Abstract

Techniques for power sharing in DC networks using virtual impedance frequency droop control are provided. In one aspect, a method for power sharing in a DC network having multiple electrical energy generation sources connected to at least one load includes the steps of, at each of the electrical energy generation sources: generating a controllable DC voltage; superimposing a controllable AC signal on top of the DC voltage; regulating the AC signal using virtual impedance frequency droop control; and determining a desired DC voltage output using the regulated AC signal. The DC voltage can then be regulated to match the desired DC voltage output. A system for power sharing in a DC network is also provided.
