Smart Grid System

Abstract

Smart Grid System plays an important role and is an effective means of data collection and grid automation that allows substantial saving through the reduction of meter reread, greater accuracy, allows frequent reading, improved billing and customer service, more timely energy profiles and consumption trends updates, and better deployment of human resource. In this project, GSM technology is used to implement an AMR system by means of PIC microcontroller that will read the power consumed by the customers and send it to the power grid. Moreover a small Power grid is also implemented that will be automatically supply the power according to the need of the customer by switching the relays in order to avoid the loss of the extra power. The GSM Energy Profiling System (GEPS) takes advantage of the available GSM infrastructure’s nationwide coverage and the Short Messaging Service (SMS) to transmit energy reading from the digital electric meters to the supplier (server) and receive alerts at the consumer (User) end during the peak hours. Dedicated Single phase meters are installed at the user end. Two meters were implemented in this project. One that measures the power purely by the PIC microcontroller and the second was implemented through the PIC and CS5463 SPI interfacing. The microcontroller after measuring the energy generates a message that contains the energy spent by the customer and this message is then transmitted to the server over the GSM network via the transmission module (Serial GSM Modem). The reception module is also a GSM modem connected to the server system which receives the energy readings transmitted by the consumers and relays them to the server system If commercially employed, this is a comprehensive system which accurately maintains and illustrates energy usage data via an efficient monitoring and profiling system and extensive control by the supplier company.
