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
