格拉斯伯里微电网容量信息更新

National Grid Electricity Distribution

格拉斯伯里在南威尔士66-11电压等级下的容量信息被更新，显示负荷与发电侧可用容量及约束状态。由于GSP Rassau G.S.P.、BSP Abergavenny Primary一带的接入与运行条件不同，系统给出了对应的供需能力数据。当前负荷可用容量为4.598360538、发电可用容量为14.1869173，且负荷和发电约束均为amber，直接影响后续接入判断。

Bedminster负荷受限、发电容量为绿

National Grid Electricity Distribution

Bedminster的主供区负荷可用容量为0，负荷约束状态为red，说明该区域新增负荷接入已受限；发电侧可用容量为13.18690968，发电约束状态为green。之所以出现这种差异，是因为摘要给出的负荷约束限制因素为Thermal，表明当前瓶颈在负荷侧接入能力而非发电侧。数据显示，loadConnectionOffersAcceptedCount为3、容量16.7，已发出的负荷接入报价为4个、容量7.187；这意味着后续项目更依赖接入条件和容量分配结果。

基于参数敏感性分析识别并网逆变器PLL参数

OpenAlex

Fei Li等提出了基于参数敏感性分析的并网逆变器PLL参数识别方法。该研究面向微电网与并网控制场景，旨在提高锁相环参数识别的准确性，减少控制参数不确定性带来的影响。论文发表于2024年6月26日的《IET Power Electronics》，目前公开信息未给出具体实验数据，但其方法可为并网逆变器控制器整定提供参考。

南威尔士Nantgarw电网接入能力数据公布

National Grid Electricity Distribution

南威尔士Nantgarw BSP区域的接入容量数据被列出，显示该网点当前可用能力处于受限状态。之所以呈现这一结果，是因为11kV侧负荷可用容量仅16.93102646，且负荷约束因素标注为Thermal。数据显示，发电可用容量为29.92121315、发电约束为red，而负荷和发电的已接受及已发出接入报价均为0，意味着后续新增接入仍受容量约束影响。

基于参数敏感性分析的并网逆变器PLL参数识别

OpenAlex

该文提出了面向并网逆变器的PLL参数识别方法，利用序列阻抗模型与实测数据构建识别函数，并通过粒子群优化求解。文章认为，在弱电网条件下，PLL是导致并网逆变器次同步振荡的主要原因之一，因此需要提高参数识别精度。文中称，该方法基于参数敏感性分析选取频率带，并在仿真和半实物实验中验证了可行性与有效性，可在相同测量误差下提升识别准确性。
