Sungrow Shares 10 Major Technological Trends in Renewable Energy Industry

SHANGHAI, June 14, 2024 /PRNewswire/ -- Sungrow, the global leading PV inverter and energy storage system provider, shared 10 major technological trends at the recent Ph.D Talk event in Shanghai. With an investment of 2.45 billion yuan (approximately 347 million) in R&D throughout 2023, the company stands at the forefront of technological innovation. Embracing their brand-new tagline "Bridge to a Sustainable Future", Sungrow is dedicated to bridging the gap and making clean energy accessible to everyone.

Ph.D. Xu Jun, Vice President of Sungrow Research Center, highlighted 10 Major Technological Trends at Ph.D. Talk:

    1. The Application of New Semiconductor Devices To achieve net-zero carbon
       emissions, advancements in energy generation, transmission, and
       conversion efficiency are crucial. According to Diamfab, diamond has the
       potential to become the ultimate WBG semiconductor material for
       high-power electronics. Diamond possesses ideal characteristics for
       high-voltage operation, high-temperature applications, and high-frequency
       switching, with a critical electric field 30 times higher than Si and 3
       times higher than SiC.



    2. The Extended Utilization of Solid-State Transformer (SST) Technology and
       Medium-Voltage Photovoltaic (PV) Inverters The medium-voltage PV power
       generation system based on SST technology offers a higher power density
       compared to traditional solutions, with an overall improvement in
       conversion efficiency. In the future, SST technology may find
       applications in MW-level charging stations, HVDC power supply systems for
       data centers, energy routers, and more. Notably, Sungrow developed the
       world's first 35kV SST-based PV inverter in 2022.



    3. Further Enhancement of Direct Current (DC) Voltage Level in PV Systems
       The increase of DC voltage in PV systems not only increases power density
       and efficiency but also reduces infrastructure and maintenance costs.
       Notably, Sungrow achieved a groundbreaking milestone by becoming the
       world's first company to introduce the 2000V solar-plus-storage
       high-voltage system and successfully integrating it into the grid in
       Yulin, Shaanxi.



    4. Improving the Overall Lifecycle Efficiency of PV Power Plants through
       Digitization and AI Sungrow has introduced the concept of DEPCO
       (Development, Engineering, Procurement, Construction, Operation),
       bringing about comprehensive digitization to renewable energy power
       plants. The company has developed cutting-edge software solutions, namely
       iSolarTool for optimizing the design of large-scale PV power plants, and
       iSolarBP for commercial and industrial PV assessment and design. By
       leveraging AI intelligence, these innovative tools enable end-to-end
       system optimization, effectively boosting the efficiency and
       profitability of renewable energy development. Currently, these solutions
       are in the industry trial phase.



    5. "PE Agent," a Power Electronic Designer Based on Large Language Model
       (LLM) During the energy transition, AI intelligence will play an
       increasingly significant role. PE Agent  can facilitate seamless
       communication between AI and AI, as well as between AI and humans,
       enabling intelligent management of the entire process of power
       electronics design and achieving "self-learning" and "self-evolution."



    6. High Voltage Direct Current (HVDC) Technology HVDC systems provide faster
       active power flow control compared to the more established CSC-HVDC
       technology. Additionally, they offer flexible and enhanced reactive power
       controllability at both converter terminals.



    7. Source-Grid-Load-Storage Integration: Driving the Rapid Development of
       Energy Bases and Future Urban Construction The construction strategy for
       the source-grid-load-storage operation mode in renewable energy
       integration can leverage multiple energy sources, enhance grid capacity
       for renewable energy integration and economic efficiency of active
       distribution grid operations.



    8. Grid-Forming (GFM) Technology GFM technology provide rapid, accurate, and
       standardized dynamic responses to grid faults and disturbances. It offers
       strong support for the stable operation of new power systems in various
       application scenarios.



    9. Virtual Power Plants (VVPs) VVPs are networks comprising small-scale
       energy-producing or storage devices, such as solar panels and batteries,
       that are aggregated to serve the electricity grid. With the consent of
       their owners, the energy generated by these devices can be accessed by
       utilities during periods of high demand or saved for future use.

    10. Green Hydrogen The off-grid solar-hydrogen solution, IGBT-based hydrogen
        production rectifier power supply, and the integration of hydrogen for
        complete energy self-sufficiency in residential buildings with PV and
        battery storage systems can further enhance energy efficiency.
