摘要

作为整合可再生能源和增强系统弹性的一种手段，直流（DC）网络微电网已经获得了突出的地位。然而，这些类型的微电网严重依赖于通信网络，其固有的时间延迟会严重影响系统的稳定性。此外，各种通常为非线性的负载特性的存在使情况进一步复杂化。本文提出了网络微电网的时滞相关稳定性分析，特别关注主动负荷存在下的鲁棒运行。该公式还考虑了微电网内负荷的不确定性和变化性质。结果表明，主动负荷对可行工况、共识矩阵设计和控制器整定有更严格的约束。

Stability of Networking DC Microgrids with Active Loads

Direct current (DC) networking microgrids have gained prominence as a means to integrate renewable energy sources and enhance system resilience. However, these types of microgrids heavily rely on communication networks, whose inherent time delays can significantly impact system stability. Additionally, the presence of various, often non-linear load characteristics further complicates the scenario. In this paper, a delay-dependent stability analysis for networking microgrids is presented, with a specific focus on robust operation in the presence of active loads. The formulation also accounts for the uncertain and varying nature of loads within microgrids.The results show that active loads impose more stringent constraints on feasible operating conditions, consensus matrix design, and controller tuning.
