Core Viewpoint - The article highlights the contrast between the recent large-scale power outage in Spain and Portugal and the reliability of China's power grid, emphasizing the advanced technology and infrastructure in China that allows for rapid recovery from outages [1][3][4]. Group 1: European Power Outage - On April 28, Spain and Portugal experienced a massive power outage affecting over 50 million people, with Spain losing 60% of its power supply within 5 seconds [3][4]. - The outage lasted up to 20 hours in some areas, disrupting flights, train services, and communication systems, marking it as one of the largest outages in European history [3][4]. - The causes of the outage were attributed to the isolated nature of the Spanish and Portuguese power grids and a lack of effective renewable energy management technologies [3][4]. Group 2: China's Power Grid Reliability - China's power grid is interconnected nationwide, allowing for coordinated responses to local outages, which contrasts with the isolated grids in Spain and Portugal [4][6]. - The country has invested significantly in modernizing its power infrastructure, resulting in advanced technologies that enable rapid recovery from outages, such as the "FA" system that allows for power restoration in as little as 0.13 seconds [6][8]. - The integration of artificial intelligence in fault detection and recovery processes has improved efficiency and reduced human error in power management [8][9]. Group 3: Technological Advancements - The "FA" system, which stands for feeder automation, has been implemented in Ningbo, allowing for automatic fault isolation and restoration, significantly reducing outage times from hours to seconds [7][8]. - Continuous investment in technology and infrastructure has strengthened China's power grid, enabling it to handle a growing share of renewable energy sources effectively [9][13]. - The advancements in power grid technology are seen as crucial for maintaining stability and reliability, especially as the share of renewable energy increases [13].
