Abstract
The present invention relates to sinusoidal components representative of particular commands (VCMD) or values, or a combination thereof, superimposed on DC power lines (VDC) as a means of communication between the prosumers wherein the communication will be tailored to commands for microgrids.
Claims14
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;
