Distributed generators performing black start to form isolated microgrids offer a flexible and resilient solution to service restoration in distribution systems. Employing the dynamic microgrid concept, distributed generators can form isolated microgrids by changing their physical boundaries through smart switches and conventional circuit breakers. However, the flexibility of distributed generators has not been thoroughly investigated and utilised in existing works. To address this issue, this letter presents a new model to the reconfiguration formulation in active distribution networks considering different operation modes of distributed generators. Compared with the existing models, this study provides a new formulation supporting different DGs’ operation modes and fully making use of their flexibility. Illustrative results on IEEE 34-test systems verify the effectiveness of the proposed model.

动态边界配电网中分布式发电的灵活运行


分布式发电机执行黑启动以形成孤立的微电网，为配电系统中的服务恢复提供了灵活且有弹性的解决方案。采用动态微电网概念，分布式发电机可以通过智能开关和传统断路器改变其物理边界，形成孤立的微电网。然而，分布式发电机的灵活性在现有工作中尚未得到彻底研究和利用。为了解决这个问题，本文提出了一种考虑分布式发电机不同运行模式的主动配电网络重构公式的新模型。与现有模型相比，本研究提供了支持不同DG运行模式并充分利用其灵活性的新表述。 IEEE 34 测试系统的说明性结果验证了所提出模型的有效性。
