Low Voltage DC Microgrid Systems have attracted lot of attention in recent years due to its proposed use in smaller microgrids mostly based on renewable energy sources like PV arrays, fuel cells and microturbines. AC power grids have disadvantages like synchronization issues, reactive power control and bus stability which are overcome in DC grids. However, protection has been a challenge for these dc systems. Several strategies are suggested by researchers to overcome this problem. This paper gives brief about the strategies proposed to protect dc-microgrids by highlighting its relative advantages and disadvantages over one another. A solution is proposed thereafter which gives insight into fault tolerant approach to low voltage dc- bus system thus make it more acceptable
