Outlines various cyber attacks that are carried out towards the smart grid. Also contains detection and prevention Mechanisms

1. CYBER SECURITY IN
SMART GRID SYSTEM
CHINEDU OPARA (M00560830)

2. OBJECTIVES
• What is a Smart Grid System.
• Components of the Smart Grid System.
• Benefits of Smart Grid System.
• Cyber attacks on Smart Grid Systems
• Defensive Mechanisms

3. WHAT IS SMART GRID SYSTEM (1 – 1)
• A "smart grid" is an electrical grid which includes a variety of operational and
energy measures including smart meters, smart appliances, renewable energy
resources, and energy efficiency resources.

4. WHAT IS SMART GRID SYSTEM (1 – 2)
Power
Grid
ICT
Smart
Grid

5. SMART GRID MODEL (2 – 1)
• Bulk generator: handling and gathering power from renewable and non renewable
energy source in huge quantity.
• Transmission and Distribution: delivers the electricity to and from the customers in
smart grid
• Service Provider. handles all outsider-operations among these domains
• Operations: manages and controls the electricity flow of all other domains.
• Markets: organizes all the members to give administrations like business
administration, wholesaling, retailing and exchanging of vitality administrations.
• Customer.

6. SMART GRID MODEL (2 – 2)

7. BENEFITS OF SMART GRID (3)
• Strengthening the system against security attacks
• Automation of routine maintenance work.
• Enhancing the efficiency of existing system.
• Easy access to power with the click of a button.
• Access to historical data.
• Reduction of energy loss.

8. CYBER SECURITY IN SMART GRID. (4)
• Denial of Service attacks
• Distributed Denial of Service
• Eavesdropping
• Data alteration
• Man-in-the-middle attack
• Identify Spoofing
• Compromised key attack

9. DETECTION AND DEFENSIVE MECHANISMS 5
• Proactive server roaming scheme
• Source tracking.
• Path identifier scheme.
• Using on-screen key pads.

10. CONCLUSION 6
• The Smart Grid System cannot be accomplished without virtualization technology.
• The smart grid system is more secured than conventional Power Grid system.
• More efficient for power generation and supply.
• The Smart Grid system conserves more energy than conventional power grid
systems.
• The Smart Grid system is the future of power transmission and distribution in any
nation.
