2. Our Agenda Today! Smart Grid Definition Smart Grid Features
South East Smart Grid Project Overview
NIA Learning
In the UK:
We own the high-voltage electricity transmission system in England and Wales and operate the system across Great Britain
We own and operate the high pressure gas transmission system in Britain, and Britain’s largest distribution business delivering gas to almost 11 million homes and businesses
We have a number of unregulated businesses operating in related areas such as liquefied natural gas importation, land remediation, metering and interconnectors
In the US:
We distribute electricity to 3.4 million customers
We provide natural gas to 3.5 million customers
We currently own over 4,000MW of contracted generation
Under a Management Services Agreement, we service 1.1 million customers of the Long Island Power Authority (LIPA)

3. Smart Grid Spectrum Smart Grid Definition:
An electricity network which can intelligently integrate the actions of all users connected to it for efficient and secure operation purpose.
Models of Smart Grid
Smart Transmission
Smart Supply Side
Smart
Homes
Smart Distribution
Energy Clouds
Smart
Cities
There is no currently accepted definition of what a smart grid actually is. But generally:An electricity network that can intelligently integrate the actions of all users connected to it - generators,consumers and those that do both - in order to efficiently deliver sustainable, economic and secure electricity supplies.

4. Smart Grid Features To utilise Demand Side Response
Communication capability across the whole supply chain
To have self healing Grid
Automation at high degrees is possible

5. Smart Grid Features
To enable Wider participation in the grid (i.e. by SMEs)
Interoperability between components
Future growth is less challenging
Easier use of the grid (i.e. by embedded generation)
Uncertainty is managed

6. Transmission and Distribution Networks
South East Smart Grid
Transmission and Distribution Networks
working together

7. T&D Resources – What are they?

8. South East Smart Grid’s Aims
To investigate the feasibility of relying on Distributed Connected Resources to support the transmission network
To recommend necessary technical, commercial, and regulatory mechanisms which enable the roll-out of new service

9. Activities of the Project
A: T&D Modelling
B: T&D Monitoring
C: Offline Trials

10. Siemens Spectrum Power 7

11. Siemens Spectrum Power 7
The TNA suite of applications is configured into 2 main packages:
Grid Analysis Applications
Optimisation Applications
We are still in the trial period and all the results will go into the closure report.

12. South East Smart Grid’s learnings
How do we incorporate Smart Grid concepts into network planning?
Move towards probabilistic planning
Many more cases to analyse
Ensuring consistency in a changing plan
System Studies
Service providers and contract period
Future roll out and degree of confidence
Operational Complexity
Multiple revenue streams for one product (i.e. storage)
Planning criteria
Greater reliance on automated processes
Managing constraint costs
Develop a simulation and test environment
System Operation
South East Smart Grid gives us more tools for planning & operation
