Abstract |
This paper proposes a fully decentralized control scheme for hybrid AC/DC microgrids. It proportionallyshares the loads in a hybrid AC/DC microgrid among its sub-grids. By controlling the interlinkingconverters as voltage source inverters, the scheme enables the hybrid microgrid to operate with or withoutAC sources. It is possible to shut down all the power sources in the AC sub-grid to minimize the fuelconsumption. Moreover, any fault in the AC sources will not cause the collapse of the entire AC sub-grid.Consequently, the hybrid microgrid under the control scheme can have higher efficiency, reliability andflexibility as compared to the existing decentralized schemes. |
