriculture is not ideal. It must be one of the important reasons. The problem of photovoltaic agricultural scale development is not solved, it will eventually become the development of photovoltaic effect "13th Five-Year" plan, and the impact of China's energy supply structure of the most important factors.
This is because the distributed photovoltaic power station is an important part of photovoltaic development "13th Five-Year" plan, and agriculture is also an important part of photovoltaic distributed photovoltaic power plant. The problem of photovoltaic scale agricultural development is not solved, the development of distributed PV target is difficult to achieve, "13th Five-Year" photovoltaic "13th Five-Year" planning goals more difficult to achieve, the rationalization of the structure of energy supply in China will encounter obstacles.
So, should stand in the "13th Five-Year" photovoltaic development plan is completed, China's future energy supply rational perspective, re-examine the PV agriculture, this is not only a number of problems, it is a quality problem. At present, some problems need to be solved in the large-scale development of photovoltaic agriculture:
1., distribution has become the main reason for the annual construction goals of photovoltaic power plants in the past can not be achieved
In 2014 the construction of distributed photovoltaic power plants is 15GW, the actual completion of 10.6GW, which distributed target is 8GW, the actual completed only 2GW; 2015 national photovoltaic power station construction target is 23.1GW, the actual completion of 15.1GW, which distributed not set goals, to encourage the development, the actual completed only 2GW. The actual construction results of the distributed PV power station have seriously affected the completion of the annual construction target of the national photovoltaic power station.
The reasons for the unsatisfactory results of the construction of distributed PV power stations deserve careful study. Over the past two years, the state of distributed photovoltaic power plants and some never seriously, never have policy preference, although you can predict the distributed construction result is not good, but the actual construction result is always the prediction result is worse than. This force we must seriously consider the "13th Five-Year" photovoltaic development plan forthcoming, how to locate the distributed PV? How to develop distributed PV?
2. must be an important part of distributed PV development "13th Five-Year" plan

This force we must seriously consider the "13th Five-Year" photovoltaic development plan forthcoming, how to locate the distributed PV? How to develop distributed PV?
2. must be an important part of distributed PV development "13th Five-Year" plan
In the development of photovoltaic "13th Five-Year" planning discussion, there are two important indexes: one is the construction of photovoltaic power plants is 150GW, which is distributed 70GW; one is the western region accounted for new solar power installed capacity of 35%, the other 65% are distributed in the eastern region. People often remember only the first one and ignore the second.
The connotation of these two indicators are the same, is the indispensable content of PV "13th Five-Year" plan, two data quantity cannot be reduced, must be achieved at the same time. This is decided by two reasons:
First, the reverse distribution pattern of China's energy resources is determined. In the Chinese development scale photovoltaic power generation, there are three options: first, in the solar energy resources and land rich western construction of large-scale photovoltaic power plants, photovoltaic power generation will be large-scale, long-distance transmission to the power load center to the East, the result is bound to transport capacity limited, transport costs are too high, and this is not necessarily the best choice; second, the most abundant solar energy resources, but not in the power load center east construction of large-scale photovoltaic power plants, although does not require large-scale, long-distance transmission, the result will inevitably face serious shortage of available land, that may not be the best choice; third, in the eastern part of the large-scale development of distributed photovoltaic power plants, will undoubtedly become the best choice that must be the choice. Similarly, it has also become a PV development "13th Five-Year" to plan the best choice, must choose.
Another reason is the coming era of energy democratization.  Distributed power of self occupied, NDF is undoubtedly the most reasonable energy use patterns, the rapid development of smart grid, energy storage technology, which makes the energy of democracy is possible. Compared to all other forms of energy use, only photovoltaic power generation has the standard form of distributed power and the most economical use form, and it is the main direction of human energy usage. Similarly, it should be to allow all doubt PV development "13th Five-Year" planning is an important and indispensable content.
3., photovoltaic agriculture should become an important component of distributed PV
The connotation of distributed photovoltaic power plant: is located near the user, the power can be used locally, at 10 thousand volts and the voltage level of the grid, power generation projects and individual and outlets does not exceed the total installed capacity of 6 MW; extension of distributed photovoltaic power plant: mainly by the roof power station (residential and commercial) and photovoltaic agriculture two most.
Photovoltaic agriculture should be the most important component of the distributed PV power station. This is because only the development of photovoltaic agriculture, to complete the development of distributed PV "13th Five-Year" in the planning of construction target.
   By the end of 2015, China has built 5.7GW distributed photovoltaic power plants, construction of 70GW distributed PV development goal planning according to the "13th Five-Year", the next five years, the annual construction quantity of not less than 12GW. For photovoltaic "13th Five-Year" plan will be how to constitute a distributed target, how to realize the problem, say, how to pose a problem even will decide whether to realize.
Our past experience has proved the development of distributed PV, must get rid of relying mainly on "13th Five-Year" plan on the roof to complete the remaining 62.3GW distributed photovoltaic power plant construction goal, achieve reasonable future energy supply mechanism of fantasy. It is determined by the large population, the scarcity of land available, the limited roof of buildings and the complex property rights problem. Moreover, not only are the existing roofs difficult to meet the needs of the construction of distributed PV power stations in our country, but it is impossible to meet the needs of the rational distribution of PV power in the future.
Since the roof can not realize the PV development "13th Five-Year" China's energy supply planning and reasonable structure, it must be another extension to re-examine and positioning of distributed PV agriculture. On the basis of scientific and reasonable policy guidance, photovoltaic agriculture should become an important component of China's distributed pv.
4., photovoltaic agriculture has become an important part of the distribution
The connotation of photovoltaic Agriculture: refers to the establishment of agricultural facilities or general agricultural land, does not change the nature of land, and promote the comprehensive development of agriculture and photovoltaic industry photoelectric and agricultural composite system.
The extension of photovoltaic agriculture mainly includes agriculture (planting, breeding), greenhouse, agriculture and light complementary, fishing and light complementary, and Lin Guang complementary. The extension of agricultural light complementary in the agricultural field through scientific and reasonable to raise support or support the flexible photovoltaic photovoltaic approach, a form of foundation of the farming and photovoltaic power generation does not change in the fair value of the two sides combined.
In our country already completed 5.7GW distributed photovoltaic power station digital, the PV agriculture has become the important content of the distributed PV actually. If a little attention, a large number of news and cases about the development of distributed PV, a large part of all related to photovoltaic agriculture. A large number of distributed photovoltaic training in the content and cases are also all related to photovoltaic agriculture.
Zhejiang provincial development and Reform Commission recently "Zhejiang agricultural light complementary type ground photovoltaic power station construction achievements, problems and Countermeasures of" the article said: "at the end of March 2016, Zhejiang province has built a network of ground photovoltaic power plant 20, the total size of 672 thousand kilowatts, including the eastern provinces of the largest single country CHINT 200 MW light complementary agricultural ground photovoltaic power plant; built in 14, the total size of 647 thousand kilowatts; 2016 is expected to be completed by the end of the ground more than 2 million kilowatts of photovoltaic power station. The ground photovoltaic power station adopts the mode of "agriculture and light complementary", "fishing light complementary", "forest light complementary" and so on, and has multiple economic and social benefits." And known by the end of 2015, Zhejiang has built a total of photovoltaic power plants only 1.64GW.
5., the current policy is not clear, photovoltaic agriculture is difficult to scale development
At present, the overall attitude of the country towards the development of photovoltaic agriculture is positive. However, or by the photovoltaic industry management department of agriculture involves more influence, inevitably each department acting on its own. Or affected by different angles of cognition, it is inevitable that the relevant policies are unclear. There are three aspects: in the energy management department, the "notice" national energy board on the further implementation of distributed PV relevant policies put forward clearly "encourage distributed photovoltaic power generation and farmers poverty alleviation, new rural construction, agricultural facilities combined, promote rural residents and improve the development of agriculture and rural areas"; in the land management department, the Ministry of land and resources "development and Reform Commission, the Ministry of science and technology, Ministry of information industry and the Ministry of housing and urban construction ministry of Commerce on supporting the development of new formats of new industry to promote innovation and public entrepreneurship peoples land views" clearly on the construction of occupied agricultural land, all the land shall be part of the land management by construction; in agricultural management departments, it is understood that support and oppose the two different opinions exist at the same time, the current wait-and-see and does not participate in the state. All this makes the development of photovoltaic agriculture, especially agriculture and light complementary, in a dilemma.
Careful introduction of photovoltaic agriculture policy is correct.  One is because "one billion and eight hundred million mu of arable land" which is a national strategic issue not discussed; the two is that agricultural planting and photovoltaic power generation with good, two benefits were not affected, with well, two benefits are affected. Three, because in photovoltaic agriculture, the business model of concern is still in the process of maturity.
However, in order to complete the "13th Five-Year" planning of distributed PV short-term development targets and reasonable structure of energy supply and long-term development goals, the status of agriculture is also the problem of PV to have time to discuss and solve as soon as possible, especially agricultural light complementary problems. This is because agriculture, greenhouse, fishing, light complementary, forest and light complementary, the space available for development and utilization is limited, agriculture, light complementary, space for development and utilization is enormous.
Photovoltaic agricultural is agricultural land scarce countries to create a combination of agricultural development and the development of photovoltaic power generation, is the cause of human development in a photovoltaic not passive choice has, it is the only value of full use of land resources. Therefore, stressed that our country should vigorously develop photovoltaic agriculture, especially agriculture and light complementary logic is: This is certainly not the best choice, but it is likely to be a must.
