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。

湖南大学团队针对带网支撑控制的网跟随逆变器，提出了一种稳定性定量分析和基于多电压前馈的增强方法。文章认为，GSC虽然能为电网提供惯量和电压支撑，但在弱电网下会削弱稳定性，因此需要先揭示失稳机理再改进控制。文中建立dq坐标系导纳模型，指出GSC引入三条耦合路径并显著放大导纳幅值，仿真和实验结果验证多电压前馈可抑制中高频振荡、改善稳定性。

美国陆军发布《Microgrid Handbook for Army Resilience: A Technical Review》，面向陆军基地领导介绍微电网的组成、融资、运行及相关监管和技术考虑。之所以编写这份技术综述，是因为陆军希望其设施尽可能独立、高效地运行，获得不受外部自然或人为事件限制或切断的安全能源与水资源。文中称微电网是实现驻地安全供电的有效方式，但未给出具体项目、投资额或性能数据，直接影响主要体现在基地规划、设计和实施决策上。

该研究提出一种面向多楼宇交流微电网的分层控制系统，以提升惯量表现并增强对通信延迟的抗扰能力。原因在于微电网在并网和孤岛两种运行模式下都需要更稳的频率、电压与功率分配控制。文中给出基于VSG的一级控制、加入Smith Predictor的二级控制以及三级有功无功分配控制，并通过MATLAB Simulink仿真验证其在两种模式下的运行效果。

圣地亚哥燃气电力公司在Borrego Springs微电网中验证了由100%可再生、基于逆变器资源执行黑启动和孤岛运行。之所以推进这一方案，是因为项目通过设备升级和控制器集成，把岛屿领导能力从柴油机切换到电池逆变器，以降低对传统发电资源的依赖。项目用现场测试、同步相量数据和硬件在环仿真验证了多储能系统协同控制，且该控制策略已被部署到其他微电网站点，说明方案具备复制性。
