1. A low-level unidirectional global communication method for DC microgrids comprising:
injecting at least one sinusoidal component into DC microgrid power lines;
relating at least one parameter and at least one command with frequency components;
including at least one communication structure for at least one communication protocol;
providing a detection method for detecting the at least one injected sinusoidal component; and
all without requiring hardware modification to the DC microgrid; and
wherein a frequency range of the at least one sinusoidal component is rejected by a converter engaged with the DC microgrid power lines.
