Core Viewpoint - The recent large-scale power outage in Spain and Portugal highlights the importance of reliable power supply systems, contrasting with China's advanced and interconnected power grid capabilities [3][5][15]. Group 1: Power Outage in Europe - On April 28, Spain and Portugal experienced a massive power outage affecting over 50 million people, with some areas experiencing outages for up to 20 hours [3][5]. - The outage was attributed to the isolated nature of the Spanish and Portuguese power grids, which lack strong interconnections with other European countries [3][5]. - High reliance on renewable energy sources, such as solar (53%) and wind (11%), without adequate storage solutions made the grid vulnerable to extreme weather conditions [3][5]. Group 2: China's Power Grid Reliability - China's power grid is described as reliable and interconnected, allowing for coordinated national responses to local outages [5][7]. - The country has invested significantly in modernizing its power infrastructure, resulting in advanced technologies that enhance grid stability and reduce outage durations [11][15]. - The implementation of self-healing technologies has drastically reduced power restoration times from hours to milliseconds, exemplified by a recent incident where power was restored in just 0.13 seconds [7][8][11]. Group 3: Technological Advancements - The development of automated fault isolation systems has improved the efficiency of power restoration, with success rates increasing from 77.32% to 91.41% [7][8]. - The use of artificial intelligence for fault detection and isolation is expected to further enhance the automation of the power grid, minimizing human error [11][15]. - Continuous investment in technology and infrastructure has positioned China's power grid to handle the complexities introduced by distributed renewable energy sources [15]. Group 4: Personal Story of Zhang Jiming - Zhang Jiming, a power worker recognized for his contributions, has a background of overcoming personal challenges, which has shaped his dedication to his work [13][15]. - His journey from a technician to a leading expert in power grid automation reflects the importance of continuous learning and adaptation in the rapidly evolving energy sector [15]. - Despite newfound fame, Zhang remains committed to his responsibilities, emphasizing the critical role of power workers in ensuring reliable electricity supply for the public [15].
