| Abstract |
In this paper, we propose a voltage regulation control algorithm in DC micro-grid using BESS. The BESS is installed at the load end of the DC micro-grid, and the bidirectional DC/DC converter measures the grid voltage in real time to autonomously charge/discharge without external communication. The sag and swell range of the grid voltage is set to (±)5% of the rated voltage, and a VR control algorithm for this case is proposed. The proposed algorithm is verified through simulation and experiment. |
