Abstract:
1. A Direct Current (DC) micro-grid, comprising: at least one power generator coupled to at least one power generation bus; at least one energy storage device coupled to at least one energy storage bus; at least one load coupled to at least one load bus; a common DC bus; a first power electronics device configured to provide power transfer coupling the at least one power generation bus to the common DC bus; a second power electronics device configured to provide power transfer coupling the at least one energy storage bus to the common DC bus; a third power electronics device configured to provide power transfer coupling the at least one load bus to the common DC bus; a second power generator coupled to a second power generation bus; a second energy storage device coupled to a second energy storage bus; a second common DC bus; a fourth power electronics device configured to provide power transfer coupling the second power generation bus to the second common DC bus; a fifth power electronics device configured to provide power transfer coupling the second energy storage bus to the second common DC bus; and a sixth power electronics device configured to provide power transfer coupling the at least one load bus to the second common DC bus.
