Wireless Communication and Monitoring on Smartgrid

What is Smart Grid?It is class of technology that brings the

electricity delivery system into 21st century using computer-based remote control and automation.

These systems are made possible by two-way communication technology and computer processing.

They offer many benefits to utilities and consumers -- mostly seen in big improvements in energy efficiency on the electricity grid and in the energy users’ homes and offices.

Smart Grid as a central brain for next generation power grid:

Smart System: Power System + Communication System

Communication in Smart GridHigh-Bandwidth Networks(Backbone) -Fiber Optics, Digital Microwave Radios (very-high data rate 10 GPS and high cost)• Lower-Bandwidth Networks(Access) -Copper paired wire twisted, power line

cables, Wireless systems (high data rate, low cost and low power

consumption:- ZigBee wireless systems)

Why Wireless Sensor Networks in Smart Grid Communication?WSNs are low cost and low power consumingResilience capability to cope up with node

failureMobility of nodes Communicates with a Local Area Network

 or Wide Area Network through a gateway Easy to use and High flexibility

Zigbee in Wireless Sensor NetworkLow cost, Low power consuming and low

data rateNewly developed technology that works on

IEEE standard 802.15.4WSN is composed of ZigBee coordinator,

ZigBee router and ZigBee end deviceStandard ZigBee/IEEE 802.15.4Working Frequency 868/915 MHz, 2.4GHzRange(meter) 30 – 75+ Data Rate 20/40/250 kbps Devices 255 – 65k Power Consumption ~1 m W Cost ($US) ~2 – 5

Hardware components:Xbee Modules These modules are Radio Frequency. They Transmit and receive data wirelessly. • Xbee Shield They are power supply for Xbee modules. Can integrate with other devices like ardu ino.Arduino Uno They are programmable open source mc kit

Hardware Components(Cont…)ConnectPort X2 It helps the Xbee devices to connect with the internet.• It allows the us to monitor and control the devices connected with them from all around the world. • This new technology enabled humans to manage the Zigbee network more

transparent, approachable and easy in practice.
