Background
What is ANM?
• Automated, distributed, real time control
system
• Software based solution
• Differs to protection and SCADA systems
• Can manage power system problems
• Thermal Constraints
• Voltage Constraints
• Fault Level
• Controls generator output in real time

Novel areas of the FPP ANM trial
• Integration and coordination of multiple smart solutions -
Quadrature-booster, Dynamic line rating, Automatic Voltage
Controller, RTUs
• Demonstration of generator control with an innovative
commercial arrangement: Capacity quota
• A system integration approach with open standard
communications to integrate multi-vendor devices - IEC 61850
• ANM communications over a purpose-built DNO
communications platform – Radio Frequency mesh

ANM System, Test and Trial Learning
• Integration and trial of novel components of FPP solution:
– Multiple network constraint types
– New controlled devices and technologies
– New ICT enabling technologies trialled
• Significant learning on the applicability and implementation of ANM
control of a wider range of smart network solutions
• Significant move towards standard technical and commercial
solutions for ANM generation connections
33
2011. UK Power Networks. All rights reserved
Key learning outcomes
• Functional and non-functional requirements
• Significance of end to end monitoring
• Easy access to system performance statistics
Specification – Future
deployments
• Learning from both experimental trial and desktop studies.
• Linking with another LCNF Tier 2 project - Energy storage desktop study
Demonstration of FPP Use cases
• Learning in Identifying limitations and areas for improvement – E.g comms issues
• Need to simplify and standardise the ANM - Generator interface design
• Management of cyber security risk at ANM-DG interface
Operational performance
• Understanding of system as a whole – components and relationships
• Monitor, Re-assess and fine tune

Successful deployment of new commercial arrangements and interoperable
smart grid components to deliver faster and cheaper DG connections
Engaged with 50+ DG developers
Interviewed 20
Trialled two DG access principles:
LIFO and Pro–rata capacity quota
Made 40 connection offers:
• 15 accepted, 54.4MW enabled,
£44m savings
Commissioned RF mesh wireless
network for wide area comms
Developed analysis tool for
investment options in DG
dominated networks
Integrated and commissioned smart
devices across 12 sites
Deployed IEC 61850 for
interoperability between solution
components
Installed and commissioned first
quad-booster at 33kV
Key achievements of Flexible Plug and Play
