Core Viewpoint - The article emphasizes the importance of grid-forming technology in stabilizing the power grid as renewable energy sources become more prevalent, highlighting the innovative approaches of companies like Sungrow Power Supply Co., Ltd. in this field [3][4][10]. Group 1: Grid-Forming Technology - The transition from Grid Following to Grid Forming is crucial for integrating renewable energy into the power grid, as traditional synchronous generators are unable to support grid stability when renewable sources dominate [3][4]. - Grid-forming energy storage systems act as voltage source systems, providing inertia response and frequency support to maintain grid stability amidst increasing renewable penetration [5][6]. Group 2: Sungrow's Innovations - Sungrow has developed advanced grid-forming capabilities, leveraging 20 years of experience to lead the trend of "adapting to the grid" and has implemented GW-level black start technology in projects like the 7.8 GWh energy storage station in Saudi Arabia [6][9]. - The company has introduced revolutionary AC storage technology, which integrates battery cabinets and power conversion systems, achieving up to 30% space savings and enhancing safety and efficiency [8][9]. Group 3: Industry Landscape - The energy storage industry is experiencing rapid growth, with over 260,000 domestic companies entering the market, leading to intensified competition in pricing, costs, technology, and services [9][10]. - Despite the competitive landscape, Sungrow remains confident in its technological advancements and product quality, supported by a robust team of nearly 7,000 R&D personnel and over 520 service outlets globally [9][10]. Group 4: Long-term Commitment - Sungrow's commitment to long-term investment and innovation is seen as essential for navigating the challenges of the energy transition and contributing to global clean energy solutions [10][12].
