Three ministries and commissions set up a photovoltaic work group and the ITU will come to the forefront

According to CEC's Standardization Management Center, the National Standardization Management Committee jointly established the Photovoltaic Power Generation and Industrialization Standardization Promotion Team with the Ministry of Industry and Information Technology and the National Energy Administration, and issued the "Notice on the Establishment of a Photovoltaic Power Generation and Industrialization Standardization Promotion Group". The Federation is the unit leader of the grid-connected power generation working group and is responsible for the standardization and daily management of photovoltaic grid-connected power generation.

It is understood that in order to promote the development and standardization of the photovoltaic power generation industry, China established the National Technical Committee for the Standardization of Solar Photovoltaic Energy Systems as early as 1987. It has formulated some basic standards, and has subsequently adopted some internationally accepted IEC (International Electrotechnical Commission). Photovoltaic standards are converted to replace some of the original standards.

In 2011, the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China organized a special research project for the scientific research of the public welfare industry entitled “Development of Key Technical Standards for Photovoltaic Grid-Connected Power Generation.” The project is led by the China Electric Power Enterprise Federation, the China Electric Power Research Institute, the State Grid Electric Power Research Institute, and related standard-writing units, and participates in the development of standards and related standards. Through the analysis and study of domestic and foreign photovoltaic grid-connected power generation standard systems, Build a sound and reasonable photovoltaic grid-connected power generation standard system in China.

The project has formulated 14 national standards for photovoltaic grid-connected power generation, including: technical regulations for photovoltaic power station access to power systems; technical regulations for photovoltaic power generation systems to access distribution networks; regulations for photovoltaic power stations connected to power grids; and access to photovoltaic power generation systems Specification for distribution network inspection; Technical specifications for evaluation of grid-connected photovoltaic power generation system characteristics; Technical requirements and test procedures for grid-connected photovoltaic power generation inverters; Technical specifications for start-up acceptance of grid-connected photovoltaic power plants; Technical requirements for lightning protection and grounding of photovoltaic power stations; Photovoltaic power generation Technical requirements for station monitoring systems; Control specifications for grid-connected photovoltaic power stations; Technical specifications for reactive power compensation for photovoltaic power stations; Technical requirements for solar tracking systems for photovoltaic power stations; Modeling guidelines for photovoltaic power generation systems; Technical specifications for real-time monitoring of solar power resources at photovoltaic power stations In addition, 10 photovoltaic grid-connected power generation industry standards have been formulated, including: technical regulations for low voltage ride-through detection of photovoltaic power stations; technical regulations for power quality inspection of photovoltaic power stations; technical regulations for power control capability testing of photovoltaic power stations; Transmitter power quality inspection technical regulations; Technical specifications for voltage and frequency response detection of power station inverters; Technical regulations for the detection of anti-islanding effects of photovoltaic power station inverters; Test and evaluation methods for grid-connected photovoltaic power stations; Technical requirements for photovoltaic power station power prediction; Technical specifications for photovoltaic power station post-evaluation Photovoltaic power station environmental impact assessment technical specifications.

In recent years, although China has become a major producer of photovoltaic industry in the world, the standard specifications of China's photovoltaic industry are seriously missing, which in turn affects the international competitiveness of China's photovoltaic products. With the rise of photovoltaic power generation in the domestic market, China's photovoltaic grid-connected power generation standards will gradually improve. The establishment and promotion of standards and regulations can not only effectively prevent industry chaos, increase the overall level of photovoltaic power generation, but also ensure the safety of power grid operation.
