Abstract :
This paper introduces a new operation method with coordinated droop control for stand-alone DC micro-grid. The proposed coordinated droop control can offer improvement of system reliability and efficiency for the stand-alone DC micro-grid, which is composed of DGs(distributed generations) and battery with SOC(state of charge) management system. The operation of stand-alone DC micro-grid with proposed control was analyzed with computer simulation. Based on simulation results, a 3kW hardware simulator was built and tested to analyze the performance of proposed system. The developed simulation model and hardware simulator can be utilized to design the actual stand-alone DC micro-grid and to analyze its performance.
