A small chipa big change in energy efficiency

Overview of the Smart Grid

Smarter Networks, Bristol, June 23-24th

Guillaume d’Eyssautier, CEO


What is the Smart Grid

• The Smart Grid is a developing network of transmission lines, equipment, controls and new technologies working together to respond immediately to our 21st Century demand for electricity

Smart Homes & Meters

Distribution Intelligence

Grid Operation Centers

Renewable Energy

Plug-In Electric Vehicles

Consumer Engagement


What Makes a Grid “Smart?”

• digital technology that allows for two-way communication between the utility and its customers

• sensing along the transmission lines

• Like the Internet, the Smart Grid will consist of controls, computers, automation, and new technologies and equipment working together


What does a Smart Grid do?The Smart Grid represents an unprecedented opportunity to move the energy industry into a new era of reliability, availability, and efficiency that will contribute to our economic and environmental health.

The benefits associated with the Smart Grid include:

• More efficient transmission of electricity

• Quicker restoration of electricity after power disturbances

• Reduced operations and management costs for utilities, and ultimately

lower power costs for consumers.

• Reduced peak demand, which will also help lower electricity rates

• Increased integration of large-scale renewable energy systems

• Better integration of customer-owner power generation systems,

including renewable energy systems

• Improved security


Challenges for the implementation of a Smart GridHundreds of million of devices will be connected

• Power Generation

• Metering devices

• Sensing devices – Outage detection

• Static Power consuming devices ( Industrial, Commercial, Consumer

Appliances)

• Mobile Power consuming devices ( EVs )

• Etc…

How do we manage all of this ?


Need for a Smart Electricity Network

• Integrated communication infrastructure that enables near real time ,

two-way exchanges of information and power

• AMI that record and communicate detailed information about energy

usage

• Sensors and monitoring systems that check the flow of energy and

performance of the network’s assets

• Automatic controls that detect and repair network problems

• Advanced infrastructure that improve network performance

• IT systems with integrated applications and data analysis

Communication Technology for the Smart Grid - Wireless : Zigbee

•Zigbee support 3 frequencies, the worldwide is 2.4Ghz which have a big attenuation with the concrete walls and high humidity environments.•Big attenuation, means big number or repetitions and hops. Decreasing a lot the theoretical data rate

Communication Technology for the Smart Grid PLC vs Zigbee

• Zigbee was designed for in-home applications starting from a start type network for small number of nodes • to create a big network it requires to add coordinators and routers which are power consuming.•PLC support bigger network with less cost. PLC network is created with the structure of electrical cable and support a higher number of nodes without extra cost and penalties on the data rate and much less power
