Tavistock电网接入容量为零

National Grid Electricity Distribution

Tavistock主区33-11电压层级的需求可用容量为0，需求约束标记为red，说明该区域新增负荷接入已受限。之所以出现这一状况，是因为需求约束限制因素显示为Thermal，表明现有网络能力不足以支撑进一步接入。同期该区generationAvailableCapacity为8.036938667、generationConstraint为green，而loadConnectionOffersMadeCount仅为1、容量1.5，直接反映负荷接入机会稀缺。

Southway微电网容量受热电限制

National Grid Electricity Distribution

Southway地区的需求与发电可用容量信息发生更新，需求端可用容量为7.504427433，发电端可用容量为4.626596928。由于系统约束分别由热电机组和负荷条件主导，说明该区域接入能力仍受现有网络和机组条件限制。数据中需求可用容量22.74900055、发电可用容量9.119999886，且负荷与发电接入报价接受和发出数量均为0，意味着短期内新增接入空间有限。

孤岛微电网提出去中心化电压控制方法

OpenAlex

该论文提出一种用于孤岛微电网的去中心化二次电压控制与不平衡电压补偿方法。由于岛状微电网需要在分散条件下维持电压稳定并处理电压不平衡，文章围绕控制协同问题展开。文中仅给出论文题目和会议来源，未提供性能指标、实验数据或应用规模，因此其工程效果和落地影响还无法据此判断。

Dudley 132/11千伏站负荷接入容量仅2.76

National Grid Electricity Distribution

Dudley 132/11Kv站点的负荷可用容量为2.764833927，已发出并接受1项负荷接入报价，容量1.05；发电可用容量为21.9166317，未见发电接入报价。West Midlands区域、132-11电压等级和Penn 132Kv S Stn所对应的边界条件共同决定了该站点当前接入空间。数据显示负荷约束为红色、限制因素为Thermal，而发电约束为绿色，说明后续新增负荷接入将直接受热约束影响。

孤岛微电网提出分散式二次电压控制方法

OpenAlex

一种面向孤岛微电网的分散式二次电压控制与不平衡电压补偿方法被提出。由于该方法基于小交流信号注入，作者希望在无需独立通信链路的情况下，同时完成电压稳定和不平衡补偿。文中称该方法仅用一个注入信号即可实现两项功能，降低PCC总谐波畸变，并在PCC估计不准确时仍有效，仿真和实验结果验证了其可行性。

苏利电网需求与发电容量受限

National Grid Electricity Distribution

苏利电网在South Wales的132-11kV BSP区域显示，需求可用容量为104.727684，低于需求固化容量158.6699982，发电可用容量25.6567173也低于发电固化容量30，且两项约束均标红。由于热电出力成为限制因素，系统当前在需求和发电两端都出现容量紧张。数据还显示负荷和发电接入要约已分别为0与1宗，发电接入要约容量38.5，直接反映后续接入安排仍受约束。

虚拟同步发电机微电网低频振荡控制提出分布式方法

OpenAlex

这篇论文提出了面向低压孤岛式多母线微电网的分布式低频振荡抑制控制，用于缓解虚拟同步发电机并联系统中的振荡问题。文章认为，现有低频振荡分析忽视了微电网所需的频率变化率和稳态有功-频率特性，导致对阻尼设计的实际约束考虑不足。文中给出DLFOD控制，并称其可保证RoCoF和P-f特性、具备线性结构，且已通过理论分析、实时仿真和实验验证。
