2. Contents
• Problem Description
• Changing Regulations and Technology Trends
• Active Network Management
• Use Cases
• North American Experiences
• Discussion

3. A (not so) Long Time Ago…
• Traditional planning rules
that define the “hosting
capacity” of a network
under N-1 criteria
• Challenge
– Can a new control approach
increase the amount of DG a
system can accommodate
– What planning tools are
required to support this new
way of doing things?

10. Technology
ANM Platform Software Components
Application container to host autonomous ANM applications sharing a real time data manager
with sgs comms hub. Typically runs on commodity servers with hot failover redundancy (one as
Main and the other as Standby).
A modular, easy to integrate communications hub performing all data handling and processing
for sgs core via a range of standard industry protocols. Typically runs on commodity servers
(one as Main and the other as Standby)
A distributed software component located at each controlled device providing an interface to and
control of the grid edge device. Implements autonomous fail to safe mechanisms in the event of
non-compliance, loss of communications or abnormal operation.
ANM Software Applications using the Platform
Our ANM products use a combination of the ANM platform and software applications to deliver
specific functionality.

11. Integrated DERMS Platform
• Active network management:
automation layer that handles real-
time control of DER
• Analysis and Optimal
Scheduling: non-real time functions
that empower the operator and
enable a more holistic view of
operations

14. Orkney
Challenge
SSEPD seeking cost effective alternative to grid upgrades to
provide connections for renewable generators: network already at
‘full capacity’. Technical challenge is multiple thermal overloads
on various overhead and subsea cables.
Solution
Non-firm actively managed grid connections for distributed
generation using ANM 100 with an energy storage control
module.
Delivered Benefits
 Operational since November 2009
 Connected 24 MW of new renewable generation capacity to
33 kV grid previously considered to be full
 103% of electricity demand met by renewables in 2013
 Estimated saving of at least £30million
The Orkney Isles are located off the
north cost of Scotland and
interconnected to the main UK
transmission system.
Orkney Isles Background Information
• 70 islands with 20 inhabited
• ~1000 sq km and 21,000 inhabitants
• Winter peak demand of 31 MW
• Summer peak demand of 6 MW
• Installed background generation of 46 MW
• Annual average temperature 80C
• Industry mainly agricultural, fishing and tourism

15. NREL INTEGRATe Project
• Integrate Smart Campus as
part of IEEE 13 bus system
• Modified IEEE 13 bus
system to include
connection of secondary
network
• 3 DER embedded within
secondary network and
other simulated DER

21. Discussion Questions
• Do you envisage integrating a DERMS system in the
near-future?
• If not, how do you plan on integrating DER?
• What are some of the characteristics of the ideal
operational tool that would help you integrate DER?
• Do you anticipate distribution operations (or even
microgrids) integrating with the ISO?
• What challenges do you have in terms of distribution
system planning?

22. Thoughts to leave you with…
• Regulatory model where revenues is dictated by performance
and not by how much capacity you build
• Is integrating DER equivalent to 200% of peak load possible?
• Other Critical National Infrastructure demand the best in real-
time control technologies, why should power systems be
different?
• Think of DERMS as a number of layers. The automation
layer—ANM—is the foundation
• Planners and operators need to be able to model the
behaviour of these systems.
