Innovation drives development: GreenMore wins the "Photovoltaic Science and Technology Award"

Recently, the list of winners of the highly anticipated "Photovoltaic Science and Technology Award" was officially announced by the Photovoltaic Industry Association. GreenMore stood out with its "Research and Industrialization of Grid-Type Energy Storage Bidirectional Converters" project and was honored to be on the list. This honor not only demonstrates GreenMore's outstanding strength in the field of energy storage technology, but also highly recognizes and praises its continuous innovative spirit.

The project successfully developed and industrialized a grid-type energy storage bidirectional converter. This technological breakthrough has undoubtedly injected new vitality into the intelligent and efficient operation of photovoltaic energy storage systems. As the core equipment in the energy storage system, the grid-type energy storage bidirectional converter can realize the bidirectional flow and efficient conversion of electric energy, providing a solid guarantee for the stable operation of photovoltaic power stations and the flexible dispatching of power grids.

Technological innovation highlights

• Power synchronization strategy: The grid-type energy storage bidirectional converter adopts a power synchronization strategy similar to that of the synchronous generator, which can achieve synchronization without the aid of a phase-locked loop, greatly improving the stability and response speed of the system.
• Grid regulation and control: Through the voltage-reactive power droop curve and frequency-active power droop curve, this technology can achieve precise regulation and control of grid voltage and frequency to ensure stable operation of the grid.
• Virtual inertia and damping: Grid-connected converters can provide virtual inertia and damping for the power system with the help of energy storage devices, effectively suppressing the rapid drop and oscillation of the grid frequency and enhancing the stability of the power system.
• Fast power regulation response: This technology has fast power regulation response capability, which can realize fast regulation of active and reactive power, as well as virtual inertia support, active primary frequency regulation, voltage regulation and other functions, and supports secondary frequency regulation.
• Seamless switching and parallel characteristics: The grid-connected energy storage bidirectional converter also has the characteristics of seamless switching between on-grid and off-grid, and multi-machine parallel connection, which can achieve uninterrupted power supply to critical loads and support flexible access and safe and stable control between microgrids and large power grids.

Typical project case: Solar-storage-diesel microgrid system in Chilean mining area

GreenMore's innovative technologies have been successfully applied in actual projects. The 1.3MW/9.1MWh photovoltaic storage and diesel microgrid project in the Chilean mining area is one of them. The project aims to significantly improve the stability and reliability of power supply by optimizing the power supply structure, ensuring that the power demand for production and daily life in the mining area is fully met. At the same time, the system has also significantly improved the utilization rate of the photovoltaic system, effectively reduced the phenomenon of "abandoned light", and thus greatly improved the overall economic benefits. This innovative solution has brought a more reliable, efficient and economical power solution to the mining area.

Significant project benefits

• Improve the stability of power supply: The off-grid microgrid project with solar energy storage and diesel fuel ensures that the mining area can obtain stable power supply under any circumstances to meet the electricity needs of production and life.
• Improve the economic benefits of photovoltaic power generation systems: By increasing the utilization rate of photovoltaic power generation systems and reducing the phenomenon of abandoned light, the photovoltaic storage and diesel off-grid microgrid project has significantly improved the economic benefits of photovoltaic power generation systems.
• Reduced energy consumption and carbon emissions: The project uses renewable energy (such as solar energy) to generate electricity, reducing dependence on traditional fossil energy, thereby reducing energy consumption and carbon emissions.
• Enhance the self-sufficiency of the mining area: By configuring the off-grid microgrid project of solar energy storage and diesel, the mining area has a stronger self-sufficiency, reduces dependence on external power supply, and improves energy security and stability.

In the future, GreenMore will continue to unswervingly strengthen product research and development and innovation, and strive to improve the technical content and added value of products, so as to accurately meet the urgent needs of domestic and foreign customers for efficient, reliable and intelligent energy storage products. On this basis, the company will actively expand domestic and foreign markets, actively seek in-depth cooperation with domestic and foreign partners, jointly explore the international market, further increase the market share of products and expand brand influence.
