How to suppress the interference between power line carrier PLC and EMS?

Suppressing interference between the PLC and EMS via power line carrier communication requires time-domain peak shaving and frequency-domain isolation. In the time domain, coordinate the communication periods of the PLC and EMS to avoid simultaneous transmission. In the frequency domain, allocate a dedicated frequency band for the PLC, isolating it from the EMS's operating frequency band. Deploy filters at the linkage interface, such as setting the cutoff frequency of a low-pass filter to the PLC's highest frequency. Use shielded cables for connection, with the shield grounded at only one end. Analyze the interference spectrum through simulation to optimize the peak shaving strategy. In actual testing, the PLC communication bit error rate should be below 10^-5 at the moment of EMS startup. Suppressing linkage interference ensures reliable operation of the system within the energy management system.
