Chaddesden变电站负荷容量受热力约束

National Grid Electricity Distribution

Chaddesden 33/11kV变电站的负荷可用容量为3.766447653，负荷约束状态为amber，限制因素为Thermal。之所以出现这一状态，是因为该站在East Midlands承担33-11kV区域供电，负荷已接近可承载水平。数据显示，demandFirmCapacity为20、generationAvailableCapacity为15.16829395，且已发出2个负荷接入报价、合计2.868，直接影响后续接入项目安排。

网形成与跟网逆变器频率稳定性分析设计

OpenAlex

这篇论文提出了一套用于配置网形成和跟网逆变器参数的解析方法，以保证各母线频率轨迹稳定。之所以需要这类设计，是因为可再生能源并网增加、化石燃料同步机组下降，会削弱电网惯量并提升失稳风险。文中给出与频率偏差、RoCoF和稳定时间对应的闭式公式，并在修改后的IEEE 14母线系统EMT仿真中验证。

Laneast微电网容量受热力约束

National Grid Electricity Distribution

Laneast区域的需求侧可用容量为5.005576134，需求约束为amber；发电侧可用容量为4.00884676，发电约束为red。由于约束限制因素均指向Thermal，说明当地接入与运行能力仍受热力条件制约。当前已接受的负荷接入报价为0、已发出的为1宗1.072，新增接入仍取决于后续容量释放。

研究提出GFM与GFL频稳参数化方法

OpenAlex

研究提出一种对Grid-Forming（GFM）和Grid-Following（GFL）逆变器进行参数化设计的方法，使各母线频率轨迹在偏差、RoCoF和稳定时间上保持稳定。之所以需要这样做，是因为新能源并网增加、化石燃料同步机减少会降低电网惯量，系统失稳风险上升，而GFM与GFL的组合应用参数仍不清晰。文中给出闭式方程，推导出下垂斜率、滤波带宽和锁相环带宽，并通过改造后的IEEE 14-bus网络EMT仿真验证分析近似与仿真结果一致，说明该方法可用于微网和高比例新能源系统设计。

西米德兰兹一电网区域负荷受热力约束

West Midlands 的 Star Aluminium 33/11Kv 区域负荷可用容量为 0，demandConstraint 标为 red，限制因素为 Thermal。该区域发电侧可用容量为 11.84004974、firm capacity 为 16.5189991，说明现有电源仍有余量，但负荷接入已受约束。按 2026-08-09 记录，28.12199974 的 demandFirmCapacity 与 0 的 demandAvailableCapacity 形成对比，后续负荷接入和项目落地将取决于网络热容量是否释放。

Metheringham变电站容量受限

National Grid Electricity Distribution

Metheringham 33/11kV S Stn的需求侧和发电侧均处于红色约束状态，现有可用容量明显不足。由于站点的限制因素均标注为Thermal，说明当前瓶颈来自热稳定或热容量约束。该站需求firm capacity为18、available capacity为8.228929481，generation firm capacity为78.36299896但available capacity为0，直接限制新增负荷和电源接入。

Sawles Road配网容量数据更新

National Grid Electricity Distribution

Sawles Road所在区域的配网容量信息显示，33-11电压层级下需求和发电可接入能力分别为18.36527061和3.141813755。由于该区域的容量约束分别被标注为绿色和琥珀色，说明不同方向的接入余量并不一致。数据还显示，当前无已接受或已提出的负荷、发电连接申请，对后续项目接入节奏形成直接参考。

Tregaron主网供电能力与发电余量较低

National Grid Electricity Distribution

Tregaron所在主网区域显示，33-11kV层级的供电能力和发电余量都偏紧。原因在于该区域的需求与发电约束均由热力设施限制，导致可用容量受限。数据显示，需求firm capacity为13、available capacity为8.495605469，发电firm capacity为10、available capacity仅0.705941617，接入报价数量为0，后续新增接入空间有限。
