作者 唐娟 刘甜 查姿伊

常州武进区礼嘉镇何墅村整村光伏项目近日并网运行。村民只提供屋顶,就能拿到一次性初装费和每年稳定租金。国网常州供电公司采用“800伏集中汇流、10千伏中压并网”的接入方案,显著提升电能质量和供电可靠性。项目不大,却触到了一个现实问题:绿电开发的空间往哪里找?

常州是全国唯一同时拥有国家碳达峰试点、国家级零碳园区建设、国家车网互动规模化应用试点、国家新型电力系统建设能力提升试点四张“国家名片”的城市。工业用电量占比居江苏省前列,高峰负荷破千万千瓦已成常态,一次能源对外依存度高,保供与降碳压力叠加。四张名片指向同一道考题:散落在园区、景区、村庄、公交场站的末端资源,能不能被组织起来、调得动、用得绿。常州的答案,落在微电网这个新型电力系统的“最小单元”上。

从一间屋顶到一张网

何墅村的项目,村民不用掏钱,村委统一组织屋顶开发,电网企业解决并网技术问题。切口在屋顶,指向的是分布式光伏“整村连片开发”如何落地。

在溧阳高新区创智园,江苏省内规模最大的近零碳智慧园区微电网正在运行。6200千瓦屋顶光伏、2500千瓦/4572千瓦时储能系统、智能充电桩、蓄冷蓄热能源站,由一个“智慧大脑”实时监测每一度绿电的去向和降碳数据。年综合收益超720万元,园区企业等效度电成本降低0.25元。

南山竹海景区,1120千瓦光伏车棚与173个充电桩构成站网互动微电网,推行潮汐定价,用价格杠杆撬动充电排长队痛点。常州交通车网互动智慧微电网综合能源站,聚合660千瓦可调度资源池,是当前江苏省公交领域功率规模最大、聚合度最高的车网互动枢纽节点。移动的车轮,在这里变成了微电网的“充电宝”。

目前,常州已构建覆盖车网互动、建筑能效、工业企业、园区源网荷储等场景的微电网集群。

从聚起来到调得动

聚起来只是前提。今年8月,江苏省开展2026年迎峰度夏负荷快速响应市场化错峰实战演练。在允许参与的调用范围内,常州5家直控型虚拟电厂有效错峰负荷占全省直控型虚拟电厂有效错峰量的一半以上。

支撑这一表现的是2024年建成的江苏省首家市级虚拟电厂管理中心。荷端调节资源管理平台以微电网为主要汇集单元,重点聚合储能、光伏、充电桩、5G基站等可调节资源,实测最大调节能力32.6万千瓦。常州培育的虚拟电厂运营商已从2024年的9家增至29家,聚合用户3914户,增幅超312%。

聚合与调节能力提升后,新的供需矛盾浮现。供给侧,全市工商业好开发、好消纳的屋顶基本铺满;需求侧,随着零碳园区、零碳工厂建设提速,出口制造企业对“可核验、可物理溯源”绿电的需求前所未有。常州依托自主研发的“以荷定源”AI工具,先建立有绿电需求的企业储备库,再找电源,智能输出源荷匹配方案。国网常州供电公司运用“以荷定源”智能圈选,锁定晶品光电3公里外国茂减速机光伏电站,促成发电方与用电方在省电力交易中心达成双边协议,让绿电直达、物理可溯源。

从“用好每一度电”到“用好每一抹绿”,常州微电网的功能边界正在被重新书写。当电力消费者变为“产消者”,当城乡的屋顶与水面接入一张智慧协同的绿电网络,常州以微电网的实践,为新型电力系统建设探出一条可复制、可推广的路子。

Open Questions

  • 微电网未来在更大范围推广的资金成本如何平衡?
  • 虚拟电厂参与市场化交易的长期机制如何完善?

Free Lecture》Restarting nuclear power is not the solution to AI’s electricity consumption~

With the development of AI data centers and semiconductor industries, Taiwan's demand for electricity has increased. Li Sichuan, the New Taipei mayor candidate of the Kuomintang, advocates extending nuclear power or restarting Nuclear IV. Author Lin Renbin believes that public policy must first clearly calculate the demand, compare various power supply options, and explain the cost, time schedule, nuclear waste disposal and final responsibility. "As long as it is safe" cannot be used as the policy answer.
