This paper presents a microgrid control strategy to unify the control topology for energy storage systems and renewable energy sources inverters in an ac microgrid and to protect the microgrid reliability from unintentional islanding instability using control loops, which use thedc link voltage as a feedback. This bounds the dc link voltage and provides reliable operation in the microgrid. Simulation validates the proposed control strategy, and experiment results extol the concept.

无意孤岛情景下微电网模式不间断转换的控制策略

本文提出了一种微电网控制策略，以统一交流微电网中储能系统和可再生能源逆变器的控制拓扑，并使用控制回路保护微电网的可靠性免受无意孤岛不稳定的影响，控制回路使用直流链路电压作为反馈。这限制了直流链路电压并在微电网中提供可靠运行。仿真验证了所提出的控制策略，实验结果对这一概念进行了验证。
