East Leake变电站负荷与发电容量受限

National Grid Electricity Distribution

East Leake 33/11kV变电站的负荷与发电容量约束情况发生了变化，当前负荷可用容量为6.345478769，发电可用容量为0。原因是该站点在东米德兰兹区域的接入约束已被标记，负荷约束为amber，发电约束为red，限制因素均为Thermal。数据还显示，已接受1项负荷接入申请、容量1.183，而发电接入申请和已发出报价均为0，意味着新增发电接入受限更明显。

Grantham 33千伏变电站容量信息

National Grid Electricity Distribution

Grantham 33Kv S Stn 的电力接入容量信息显示，需求侧可用容量为 59.88794334，受热力约束为绿色；发电侧可用容量为 15.77345181，受热力约束为红色。之所以出现这一状态，是因为该站点的接入能力受网络容量限制，且发电侧约束更为明显。数据显示，已接受 1 项负荷接入申请、容量 17.088，而发电接入申请为 0，说明短期内负荷接入机会仍在，但发电接入空间有限。

Northampton West变电站容量约束信息

National Grid Electricity Distribution

Northampton West 132/33/11Kv站点显示电力接入能力受限，需求侧可用容量为20.47133954，发电侧可用容量为7.547092438。之所以呈现这一状态，是因为需求约束标记为green、发电约束标记为red，且限制因素均为Thermal。当前没有已接受或已提出的负荷、发电连接申请，意味着后续接入仍取决于网络容量释放。

切斯特菲尔德33千伏供电容量信息更新

National Grid Electricity Distribution

切斯特菲尔德33Kv区域的供电容量信息显示，需求和发电两类容量均已接近上限，但状态不同。之所以如此，是因为需求侧约束为绿色、发电侧约束为红色，且限制因素都标注为Thermal。该区域demandAvailableCapacity为39.16043792、generationAvailableCapacity为38.7408371，generationConnectionOffersAcceptedCapacity为30.149，意味着后续接入更受现有热容量约束。

宽带广义电网阻抗识别提出SNR设计方案

OpenAlex

论文提出了用于宽带广义电网阻抗识别的信噪比设计方案，以提升识别准确性。文中指出，弱电网条件下电力与并网逆变器之间的阻抗失配导致振荡事故上升，广义电网的宽带特性使精确识别更为紧迫。作者在MATLAB/Simulink平台和RT-BOX平台上通过比较实验验证了该方案对扫描广义电网时识别精度的帮助。
