Who is Smarter Grid Solutions?

• Successful smart grids manage large volumes of fast-changing data. The traditional operator-in-the-loop approach won’t cut it anymore. To resolve the grid challenges of a low carbon world, we need real-time, autonomous, deterministic control technology. That’s why we exist.

• Founded in 2008

• 7,000 sqft HQ in Glasgow with development and test infrastructure

• Offices in New York and London

• Over 50 engineers dedicated to the development and deployment of Active Network Management

• Over 10 years in development in collaboration with utility customers and one of Europe’s leading power systems universities (University of Strathclyde)

What is Active Network Management? What it is not…..

• A part-distributed control technology to manage

distributed energy resources.

• Delivering real-time autonomous deterministic

control providing guaranteed repeatability and time-

bounding of end to end control actions.

• To enable second by second control of distributed

energy resources and grid devices to deliver smart

grid functionality.

• Typical applications include real and reactive power

control, voltage management and energy

balancing.

• SCADA or DMS. However, ANM complements such

systems integrating easily via standard industry protocols

and can further enhance network visibility and grid control.

• Distributed Energy Resource Management System.

ANM complements such systems by providing a robust,

reliable and secure device integration and interaction layer.

• Substation Automation. ANM extends beyond the

substation into the field but leverages existing substation

equipment and communications where possible.

• Distribution Automation. ANM tends to be focused on

power systems constraint problems rather than reliability

improvements but can sometimes be considered a new

type of Distribution Automation application.

A unique perspective on grid management (1)

9

A new form of grid management

- Combining the key attributes of SCADA / DMS and protection / substation automation to deliver autonomous deterministic real-time control over a geographic area of grid, ANM delivers second by second control of Distributed Energy Resources for new smart grid applications.

Peace of mind

- Our ANM technology was developed in collaboration with the planning, control room and protection teams of a major utility meaning that we understand all of the concerns that any utility may have in adopting smart grid technology. Our guaranteed response times, guaranteed repeatability, fail to safe mechanisms and cyber security credentials ensure peace of mind for ANM adopters.

Applications for constraint management

- Within distribution networks the traditional approach has been to build or upgrade the grid to allow passive operation and avoid constraints; Active Network Management provides constraint management options to reduce connection costs, time to connect to the grid and avoid or postpone network reinforcement.

A unique perspective on grid management (2)

10

Fit to connections planning process

- Our own unique range of online and desktop planning tools complement existing connections processes and connection agreements with grid capacity analysis and ANM feasibility assessment allowing ANM to be easily adopted into business operations.

- We have simplified the problem of linking DERs to power systems problems through associative relationships rather than complex mathematical optimisation techniques or use of the connected network model.

Operational experience

- With over 5 years of operational experience and a number of deployed systems with multiple DSOs we understand the practical, operational and power systems challenge that you are likely to face and we know how to address them cost effectively and robust technically.

Where does it take you

- Our products have been developed, and will continue to evolve, to provide the platform for the future DSO. ANM provides the platform to offer new grid services to TSOs, new and improved services to connecting customers and enable easy integration of new technologies (e.g. energy storage and microgrids).

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.
