China Southern Power Grid: Meet the 22GW distributed photovoltaic grid-connected demand during the "14th Five-Year Plan" period

　　Recently, "China Southern Power Grid's "14th Five-Year Plan" Rural Power Grid Consolidation and Improvement Plan" (hereinafter referred to as the "Plan") was officially released
.
According to the "Plan", China Southern Power Grid Corporation plans to invest 187 billion yuan to basically build a safe, reliable, green, efficient and intelligent modern rural power grid by 2025.
Rural revitalization and new urbanization construction provide energy support
.

　　The "Planning" requires that by 2025, the company's customers in rural areas will have an average annual power outage of less than 8 hours, the first-end voltage qualification rate of the distribution station area will reach 100%, the voltage qualification rate will not be lower than 99%, and the average distribution transformer capacity of rural households will not be less than 100%.
Less than 2.
5 kVA, the equalization index of urban and rural power supply services is less than 4.
2, the reliability rate of power supply by county is not less than 99.
8%, the voltage qualification rate is not less than 97.
9%, and the per-household distribution transformer capacity is not less than 2 kVA
.
The equalization of urban and rural power supply services is basically achieved, and the load growth and safe and reliable power supply requirements in rural areas are fully met.
The power supply quality and service level are continuously improved, and the level of digital automation and intelligence has been significantly improved.
The rural power grid is observable, measurable and controllable, and rural distributed new energy The proportion of electric energy in rural energy consumption continues to increase
.

　　Focusing on the implementation path, the "Plan" clarifies the key contents in five aspects: consolidate the achievements of a new round of rural power grid transformation and upgrading, and improve the level of power security in key areas; accurately upgrade rural power grids to help upgrade and upgrade rural modern infrastructure; improve rural electrification It serves the modernization of agriculture and rural areas and the upgrading and development of rural industries; enhances the consumption capacity of distributed new energy in rural areas and promotes the construction of a modern energy system in rural areas; improves the level of rural power supply services and realizes the equal development of urban and rural power supply services
.
At present, the "dual carbon" goal promotes the deep integration of green energy development and rural revitalization, and accelerates the formation of a green and diverse rural energy system
.

　　According to forecasts, during the "14th Five-Year Plan" period, the company's rural power grid is expected to add 65 million kilowatts of power installed capacity of 110 kV and below
.
Among them, the newly added installed capacity of wind power is 14 million kilowatts, including 210 thousand kilowatts of distributed wind power; the new installed capacity of photovoltaic energy is 43 million kilowatts, including 22 million kilowatts of distributed photovoltaic installed capacity
.
"The company will combine the action of harnessing wind in thousands of villages and villages and the action of cultivating light for thousands of households to promote the scientific planning and orderly development of new energy in rural areas, strengthen the effective connection between new energy projects and rural power grids, and achieve a renewable energy consumption rate of 95%.
, so that the new energy in rural areas should be 'combined' and fully absorbed
.
" The relevant person in charge of the company's planning department introduced
.
Taking distributed photovoltaics as an example, the company will focus on promoting the pilot work of distributed rooftop photovoltaics in 83 rural counties and districts announced in the southern region, do a good job in the calculation of the carrying capacity of regional power grids, and promote the construction of supporting power grid projects.
During the "14th Five-Year Plan" period, Meet the grid-connected demand for 22 million kilowatts of distributed photovoltaics
.

　　With the continuous improvement of the income level and quality of life of rural residents, by 2025, the electricity consumption of the whole society in the rural areas of the five southern provinces will exceed 750 billion kWh, and the maximum load of the whole society will be about 130 million kWh
.
In order to further consolidate and upgrade the rural power grid, during the "14th Five-Year Plan" period, the company plans to build and expand 1,140 substations of 110 kV and below, and increase the substation capacity of 110 kV and below by 74 million kVA; 10,000 units, new distribution transformer capacity of 29 million kVA, and 380,000 kilometers of new and reconstructed lines
.
