AI 中文摘要
电气化被规划为一个网络问题：需求增长、上游容量提升、本地资源等待强化。我们认为，资金与时间成本中的相当一部分源于架构而非电气化本身，因此提出将短电网（Short Grid）作为部署单元：由本地控制的建筑、街区或园区，其需求、发电、储能及本地市场均在能源路由器（Energy Routers）之后运行，该路由器执行与长电网（Long Grid）的核准连接 envelope（交换边界）。由于该边界管控的是交换量而非装机容量，本地资源可随光伏（PV）与电动汽车（EV）的安装节奏并行扩展，无需等待电网强化。当前光伏与电动汽车电池是主力，但该架构具有通用性：任何固定或移动的发电或储能资源均可适配同一边界与接口。能源网络运营商（EnergyNet Operators）协调短电网之间及与长电网的交换，保护功能保持本地；车对能源网络（Vehicle-to-EnergyNet, V2EN）与基于移动性的能源对等（Mobility-Based Energy Peering, MEP）使移动性驱动的电池可在短电网内部及之间接入；基于优先级的运行机制在短缺时保护关键服务。我们在模型中测试了该架构，尚未开展实地测试：包括瑞典隆德的10栋建筑社区、斯坦福与半月湾的公交关联微电网对，以及纽约洛克威的拟议20站点网络。家庭与服务是瑞典、丹麦、挪威、加利福尼亚及纽约的最大需求类别（484太瓦时/年），将其电网进口减半约为242太瓦时。欧洲至2040年的电网投资预计超1.2万亿欧元，建模显示其取决于系统设计。负电网价值（Negagrid value）效仿负瓦（negawatt），衡量避免、缩小或推迟的电网投资，扣除本地替代成本后的净值。核心原则是“不重复付费”：优先构建协调的本地能力，仅对剩余需求强化长电网。
英文摘要
Electrification is planned as a network problem: more demand, more upstream capacity, local resources waiting for reinforcement. We argue that a material part of that bill, in money and time, follows from architecture, not electrification itself, and propose the Short Grid as the deployment unit: a locally controlled building, block or campus whose demand, generation, storage and local market operate behind Energy Routers enforcing an approved connection envelope to the Long Grid. Because the envelope governs exchange, not installed capacity, local resources can grow and many sites can build in parallel at the pace of PV and EV installation, not grid reinforcement. PV and EV batteries dominate today, but the architecture is general: any generation or storage, fixed or mobile, fits behind the same boundary and interfaces. EnergyNet Operators coordinate exchange among Short Grids and with the Long Grid; protection stays local; Vehicle-to-EnergyNet (V2EN) and Mobility-Based Energy Peering (MEP) make mobility-financed batteries accessible within and between them; priority-based operation protects critical services in shortage. We test it in models, not yet the field: a ten-building neighbourhood in Lund, Sweden; a bus-linked microgrid pair at Stanford and Half Moon Bay; and a proposed 20-site network in Rockaway, New York. Households and services are the largest demand category in Sweden, Denmark, Norway, California and New York (484 TWh/yr); halving their grid imports would be about 242 TWh. Europe's network investment to 2040 is estimated above EUR 1.2 trillion; modelling shows it depends on system design. Negagrid value, following the negawatt, counts network investment avoided, downsized or deferred, net of local substitute costs. "Don't pay twice": build coordinated local capability first; reinforce the Long Grid for what remains.
