摘要/Abstract

摘要： 对于以可再生能源发电为主的微电网系统，直流微电网以显著优势成为新的研究热点。针对目前已有直流微电网控制的不足，采用了基于直流母线电压信号（ＤＢＳ）的协调控制策略，简化了控制结构，避免了通信线路的建设；完善了系统结构，加入对微型燃气轮机的控制；对直流微电网的运行模式进行了分析，设计了各分布式电源的优先级别和输出特性，实现了运行模式之间的平滑切换；最后在Matlab/Simulink中搭建了直流微电网仿真模型，对其在各种运行状态进行了仿真验证，结果表明所采用的控制方法能够实现直流微电网的协调控制。

Abstract: For microgrid systems with renewable energy generation, DC microgrid becomes a new hotspot for its significant advantages. Based on DC Bus Signaling(DBS), a coordinated control strategy is proposed to simplify control structure and avoid communication line construction. The proposed method improves system architecture by adding microturbine control. After analysis of different operation modes of DC microgrid, priority level and output characteristics of each distributed energy source are designed to switch smoothly among different operating modes. Various operation mode simulation results in matlab/simulink show that proposed method has ability to realize coordinated control of DC microgrid．

Key words: DC microgrid, coordinated control, DC bus signaling, microturbine, droop control
