Longyuan Power, a subsidiary of CHN Energy, has successfully obtained CNAS (China National Accreditation Service for Conformity Assessment) accreditation for 99 parameters across various fields including wind power, photovoltaic (PV), and storage. This accreditation covers multiple areas such as new energy performance testing, grid connection testing, and simulation modeling. This makes Longyuan Power the first domestic power company authorized by CNAS in these areas.
As the installed capacity of renewable energy such as wind power, PV, and energy storage continues to increase, the concentration of large-scale power electronic equipment connected to the grid poses significant challenges to the stability of the voltage and frequency of the power system. Focusing on optimizing renewable power generation and enhancing grid support, Longyuan Power established a renewable energy testing laboratory dedicated to providing renewable energy technology services.
The most recent CNAS accreditation application includes 99 parameters such as PV performance testing, new energy grid adaptability and fault ride-through capability testing, new energy transient simulation modeling, power plant frequency and voltage regulation, and power quality throughout the entire process of power generation, transmission, and transformation from single-unit power generation performance to power plant voltage and frequency support levels and regional power system stability analysis. To date, the laboratory has completed testing and simulation modeling for 18 power plants across seven provinces.
The CNAS accreditation signifies that CHN Energy has achieved industry-leading levels in performance testing, grid connection testing, and simulation modeling in the new energy field. This provides strong technical support for the safe, stable, and efficient integration of new energy power plants into the grid.
