Introduction to hybrid AC/DC microgrids

In the DC micro-grid, electricity is transferred form one position to another via DC bus. The conversion of electricity from DC to AC is done by converter due to the presence of single bus (Loh et al., 2013, Loh et al., 2013). ("Autonomous Control of Interlinking Converter with Energy Storage in Hybrid AC-DC Microgrid," 2013) When there is

The Rise of the DC Coupled Microgrid

For a microgrid, the implications of being able to capture clipped energy are significant. Specifically, it means that a solar array and battery that are much larger than the inverter can be used, and the solar and battery can be optimally sized to service the continuous load of the microgrid without necessarily having to choose overly large inverters.
