GFM逆变器在微电网黑启动中作用增强

U.S. Department of Energy OSTI

GFM逆变器在微电网黑启动和停电后重建中的作用被进一步强调，文章讨论了其在关键负荷供电中的应用。之所以变化，是因为微电网需要在脱离公用电网时保持独立运行，并在黑启动场景下提供快速启动及稳定电压、频率支撑。文中基于分析、仿真和实验指出，GFM逆变器可提升微电网恢复的可靠性与韧性，但控制策略、设备设计和系统要求仍是实施重点。

Warwick 11kV站点容量受热力约束

National Grid Electricity Distribution

Warwick 11Kv S Stn 的公开容量数据表明，该地区负荷侧可用容量为20.78560605，且 demandConstraint 处于 red。之所以出现这一状态，是因为 demandConstraintLimitingFactor 标注为 Thermal，说明限制来自热力约束而非发电侧。按当前数据，负荷侧 firm capacity 为60、generationAvailableCapacity 为28.83677864，已接受2个负荷接入报价共4.4，直接影响后续接入可用空间。

GFM逆变器提升微电网黑启动能力

U.S. Department of Energy OSTI

GFM逆变器在微电网黑启动和黑障后重启中的作用被进一步强调，文章聚焦其在独立运行、稳压稳频和关键负荷供电中的应用。之所以出现这一变化，是因为逆变器驱动的黑启动虽然可替代同步发电机，但在控制策略、系统设计和运行要求上带来新的挑战。文中指出，分析、仿真和实验结果显示，GFM逆变器是保障微电网可靠、韧性运行的核心环节，但其落地仍取决于控制软件与系统要求的匹配。

联邦LSTM用于社区微电网日前预测

U.S. Department of Energy OSTI

一项面向社区微电网的日前预测方法改用联邦式LSTM，在微电网控制器上聚合各业务端权重，用于规划能量共享。之所以这样设计，是因为社区微电网需要可靠的短期预测来安排调度或交易，同时又不希望暴露企业和住户的敏感用能数据。该研究以波多黎各Adjuntas一个3家企业的社区微电网为案例，并以控制器汇总敏感数据的中心LSTM作基线，作为面向网络化微电网的概念验证。

新算法提升微电网故障保护能力

U.S. Department of Energy OSTI

ORNL提出一种基于不平衡功率（Sunb）的故障检测算法，可在并网和孤岛两种模式下识别微电网故障，并判断故障类型。微电网保护在两种运行方式下故障特征不同，且需要兼顾协调性，因此作者用本地电压、电流不平衡量来提高检测效率。该方法对LG、LL和LLG故障表现出高灵敏度和选择性，并可在硬件在环平台上配合3台SEL 751继电器验证，且无需依赖通信网络的自适应整定。
