Virtual Oscillator Control as Applied to DC Microgrids with Multiple Sources

Simple reference-frame transformations allow to implement the method of Virtual Oscillator Control, originally conceived for AC microgrids, to parallel-connected converters in a DC microgrid network. As a result, based only on local measurements and without recourse to a communication link, the DC-DC converters in the microgrid share the load power in proportion to their power ratings without circulating currents, and may be readily interleaved. Simulations validate the proposals for a set of three half-bridge converters serving a common DC load
