Group 1 - The core viewpoint of the article emphasizes the development of an integrated power source, grid, load, and storage system in Wuhan, aiming to enhance the city's energy infrastructure [1] - The proposal includes accelerating the construction of a robust digital smart grid and developing new models such as green electricity direct connection and microgrids [1] - Continuous efforts will be made to promote electrification, gasification, and hydrogenation along the Yangtze River, with the goal of creating a world-class urban power grid [1]

Core Viewpoint - The rise of trade protectionism, the COVID-19 pandemic, and the energy crisis caused by the Russia-Ukraine conflict have created unprecedented challenges for energy security. The Global Energy Internet Development Cooperation Organization, initiated by China, emphasizes that a smart and robust grid is key to building a new power system and energy framework, serving as an important pathway for global energy internet construction [1][2]. Group 1: Smart and Robust Grid Concept - The smart and robust grid is defined as a new type of grid that integrates ultra-high voltage and distribution networks as its physical foundation, driven by the deep integration of power grid technology and digital intelligence technology [2]. - The core connotation of the smart and robust grid is reflected in "four new" aspects: new network forms, new digital dynamics, new development hubs, and new cooperation platforms [2]. - Key features include "six strengths": strong climate resilience, strong safety and flexibility, strong adjustment capability, strong security assurance, strong intelligent interaction, and strong interconnection [2]. Group 2: Importance and Development of Smart and Robust Grid - The smart and robust grid can provide a strong platform for efficient utilization of renewable energy and broad access for diverse power generation and consumption entities [2]. - It is essential for enhancing grid strength, quickly addressing various faults, and ensuring stable operation of power systems under extreme conditions such as climate disasters [2]. - The construction of the smart and robust grid is seen as a major trend and a systematic project that requires the advancement of three constructions: strong main grid framework, distribution microgrid construction, and adjustment capability development [2]. Group 3: Future Outlook and Global Context - The smart and robust grid is expected to reshape the human energy system, with all energy supply coming from clean energy sources, and will present a new form that integrates various energy sources and technologies [3]. - The Global Energy Internet Development Cooperation Organization aims to promote the construction of a global energy internet to meet global electricity demand in a clean and green manner [3]. - The development of the smart and robust grid is supported by a solid foundation globally, with numerous innovative demonstrations emerging in areas such as flexible transmission, digital twins, and smart scheduling [6].
