Since China’s “Renewable Energy Law†was enacted in 2005, under the support of industrial policies such as the “Bright Plan†and “Golden Sun Planâ€, especially under the strong demand of the international market, China’s solar photovoltaic industry has been able to make rapid progress. Develops and has become a major producer of photovoltaic products worldwide.
However, it is undeniable that the photovoltaic industry, which mainly depends on the strong demand in the international market, is increasingly dependent on its external demand. At the same time, many “uncertain†factors in the international market are also constraining its future development. Increase accordingly. Therefore, in order to ensure the sustainable and healthy development of China's solar photovoltaic industry, it is imperative to change the embarrassing situation of China's current solar photovoltaic power generation market with "great potential and minimal application." That is, we must cultivate relatively stable and rapid growth. The domestic demand market, and the key to nurturing the domestic demand market is to break through the bottleneck of industrial application.
Photovoltaic power generation industrialization bottleneck
From the perspective of the type of application, solar photovoltaic power generation applications can be divided into three types: First, the solar photovoltaic power station for power generation after the acquisition by the State Grid and the grid; Second, the solar photovoltaic power station after power generation completely for personal use and digestion; third is solar energy After the PV power station generates electricity, it is combined with the grid transmission at the user end.
From the perspective of application conditions, if the State Grid Corporation of China is responsible for the grid-connected acquisition of solar photovoltaic power plants, then in order to avoid shocks or pollution on the national grid, it will inevitably involve more complicated grid-connected procedures and pricing procedures. High technical thresholds; If the solar photovoltaic power plant is fully used and digested after it is generated, it is necessary to build an energy storage device that is compatible with the photovoltaic power plant. The construction of the energy storage device is not only of large investment, but also requires high security and safety. It is difficult to meet the requirements of industrial development.
Due to the bottleneck reasons mentioned above, in recent years, "photovoltaic microgrid technology" has been widely paid attention to after the "photovoltaic photovoltaic power station is used for power generation at the user's end and the power grid is used for power generation." The main reasons for the photovoltaic power microgrid technology are immediate use, Without the advantages of energy storage, strong applicability, and obvious benefits, it has been widely accepted as a mode of development and utilization of a new type of clean energy that is more suitable for actual operation in the current circumstances.
Photovoltaic microgrid system integration features
In principle, the photovoltaic micro-grid technology is the combined use of photovoltaic power generation and grid transmission at the user's end to achieve the effect of "two networks complementing each other." For example, when there is plenty of sunshine and the photovoltaic power generation efficiency of a solar photovoltaic power station is high, photovoltaic power is used as much as possible. At this time, the power transmission of the grid is only used as an auxiliary supplement. When the sunshine is weak, power transmission using the power grid is dominant.
From the perspective of technology, the key to the industrial application of photovoltaic micro-grid technology lies in the maturity of system integration, because it is related to how to effectively integrate existing mature technologies and achieve optimal configuration. It also involves systems. Integration of the relevant core technology breakthroughs, so the degree of system integration in the technology, will directly affect the industrial application of photovoltaic micro-grid technology.
In addition, since there is no energy storage device in the system integration of photovoltaic micro-grid technology, the target customer group for industrial application is relatively clear, mainly industrial parks and large-scale shopping malls, because industrial parks and large-scale shopping malls are During the day, basically all major power users.
In addition, the factory buildings and large shopping malls in the industrial park all have large-area roofs suitable for installing solar modules. With the rapid development of thin-film batteries, solar cell modules can be installed on arched or shaped roofs, and even solar panels can be installed on some walls or windows.
Industrial application bottlenecks have been broken
After years of unremitting efforts, and through the verification of the operational practice of the demonstration project of photovoltaic micro-grid model established in Shanghai Qishi Science and Technology Park, Shanghai Qiyate Energy Co., Ltd. (hereinafter referred to as “Chiyatâ€) ) Has broken through the bottleneck of industrial application of photovoltaic micro-grid system integration.
It is understood that "Qiyat" is in Shanghai Industrial Development Consulting Co., Ltd., Shanghai Green Industry Promotion Association, Shanghai Urban Industrial Association, Shanghai Financial Leasing Industry Association, and Chinese Academy of Sciences Institute of Electrical Engineering (Beijing Connaught Weiye Technology Co., Ltd. Under the strong support of the Shanghai Branch of the Chinese Academy of Sciences, the Shanghai National Technology Transfer Center of the Chinese Academy of Sciences, the Shanghai Solar Cell Research and Development Center, and the Shanghai Pudong Economic Development Corporation, Minjiang District, Shanghai, Shanghai Qishi Enterprise Development Co., Ltd. is the main investment entity and unites the society. The joint-stock companies established by other investors to promote the industrialization of new energy.
Shanghai Qishi Enterprise Development Co., Ltd., which is the main investment entity of Qiate, has been dedicated to the development of high-tech industries in recent years. At the same time, the company is also the president of the Shanghai Metropolitan Industrial Association. Many of the members of the association own industrial parks, business parks, and creative parks of a certain scale.
In addition, Beijing Kono Technology Co., Ltd., which is a strategic partner and core technology provider of “Qiyatâ€, is a high-tech company established in 2001 on the basis of scientific research accumulated by the Institute of Electrical Engineering of the Chinese Academy of Sciences for more than 30 years. The main business is the design and integration of photovoltaic products and photovoltaic systems.
At present, "Chiyat" is building a new energy industrial base with the characteristics of "new energy application system integration port" in Pujiang Town, Minhang District, Shanghai. It is understood that the first phase of the project covers an area of ​​67,000 square meters and will build 80,000 square meters of standard factory buildings, business displays, R&D centers and other buildings.
