能源强国建设“大家谈”︱确保新形势下大电网安全 筑牢能源强国根基

Core Viewpoint - The article emphasizes the importance of ensuring the safety of the large power grid as a foundational element for building an energy powerhouse in China, highlighting the need for a comprehensive approach to address the challenges posed by the transition to a new energy system [2][5][8]. Group 1: Achievements in Energy and Power Development - Since the beginning of the new era, China has achieved remarkable progress in energy and power development, with a total installed power generation capacity reaching 3.79 billion kilowatts by November 2025, approximately 3.3 times that of 2012 [3]. - The country has built the world's largest and highest voltage hybrid AC/DC power grid, with a transmission capacity of 340 million kilowatts for the "West-to-East Power Transmission" project [3]. - The transition to green energy has been significant, with installed wind and solar capacity exceeding 1.76 billion kilowatts by November 2025, over 27 times that of 2012, accounting for 46% of total installed capacity, making it the largest source of power generation [3]. Group 2: Higher Requirements for Grid Safety - As China transitions from an energy power to an energy powerhouse, the safety of the large power grid is critical, serving as the core foundation for this transformation [5]. - The new energy system is expected to have over half of its installed capacity and non-fossil energy generation by 2030, with wind and solar capacity targeted to reach 3.6 billion kilowatts by 2035 [5]. - The construction of a new power system is essential for achieving carbon neutrality goals, with electricity playing a leading role in this transition [5]. Group 3: Challenges Facing Grid Safety - The shift from a fossil fuel-dominated power structure to a new energy-dominated one presents complex safety challenges for the large power grid, which will increasingly rely on renewable energy sources [6][7]. - The characteristics of the grid are changing, with a transition from a dominant main grid to a collaborative high, medium, and low voltage structure, complicating safety operations [7]. - The integration of high levels of renewable energy introduces uncertainties and requires a re-evaluation of power balance mechanisms and stability [6]. Group 4: Ensuring Grid Safety - Ensuring the safety of the large power grid is a systematic project that requires enhancing safety governance capabilities and constructing a comprehensive safety governance system [8]. - Key strategies include improving planning capabilities, enhancing technological innovation, and establishing a robust legal framework to support the development of the new energy system [9][10]. - The article outlines six key areas for improvement, including planning, technological innovation, legal support, standardization, operational management, and regulatory oversight to ensure the safety of the power grid [9][10].
