The screen is the EMS system web screen of the test bad using IEC 61850 standard, the left side is a photo attached to the paper, and has now been upgraded to the right side screen.
The web shows the current and voltage measurements of three DC loads from No. 1 to No. 3.
The AC-DC Relay indicates what power is currently used, and the AC-DC can be switched by controlling the relay through the button.
In addition, the voltage and current measurements of power generation can be checked in the PV Pannel, and the Battery Condition can be seen.
The EMS system can centrally control the power of the entire building in the future, and it is expected that automatic AC-DC conversion can solve the power quality problem of the existing microgrid by system-connected, enabling efficient energy management.
In addition, surplus power generated from the photovoltaic energy of DC nanogrid can be easily traded in the power brokerage market.
