Driving Forces of Change in Electric Power
Rising Greenhouse Gas Emissions (CO2) have the potential to seriously impact the environment and local economies.
Power Outages wreak havoc and cost billions of dollars in lost productivity and revenue.
Security Threats are constant to the electric infrastructure. The physical and cyber security risks, from terrorists and hackers continue to grow exponentially.
Innovative Technology holds significant promise as a “game changer.” Innovation is pervasive across the electricity value chain (from smart appliances to advanced energy storage technologies).
Evolving Standards hold the key to the pace of development. Technical interoperability will be vital to ease of use, adoption rates, cyber security and avoiding stranded costs. The National Institute of Standards and Technology (NIST) is developing these standards in conjunction with the GridWise Architecture Council (GWAC).
What is Smart grid?
A smart grid puts information and communication technology into electricity generation, delivery, and consumption, making systems cleaner, safer, and more reliable and efficient.
U.S. Department of Energy Definition:
A smart grid integrates advanced sensing technologies, control methods, and integrated communications into the current electricity grid.
Smart Grid Benefits
Economic Development
New Jobs: The manufacture, installation, operation and maintenance of the smart grid and its components will create new jobs within the state.
Innovation: Smart grid innovation will enable the growth of business while rewarding customers with valuable new products.
Lower Costs: Costs rise over time and energy is no exception, but the smart grid should provide less costly energy than otherwise would be possible. As such, it will save customers money which can be invested or consumed as they choose.
Wireless Mesh Networking for the Smart Grid Assumptions
Smart meters located at homes and businesses compose a neighborhood area network (NAN).
The NAN architecture is assumed to be a wireless mesh network
Meters communicate bidirectionally with a neighborhood "collector" via multihop routing.
Collectors are connected directly to a utility provider.
Smart meters have a limited range and not all meters can reach a collector directly.
Label switching concept in applied.
A meter may malfunction and interfere with the proper forwarding of packets, e.g., delaying, altering, misrouting, dropping, or misinserting packets.
Resilience Against Single Attacks
A wireless mesh network depends on the cooperation of each node to properly forward packets to their destinations.
If a malicious attacker was located in a path, it could interfere with packet forwarding
Serious Problem: the traditional method to verify receipt of packets is acknowledgements and retransmission time-outs.
Summary
Smart Grid is an emerging technology to provide next generation power grid and is promoted by many governments as a way of addressing energy independence, global warming and emergency resilience issues.
We proposed a solution to address a security issue in wireless mesh networks for smart grid.
Plan to publish a study on the performance and resilience of solution.
