[The world's first 500 kV economical high voltage AC current limiter] A few days ago, the world's first 500kV/90kA economical high-voltage AC current limiter developed by China Xidian Group successfully completed the manual short-circuit test and was successfully put into operation on the Shun-Guang-A line of the 500kV Guangnan Station. The successful operation of the project has filled the domestic economical AC ultra-large short-circuit current suppression technology gap, provided an economical and reliable solution for the suppression of high-voltage AC short-circuit current, and provided a strong guarantee for the reliable operation of the ultra-high-voltage large power grid.

• [Australia: 120 gigawatt hours of energy storage can provide 98.5% renewable energy supply]
• The latest simulation study shows that the Australian national electricity market can achieve nearly 100% renewable energy supply with only 24 gigawatts/120 gigawatt hours of energy storage, of which renewable energy accounts for 98.5% and the remaining 1.5% is supplemented by other energy sources. This simulation is based on actual electricity data since August 2021, scaling wind and photovoltaic power generation to 60% and 45% of annual demand, respectively, and utilizing existing hydropower synergy balance. The estimated power supply cost is $126 per megawatt hour, which is equivalent to the wholesale electricity price level in the past five years.Editor/Yang Meiling

• [EU sets new high for battery energy storage installation by 2025]
• In 2025, the EU will add 27.1 gigawatt hours of battery energy storage capacity, a year-on-year increase of 45%, setting a historical record. Since 2021, the total scale of energy storage in the European Union has surged from 7.8 gigawatt hours to 77.3 gigawatt hours, an increase of nearly tenfold. The report points out that public utility scale projects have become the main force, accounting for 55% of the annual new installed capacity, indicating a significant shift in market structure. To meet the energy flexibility needs by 2030, the EU needs to increase its energy storage capacity tenfold to approximately 750 gigawatt hours to support large-scale integration of renewable energy.Editor/Yang Meiling
