从“毛细血管”到“主战场”:配电网的角色之变与破局之路
中国能源报· 2025-12-05 10:52
12月4日,第六届全国地方电网与配电网圆桌论坛在北京人民日报社举行。本次论坛作为第八届中国能源产业发展年会的重要组成部 分,论坛以"融入全国统一电力市场,服务地方高质量发展"为主题,汇聚了政策研究者、行业专家与一线实践者,共同探讨地方电网 与配电网在新型能源体系中的关键作用与发展路径。 共识:"得配网者,得新型电力系统之未来" 配电网的转型升级,与国家"双碳"战略及能源发展格局息息相关。 目前,我国已成为全球最大的能源生产国和消费国,并且能源结构持续优化,清洁低碳转型步伐明显加快。在此背景下,"十五五"规 划建议进一步明确提出,要加快建设新型能源体系,建设能源强国。 中国国际经济交流中心能源与绿色低碳发展研究部部长、研究员景春梅指出:"配电网是能源转型和新能源消纳的主战场。" 景春梅具体阐释了配电网成为"主战场"的三重逻辑:其一,它是新能源消纳的"最后一公里";其二,它也是新型负荷汇聚的"最后一 公里";其三,它还是系统灵活性与韧性的"基层单元"。 如今,配电网已不再是电力系统的"配角",而是新型电力系统中不可或缺的"主角"之一。正因如此,景春梅直言:"得配电网者,得 新型电力系统之未来。" 这一判断与德国通 ...
专家谈配电网:增量配电网的市场主体地位落实不够

12月5日消息,在第八届中国能源产业发展年会地方电网与配电网圆桌论坛上,中国国际经济交流中 心,能源与绿色低碳发展研究部部长景春梅表示,配电网的发展与国家的双碳战略以及能源发展格局紧 密相关。配电网一直在我们电力市场的结构发出配售都是重要的一环,要用能源转型和新能源消纳的主 战场来定义它。她指出,未来"得配网者,得新型电力系统之未来"。 景春梅指出,从国家战略及有关文件的表述看,配电网功能在未来要实现四大转变。与传统的配电网相 比,要从原来电能单向输送,配送的通道变为能源资源的配置平台,要从无源网络向有源网络转变,从 被动响应、上级调度,向主动自制运行转变,从原来的技术封闭、信息孤岛,向数字底座数据集成中心 转变。 配电网何以成为能源转型和新能源消纳的主战场?景春梅表示,配电网是新能源消纳的最先一公里。配 电网是分布式风光就地消纳,避免远距离输送损耗的关键环节。电力通过电网输送,最后要经过配电 网,进入到千家万户、千行万业。电动汽车数据中心、智能家居、电采暖等一些新的高弹性的负荷,这 两年集中在用户侧,90%以上通过配电网接入。配电网承载80%的停电事故,微电网、虚拟电厂和V2G 新业态均以配电网作为物理载体 ...
大规模设备更新首批1730亿落地,哪些仪器/领域收益了?
仪器信息网· 2025-07-25 03:02
Core Viewpoint - The new large-scale equipment update and consumer goods replacement policy in China, initiated in 2024, is set to significantly boost economic development by expanding funding support and coverage areas, aiming for a 25% increase in equipment investment across seven major sectors by 2027 [1][5]. Group 1: Policy Dynamics and Key Points - The funding scale for equipment updates has been expanded to 200 billion yuan, with the first batch of approximately 173 billion yuan allocated to 7,500 projects across 16 sectors [2][5]. - The second batch of funding, amounting to 81 billion yuan, is being reviewed for projects focusing on consumer goods replacement and equipment updates [5]. - The 2025 policy introduces new support areas such as electronic information and safety production, creating a "16+N" coverage system [5][8]. Group 2: Implementation Mechanism Optimization - The policy has removed the previous investment threshold of 100 million yuan for projects, lowering the entry barrier for small and medium-sized enterprises [5][7]. - A dual review mechanism of "local audit + national review" has been established to streamline the approval process [5][7]. - New upgrade directions in the energy and power sector include ten specific areas, enhancing the efficiency and safety of energy facilities [8][9]. Group 3: Comparison of 2024 and 2025 Policies - The 2024 policy focused on seven key sectors, while the 2025 policy expands to 16 sectors with a dynamic expansion mechanism [7]. - The funding intensity has increased with an additional 81 billion yuan and a 1.5% interest subsidy on loans [7]. - The 2025 policy introduces 294 new national standards, enhancing the regulatory framework for project applications [7]. Group 4: Key Supported Areas and Renovation Focus - Major industrial sectors targeted for equipment updates include petrochemicals, steel, non-ferrous metals, and machinery, focusing on replacing outdated equipment and upgrading production lines [8][10]. - Energy facilities will see upgrades in areas such as high-efficiency energy motors and waste heat recovery systems, aimed at reducing energy consumption [8][10]. - Transportation infrastructure will undergo significant updates, including intelligent systems for railways and urban transit, enhancing operational efficiency [10][11].
