500V DC Renewable Microgrid

I was able to design 500V dc microgrid. The microgrid is powered by two renewable sources (PV and WT). The Microgrid has battery storage unit to achieve the dispatch concept to solve the dilemma of the intermittency of the renewable sources. The Microgrid can work in island mode and grid connected mode. In the first mode the battery regulates the voltage as long as it is connected and, in the grid, connected mode, the utility grid regulates the voltage. There is a MPPT unit with the PV & WT farms to guarantee the maximum power.
