Power Grid Control System Using GSM Modem Projects works on GSM wireless technology and 8051 micro controller. This application works for seven power grids. This system works by sending message to the GSM modem and it will communicate with MCU which will check is the number whether it is authorized or not and if the number is from authorized user grid control system working starts.

Grid position is calculated every moment using EEPROM which is connected to micro controller. Information is stored in EEPROM so even the power is lost there will be no chances of losing data. This system is attached to a key pad which will work as a keyboard for modifying and deleting mobile numbers. Information is displayed on 16×2 LCD screen. Load controller and Triac drivers are used in this project.
