What Makes ANM Solutions Useful?
♦ ANM is a distributed, end-to-end autonomous
control solutions for DER integration
♦ ANM bridges protection systems and SCADA
♦ Increased visibility and ANM is scalable:
♦ Device control at PCC
♦ Substation control of multiple DER
♦ Enterprise control of multiple substations
Active Network Management’s ROI
♦ Open standards based integration to EMS/DMS
and field devices
♦ Streamlined DER interconnection with reduced
costs: Increase grid asset utilization
Massive increase in grid hosting capacity: 100-200%
Avoiding or deferring grid upgrades: enhanced assets

The Challenge
Local utility seeking cost-effective alternative to grid
upgrades to provide connections for new renewable
generators: network already at ‘full capacity’
♦ Avoid costly grid upgrades
♦ Increase capacity for renewables
♦ Facilitate interconnection of more
community wind
♦ Limited export capacity to bulk power

Some Suggestions for You and Your Coop
1. Consider alternatives to grid reinforcement
♦ Increasing asset utilization & increasing DG interconnection
♦ Minimize grid modernization costs to entire co-op membership
2. Invest in Information and Communication Technologies
ahead of need – build a scalable platform
♦ The future of the grid depends on data networking and connectivity
3. Start building more flexibility into the organisation that
plan and operate the grid
♦ New skills/jobs, New regulation: See RIIO in the UK and REV in New
York State
4. Incrementally adopt “smart solutions”
♦ See the work of the UK Smart Grid Forum
Conclusions
♦ The way we plan and operate the power grid is changing
♦ New solutions exist to provide more cost effective solutions for distributed and renewable
generation integration: can represent a massive increase in DG interconnection
♦ ANM is an emerging part of the grid management space
♦ E.g. defer reinforcement while still increasing grid hosting capacity – support Co-op
member DG deployments
♦ E.g. increase utilization of existing grid assets – manage total member grid costs
♦ Issues associated with renewables integration, microgrids, EMS/DMS deployment,
resilience and increasing data dependency are common to the UK, EU, USA and Canada
♦ The drivers are common across international projects, but the adoption behavior is driven
by local regimes
♦ Lessons are being learned elsewhere, this learning needs to be visible and accessible
