As the smart grid will add flexibility to the electric power system and increase network reliability, this project is concerned with preparing a solid protection system to protect the network from error and return it to a normal state in a short time. Relays will reduce outages and their consequences, ensure quick network recovery, and make the electric power system more prepared for emergencies. A set of relays and circuit breakers were added to the network and programmed with Arduino before being connected to the ESP32 piece, with the working status displayed on the display screen.
