[Source: "New Industry" February issue / Hu Yanling] Since 2012, Zhang Guangchun has been working on the grid connection of self-built photovoltaic power plants for his own roof, which is more realistic with the national grid.
At the beginning of November 2012, Zhang Guangchun once again came to the National Grid Wuxi Dongting Customer Service Center to submit an application for self-built photovoltaic power station network access. Prior to this, Wuxi Dongting Customer Service Center always believed that Zhang Guangchun's self-built photovoltaic power station was illegal and certainly could not enter the network.
In late September 2012, the National Energy Administration issued the Notice on Declaring the Application Zone for Large-Scale Application of Distributed Photovoltaic Power Generation (hereinafter referred to as “Noticeâ€). In late October, State Grid issued the “Provisional Opinion on Doing a Good Job of Distributed Generation Grid-Connected Services†(hereinafter referred to as “Opinionsâ€). With these two documents, Zhang Guangchun, Chairman of SEMI China Photovoltaic Standards Technical Committee I thought that the grid connection of photovoltaic power plants on the roof should not have much problem.
but it is not the truth.
Although the application submitted by Zhang Guangchun was accepted, the staff was not familiar with how the policy was implemented. Subsequently, Zhang Guangchun was asked to provide the approval document for the construction of the photovoltaic power station by the Wuxi Development and Reform Commission. The photovoltaic power station construction project has been approved by the local development and reform commission, and it also needs multi-sector review and approval of environmental assessment, energy assessment, planning, and land. The links are cumbersome and complicated.
"Now the leaders of the competent departments also believe that to simplify the approval procedures for PV power grid integration, the administrative approval level should be separated according to the size of the PV power plant," Zhang Guangchun said.
In fact, Zhang Guangchun's experience is only the tip of the iceberg of the problem of grid-connected photovoltaic power generation.
“Spontaneous use, the use of nearby areas should be the most effective way of distributed photovoltaic power generation in China.†Zhang Guangchun said to “New Industry†that self-use and self-use can also allow more individuals and small investment institutions to enter the field of photovoltaic power generation, which is conducive to the scale of photovoltaic power generation. Application.
Stimulating domestic demand
Distributed photovoltaic power generation refers to a modular, decentralized, highly efficient and reliable photovoltaic power generation unit located near the user.
At present, China's photovoltaic power generation is mainly based on the construction of large-scale ground power stations and solar roof projects, but both projects face difficulties in grid-connected operation and management.
The two documents issued by the National Energy Administration and the State Grid are undoubtedly a “cardiotonic agent†for the Chinese PV industry, which has a serious overcapacity, and can effectively utilize distributed photovoltaic power generation to digest excess capacity.
Zhang Guangchun told the "New Industry" that as of the end of 2010, the cumulative installed capacity of global distributed photovoltaic systems was about 23. 4 GW, accounting for 66.8% of the cumulative installed capacity of photovoltaic power generation. Among them, the German distributed generation system has the highest installed capacity, reaching 14.9GW; while the installed capacity of China's distributed generation system is only 0.26MW, and the growth space is huge.
According to the Notice, in the first phase of the project for the application of distributed power generation large-scale application demonstration, the number of declarations supported by each province shall not exceed three, and the declared total installed capacity shall not exceed 500 M W in principle. If the calculation is not more than 500M W in each province, the upper limit of the total installed capacity of the national distributed photovoltaic power generation large-scale application demonstration zone is 15GW.
In 2012, the domestic Golden Sun Project has a total installed capacity of 1.7GW, and the second batch of Golden Sun demonstration projects is expected to be around 2GW. This also means that by the end of 2013, the total installed capacity of domestic Golden Sun Project is expected to reach 3.7GW.
From this point of view, although China's distributed photovoltaic power generation project is still in its infancy, it is undoubtedly a gift to the Chinese PV industry with severe losses and overcapacity.
Incomplete statistics show that the total inventory of the five largest PV module manufacturers in China, such as Trina Solar, Suntech Power, and Yingli Green Energy, is as high as 5GW, while the total inventory of domestic PV manufacturers is estimated to be more than 20GW. On the contrary, the total global PV installation demand will not exceed 30G watts a year.
