Bilborough 33/11kV站负荷容量受限

National Grid Electricity Distribution

Bilborough 33/11kV S Stn 的需求侧可用容量为 12.82132346，低于需求固化容量 23，当前 demandConstraint 为 amber，限制因素是 Thermal。发电侧则显示 generationAvailableCapacity 为 19.94415474，接近 generationFirmCapacity 20.63400078，且 generationConstraint 为 green，说明约束主要集中在负荷接入。由于该站暂无负荷或发电接入报价成交记录，现有容量状态将直接影响后续接入可行性与项目排队安排。

St Austell BSP电力容量信息

National Grid Electricity Distribution

St Austell BSP公布了其区域容量状态，需求侧可用容量为111.7807693，发电侧可用容量仅14.68180275。由于需求侧约束为绿色、发电侧约束为红色，信息显示当前瓶颈主要出现在热力发电能力。数据显示，负荷和发电连接申请的已接受与已提出数量均为0，意味着现阶段对新增接入的直接支撑能力有限。

自同步电压源逆变器同步频率共振抑制研究

OpenAlex

这项研究建立了考虑功率耦合的小信号模型，并提出通过串联带阻滤波器抑制自同步电压源逆变器中的同步频率共振。文章认为，共振会改变系统动态和稳态特性、加剧系统振荡，因此需要在不改动原有控制参数的情况下消除峰值。论文给出仿真和实验结果验证方法有效，且带宽更宽、响应更快，可减少对主动功率环和无功功率环的副作用。
