Design and Development of Internet of things based Smart Grid System

Abstract

This paper describes a Smart Grid architecture implemented with the help of Web of Things .Web of Things
comprise of a set of Web services provided on top of a number of Internet enabled Embedded devices .The Web browser
on any computer can act as an interface to the services provided by these Web of Things. The Embedded devices are
ARM Cortex M3 Processor based devices with Ethernet capabilities. CMSIS Real Time Operating System is used for
process control on each of these embedded devices. LwIP Protocol Stack is implemented on top of each of these devices
so that IP connectivity can be established. The Web interfaces provide us real time information on each of the energy
meters that are installed on site and communicate to the Embedded Internet devices using MODBUS communication
protocol. Real Time energy source scheduling, energy source selection, power connection and disconnection are some of
the services that are provided to an on-line authenticated user. The Embedded Systems lab Infrastructure at the TIFAC
CORE for 3G/4G Communication at National Institute of Science and Technology was used for the hardware testing of
the embedded modules. We were greatly helped by the Software developers at NIST Technology Consultancy Services in
designing the web applications and interfaces for our Web of Thingsarchitecture.
