On June 25th, the National Joint Office held a series of theme press conferences on promoting high-quality development. Du Zhongming, director of the Power Department of the National Energy Administration, said that in order to meet the requirements of large-scale development of distributed new energy, the construction and renovation of distribution networks will be strengthened to create a strong and flexible grid framework, improve intelligence. Level, improve scheduling and operation mechanism. By 2025, the distribution network will have a capacity of about 500 million kilowatts to access distributed new energy.

Previously, the National Development and Reform Commission's website mentioned that by 2025, the grid structure of the distribution network will be more strong and clear, and the power supply and distribution capacity will be reasonable and sufficient. The bearing capacity and flexibility of the distribution network will be significantly improved, and there will be around 500 million kilowatts of distributed new energy and about 12 million charging piles connected to the distribution network.

Taking distributed photovoltaics as an example, according to data from the Energy Research Institute of the National Development and Reform Commission, China's newly installed distributed photovoltaics will reach 96.29 GW in 2023; the cumulative installed distributed photovoltaics will be 253 GW.

"At present, the main form of distributed new energy is distributed photovoltaics. Judging from the current access data, 500 million kilowatts is equivalent to doubling the current amount, and this access volume is still relatively large." Peng Peng, secretary-general of the China New Energy Power Investment and Financing Alliance, told the Science and Technology Innovation Board Daily reporter.

Several companies respond: sufficient orders.

"In the process of distributed new energy access to the distribution network, the usage of basic infrastructure will also increase significantly." Peng Peng further told the Science and Technology Innovation Board Daily reporter.

It is reported that the transmission and distribution equipment required for distributed new energy access to the distribution network includes transformers, switchgear, cables, reactive power compensation devices, filters and other equipment, as well as intelligent monitoring and communication equipment. Among them, transformers are critical equipment in transmission and distribution systems, which are used to change the voltage level and achieve long-distance efficient transmission of electrical energy.

"The orders for transmission and distribution and control equipment have been saturated, with an expected increase of 20-30% this year." Hope Electric Securities Division personnel told the reporter of Science and Technology Innovation Board Daily that the increase in transmission and distribution equipment-related orders is mainly driven by policies. One of Hope Electric's main businesses is the manufacturing of transmission and distribution and control equipment, including power transformers, box-type substations, complete sets of electrical equipment, etc.

"The orders for distribution network have always been sufficient." Jingguan Electric also told the Science and Technology Innovation Board Daily reporter. "In terms of transmission and distribution equipment, the amount of the company's surge arresters, switchgear, ring network cabinets, first- and second-level fusion equipment is relatively large."

Sojo Electric personnel told the Science and Technology Innovation Board Daily that "this year the company has sufficient orders in hand". Currently, the company is actively expanding its industrial-side customers on the basis of major customers such as Southern Grid, so as to improve the quality of its orders." Sojo Electric's main businesses include the manufacturing of distribution and control equipment, intelligent grid and other businesses.

Siyuan Electric told the Science and Technology Innovation Board Daily reporter that specific order data is not convenient to disclose. However, the company revealed in the research summary that transformer orders meet the company's order growth target and delivery is normal, and the current production capacity planning can meet the demand for orders.

What is the impact on the photovoltaic industry?

"Overall, policies will have a strong driving force on the photovoltaic industry." Peng Peng, secretary-general of the China New Energy Power Investment and Financing Alliance, told the Science and Technology Innovation Board Daily reporter, the status of the distribution network is constantly increasing, and the new energy industry is gradually evolving towards a balance between centralized and distributed.

Taking distributed photovoltaics as an example, the penetration rate of distributed photovoltaics has gradually increased in recent years. According to calculations by the State Grid Corporation, the maximum installed capacity of distributed photovoltaics is expected to exceed 800 million kilowatts.

However, as the installed capacity of distributed photovoltaics increases, the problem of grid bearing and absorption gradually emerges. In some areas, due to the limited capacity of the grid, distributed photovoltaic projects may face challenges such as difficulty in grid access and restricted power generation.

Deng Wei, an analyst at Huafu Securities, said that on the one hand, the grid bearing capacity is insufficient, and the capacity of power supply and distribution on the distribution side is limited. With the large-scale access of household photovoltaics, transformer overload problems have occurred in many regions. On the other hand, household photovoltaics are basically operated in full grid-connected mode, resulting in some regions experiencing anti-power transmission during certain periods, reducing economic efficiency.

At present, in order to solve the problem of distributed photovoltaic absorption, various places are exploring various solutions, such as centralized convergence into the grid, wall-to-wall electricity sales, and micro-grids.

According to Deng Wei, an analyst at Shanxi Guoxin Energy Corporation in China, the resolution of new energy grid connection and absorption issues is a gradual process that involves policy guidance first, followed by industry self-adjustment and adaptation, ultimately leading to the relatively balanced economic efficiency of power sources and power grids. With the acceleration of distribution network reform and construction, the scaling up of distributed access, the enhancement of residual new energy power export and absorption capacity, and the promotion of the construction process of distributed centralized convergence and grid connection, a solution can be achieved.

Meanwhile, distributed photovoltaics have already laid a foundation for market entry. According to the calculation by analysts at Shanxi Guoxin Energy Corporation, the comprehensive electricity price for commercial and industrial photovoltaics in Shandong after entering the market is 0.41 yuan/kWh, and the IRR is still 18%. Deng Wei and others believe that the profitability of photovoltaic operators will increase significantly with system improvements in the future.

Looking at the overall trend, Peng Peng, the Secretary General of the China New Energy Power Investment and Financing Alliance, said that as the price of photovoltaic modules decreases, the amount of distributed photovoltaic access to the distribution network will increase. Therefore, the overall trend for the future is positive.

At the same time, it is believed that multiple parties will participate in the future. Peng Peng told reporters from the Star Daily that "a large amount of fluctuating power sources need to make the distribution network more elastic, and this requires the involvement of flexible power consumers such as energy storage, virtual power plants, and charging stations."
