Let the "sunshine" spill into the pockets of the masses

2019 is the key to winning the battle against poverty. As the backbone of this battle, photovoltaic poverty alleviation has achieved phased results, and the quality problems of its photovoltaic power plants cannot be avoided.
From the source of the Three Rivers to the Hehuang Valley, from the Qilian Mountain Grassland to the Kunlun Mountain Gobi, in the province of China's light resource endowment - Qinghai, photovoltaic poverty alleviation is spreading the "sunshine" to the pockets of the masses, bringing hopes to more poor households. .
On March 27th, Qinghai Province's “13th Five-Year Plan” largest-scale village-level photovoltaic poverty alleviation project – the 29.1MW village-level poverty alleviation photovoltaic power station in Guoluo broke ground. The power station consists of 8 village-level photovoltaic units, with total installed capacity. 29.1 million kilowatts, the program was completed and put into operation in June this year. After completion, it is estimated that the annual average power generation will be 40 million kWh.
Not only in Qinghai, photovoltaic poverty alleviation has blossomed more and more across the country. As of August 31 last year, the National Power Bureau has issued a total of 15.44 million kilowatts of photovoltaic poverty alleviation plans, and the country's 26 provinces have built 13.53 million kilowatts of grid-connected photovoltaic poverty alleviation projects, with a total of 2.24 million.
2019 is the key to winning the battle against poverty. As the backbone of this battle, photovoltaic poverty alleviation has achieved phased results, and the quality problems of its photovoltaic power plants cannot be avoided. The danger of winning the bid at the lowest price and selecting low-priced and defective products has become an unacceptable burden for PV poverty alleviation.
The grid is in a difficult situation
Photovoltaic poverty alleviation is a combination of photovoltaic promotion and application, industrial poverty alleviation and precision poverty alleviation. It completes the transformation of “transfusion-type poverty alleviation” to “hematopoietic poverty alleviation”. The specific content is that the government helps rural poor households and poor villages to use housing roofs. Or build a photovoltaic power station in idle wasteland, “spontaneous use, surplus Internet access”, and obtain stable income by selling electricity to the national grid.
However, according to the reporter's understanding, in Shanxi, Anhui, Guangxi and other places, with the increase of photovoltaic poverty alleviation projects, the planning continues to increase, the grid's ability to absorb the power generation of photovoltaic poverty alleviation power plants is limited, leading to the emergence of light problems everywhere.
Taking Shanxi as an example, the maximum capacity of the power grid to the village-level poverty alleviation power station is 1 million kilowatts. Beyond the above plan, the power grid will be abandoned due to difficulty in consumption. At present, the installed capacity of photovoltaic poverty alleviation projects with grid-connected power generation in Shanxi has reached 786,600 kilowatts. In addition, many photovoltaic power plants are under construction. It is estimated that the installed capacity of local photovoltaic poverty alleviation power stations will soon break the upper limit of consumption.
“The spurt development of poverty alleviation photovoltaics will create a huge burden on the power grid in poverty-stricken areas.” Miao Shihong, a professor at the School of Electrical and Electronic Engineering at Huazhong University of Science and Technology, pointed out that photovoltaic poverty alleviation projects are basically built in poverty-stricken areas, and the grid structure of power grids is weak. There is even a phenomenon of “one town, one change, one village and one line”.
Considering that the distribution network in the poverty alleviation area is relatively weak, the load capacity is insufficient, and the dynamic matching with the PV output is not formed, Miao Shihong shows that the disorderly access of many poverty alleviation photovoltaics leads to voltage overrun, network loss and absorption. The difficulty and other issues have affected the operational efficiency and overall benefits of the power grid in poverty alleviation areas. Therefore, how to ensure the friendly access of poverty alleviation photovoltaics has become a problem that the distribution network in poor areas does not need to deal with.
In addition, according to the current project review guidelines, the project establishment process of the PV project is relatively convenient, and the project of the supporting power grid project is messy and has a long cycle. In addition, after the power project is established, the network connection is requested, and the supporting project is formed objectively. Lagging behind the power supply project, there is a time difference, this actual situation will also constrain the timely compensation of the grid's capacity to absorb, leading to difficulties in grid access review.
The quality of the power station is about victory or defeat.
In addition to grid consumption, the quality of photovoltaic power station construction is also a topic of great importance in the industry. The quality of photovoltaic poverty alleviation power stations is not good, and the “money bag” of the public is difficult to swell.
Not long ago, at a symposium on “Building quality and effectiveness to create a new era of photovoltaic poverty alleviation”, Ji Zhenshuang, deputy director of Beijing Certification and Certification Center, analyzed the existence of power stations with low efficiency and insufficient power protection. problem. For example, the low performance of power stations is mainly due to improper selection of sites, unreasonable array design, poor performance and quality of equipment, and inability to keep up with operation and maintenance.
The above results are also the Beijing Certification and Certification Center in 10 provinces and 45 counties across the country. It has carried out various forms of power station testing and evaluation for nearly 400 village-level and village-level joint power stations and 40 centralized poverty alleviation power stations that have been put into operation. The conclusion drawn from the work.
