为了提高微电网并网和孤岛两种模式切换的平滑性,增加其运行的可靠性,对基于Multi-agent系统理论的微电网控制模型进行了深入的研究,提出了新的控制模型。该模型增加了孤岛检测agent,根据电压和频率的变化及时判断孤岛的出现,使各微源可以迅速选择各自的控制方式,在实现微电网局部自治和保证微电网运行的安全性和可靠性的基础上,提高了微电网控制系统的快速反应能力。试验仿真结果证明了新模型的可行性和有效性。

In order to improve the smoothness of the micro-grid during switching between grid-connected mode and island mode, and enhance the reliability of the operation, the micro-grid control model based on theory of multi-agent system is researched in-depth, and the new model is proposed. The island detection agent is added in new model, the appearance of the island can be judged timely in accordance with the variation of voltage and frequency and each micro source can quickly select their control mode. On the basis of implementing micro-grid local autonomy, and ensuring security and reliability of micro-grid operation, the high speed response capability of the micro-grid control system is increased. The results of experiment and simulation verify the feasibility and effectiveness of the new model.
