Networked Energy Storage in New Power Systems

Under the new power system, centralized clean energy bases are a global trend, with examples in China's Sanbei region and overseas projects like Morocco-UK and Indonesia-Singapore. However, rapid clean energy development poses challenges to grid stability, as seen in blackouts in Australia, China, and the UK. Networked energy storage technology, including intelligent string systems and Grid Forming, addresses these issues by providing virtual inertia, reactive power support, and fast frequency response. Solutions like software algorithms and hardware architecture enable millisecond-level response, transient overvoltage control, and low-frequency oscillation suppression. Collaborations with institutions like Tsinghua University and China Electric Power Research Institute have advanced Grid Forming technology, achieving high light-to-storage ratios (up to 200%) and reducing electricity costs by over 30%. Off-grid fault ride-through and minute-level black start capabilities ensure stable operation and prevent load loss. The technology has been demonstrated in GW-level projects, such as the Saudi Red Sea New City, setting a global benchmark for stable, clean power supply.
