Polaris solar PV net news: Golmud PV is located in the hinterland of the Qaidam Basin, Qinghai-Tibet plateau, this stretch of desert wasteland in saline-alkali soil more than 3,000 meters above sea level, its remote location, harsh climatic conditions, sand-dust weather is frequent, but it is one of the most national exposure, but also the development of photovoltaic, solar thermal and solar industry best.
In recent years, Golmud city, Qinghai province, PV industry the rapid rise to become the focus of the country and the world PV industry. However, subject to network conditions, abandon light pain also affects the development of the power industry in Golmud.
“PV” lights up the Gobi desert
On the plane in Xining to Golmud, when over the flights to Golmud city, looked out from the plane, a piece of dark blue poly-silicon panels, as if even the flocks of Blue Lake, yellow Gobi desert suddenly comes alive.
“This is our Golmud photovoltaic power plant. “Datang Golmud of Qinghai PV power station Li Jianjun told the China Economic Herald reporter,” Golmud on December 21, 2011 with a grid-connected PV power station power generation, the total installed capacity of 20MW. Phase II December 27, 2012, grid-connected, total installed capacity 22MW. On January 25, 2016 grid in three phases, installed capacity of 50MW. ”
Drive arrived at the photovoltaic field, reporters saw pieces of polycrystalline silicon is like a sunflower, keeping the same angle, looking at the blue sky, Sunshine as much as in the “face” for the nearby grid green energy.
According to Li Jianjun introduction: “development of photovoltaic solar energy has two natural advantage here: the Sun and the Earth. “According to the introduction, Golmud is solar energy resource development in the country overall one of the most competitive regions, with an average annual sunshine time of 3096.3 hours, total annual radiation dose of 6950 MJ/m², is worthy of the” solar city “. In addition, desertification in Golmud with lots of unused State-owned land, area area of 124,500 square kilometers, unused land area of nearly 62,000 square kilometres, reserves of up to 1.55 billion kilowatts of solar power theory.
Reporters on the scene saw, Gobi desert saline-alkali soil there is no green vegetation, plant grown gesanghua became the Highland station the only embellishment. Because there is no green vegetation, Golmud than some of the higher elevations of 2800 meters above sea level altitude less oxygen, conditions have become more difficult.
Datang Golmud PV total of 9 staff, in order to let employees alone, deliberately keeps a dog in the station. 9 young people and a dog stand plateau PV story together, becoming a much-told story in Datang company.
Reporters in the interview that, Golmud has relied on the Qinghai-Tibet Highway and the development of Qaidam resources, long-term and extensive development, air and brought risks of heavy metal pollution, industrial waste disposal problems. Golmud was hit the “lack of economic development and environmental protection cannot” awkwardness.
In recent years, the Golmud large-scale development and utilization of solar and other renewable resources, change the extensive development pattern, take the road of recycling economy, transition of exploring ecological protection and economic development. According to requirements of the national and provincial new energy industries, State development, Golmud to the new energy industry as part of a new round of strategic leading industries to foster economic growth, promoting the construction of new energy projects, from the “solar city” stride “solar city”. In 2014, the Golmud as national model city for first creating a new energy, new energy and urban energy consumption accounted for more than 12%.
2014-2030, Golmud city planning export, Golmud in East, South West, small cooking fires and wutumeiren areas of 5 photovoltaic industrial park, with a total land area of 289.4 square kilometers, 8476 MW of installed capacity, are second to none in the country and even the world.
“Solar city” for desertification
Golmud is a “solar city”, is one of the serious desertification area. Qinghai province, according to the 2009 World War IV monitoring of desertification and sandification of land shows that Golmud City area of 2.319 million hectares of desertified land, of which 334,000 hectares of desertified land, accounting for 14.4%; severe space 1.324 million hectares of desertified land, accounting for 57.1%.
Solar industrial park is located in the Gobi desert region of Qaidam Basin, the ecological environment is very fragile. Special geographical and climatic conditions, determines the vegetation here is extremely scarce, and ecological environment is extremely fragile and very easily lead to dust.
Golmud lack of vegetation, and walk on the streets in the city of Golmud, reporters are dry skin, accompanied by women journalists need to keep your skin hydrated.
According to Li Jianjun memories in 2011, when they first came to Golmud plant, surrounded by the Gobi desert, almost barren. Construction sites are often whipped up tornadoes and sand storms, conditions are very harsh.
According to the staff of the Forestry Bureau of haixi Mongol and Tibetan Autonomous Prefecture, in 2014, invest 153 million Yuan, Qinghai province, afforestation and desertification control project in the PV industry in geermu area, afforestation project covering an area of nearly 25,000 acres, including Nontimber forest crops in lycium barbarum 20,000 acres, effectively promoting the development of PV industry in geermu desertification area ecological environment.
Solar PV development combined with desertification, desertification control, solar photovoltaic power generation project, driving desertification, desertification control, exploration and innovation for China’s desertification, desertification control opens up new ways of realization of the solar photovoltaic industry development and desertification, desertification control in “win-win”.
Power-short term difficult to solve
PV industry in China had left in the world, however, as a result of difficult to dissolve, sending out abandoned wind, abandon light power problem has not been effectively addressed, Golmud is also experiencing pain of industrial development.
In the interview, according to head of the photovoltaic plant reflect, is the biggest problem faced by enterprise development network for new energy rationing increased. Due to the restricted grid conditions, massive new energy channels of power no outward.
“The delivery channel is not ideal, the Group actively considering local absorptive through photovoltaic power system engineering construction in Qinghai province, solved over more than 10,000 people without electricity in the local electricity. “Li introduced.
In recent years, the Golmud City economic development momentum, has taken shape in salt chemical industry, petrochemical industry, metallurgy, special circular economy industries such as light industry, new energy group, has a certain power of absorptive capacity. However, relative to the Grand goal of building photovoltaic industry, very limited absorptive capacity of electricity in Western underdeveloped regions.
Golmud city head of the Department of energy said, at present, the Nonferrous metallurgy of magnesium in the Qaidam Basin integration project is still in the construction phase, very limited absorptive capacity within regional, load depends mainly on transportation of electricity consumption.
One is economic development in West China lags, insufficient demand, electric power market is small, while new energy affluence, particularly the explosive growth in recent years, this will inevitably lead to new energy to dissolve contradictions.
It is understood that the Qinghai haixi area grid is relatively weak, send out 750,000 volts high voltage line from Xinjiang to the help provided by zones cannot, some power plants were “abandoned” a high proportion of many power stations have no Internet access. For the smooth incorporation, part of the power plant has begun to build booster stations and joint fund-raising collection stations.
Experts said the break up wind, abandoned the light problem, still basically depends on new energy and TRANS-provincial districts within a wider scope to dissolve.
But the reality is, the State has published a “Twelve-Five” wind power, solar power and other special planning, power system planning has yet to put forward new energy base out of the channel were not implemented. Taking into account the construction of wind farms, photovoltaic power plant short cycle, and the transmission channel the long construction period, so, in order to guarantee completion of new energy power plants that can be delivered, transmission in connection with the project must be approved in advance, to start.
In addition, solar photovoltaic power is intermittent, random, Schedulability of the low, mass access will have a greater impact on the grid, which is one reason restricted PV normal delivery.
Haixi of Qinghai electric power company branch official said that in recent years, as the country’s power grid construction and constantly improve and transportation improved, but still lagged behind the construction of photovoltaic power stations. At present, the Golmud PV power transmission problems are hard to solve in the short term.
