Other appliances
Transmission SO / TO
Widespread use of a Flexible AC Transmission System
More automated post fault action – enhanced network capability
Greater control interface between TSO and DNO/DSO
Automation of control systems, flow control (QBs, DC links), voltage control, alarm management
Driving assets harder – high temp conductors, on-line rating, sag, short term ratings of circuits and transformers
Flexible risk based SQSS
Balancing between operational complexity and asset investment - Automation versus IS faults / technology failure
DNO (Enabled through Smart Grid comms infrastructure)
Auto post fault action (self healing)
Condition monitoring
Capacity rationing / sharing by directly controlling some demand / embedded generation
Optimisation of embedded and micro-generation / virtual power plants. DSO role?
Electricity Network Efficiency / Reliability Fully using assets through complexity and automation
Operating the system in 2020
How to meet these challenges in the most economic and
sustainable way whilst maintaining security?
How do we cope with
larger plant >1320 MW
when it ‘falls off’ the
system?

National Grid Smart Technology Model
Smart Grid Cyber Security – High Priority
SMART Cyber security high priority for:
Equipment Manufacturers – building in security
Network Design – designing the network to be secure
Network Operations – monitoring, detection, prevention
Two key sources of risk:
deliberate attacks (eg. disgruntled employees, industrial
espionage, acts of terrorists)
inadvertent compromises (eg. user errors, equipment
failures, natural disasters)
SMART Grid Cyber Security - Key Risks
New and complex technology introducing vulnerabilities
Increased number of entry points and paths for potential adversaries to exploit
Communications networks expanded all the way to the home
Radio communication networks vunerabilities
Interconnected networks can introduce common vulnerabilities
More opportunity for introduction of malicious software
Potential for compromise of data confidentiality
Breach of customer privacy.
Smart Technology Centre
Proof-of-Concept
Test and validate the technical solution before we deploy it to our customers.
Center of Excellence
Evaluation, Demonstration, Innovation
Collaborating with several universities
developing academic curricula
workforce training programs
preparing the next generation of engineers and technicians to work with Smart Grid technologies.
Conclusion
We are on the verge of a fundamental shift in the Energy Industry
Smart Grids will be the service platform for future years.
Smart Grids will provide and act as a catalyst for:
current green technologies (e.g. energy efficiency, demand
response)
emerging green technologies (e.g., photovoltaic, energy storage,
plug-in hybrid electric vehicles).
Smart Grids will provide customers with choice
how the electricity they use is generated
greater control over how and when they use energy in their homes
and businesses.
Significant Technology/Security risk need to be managed
