Integration of Distribution Management System• Why have a DMS for the LV Network

• Why integrate?

• Sharing data/ CIM Interface

• Presentation of Information

• Interacting with alternative solutions

• Operational Experience

• Management Dashboard / Smart Analytics

DMS – Why use for LV Network

Future

• Substation monitoring – more real-time data

• Active network management solutions – control

• Introduction of meshing / remotely controllable devices

• Increased focus on safe system of control

DMS – Why integrate with GIS?

• Initial creation – scale of network

• Duplication of data / updates / amendments

• For LV need geospatial aspect (schematic alone insufficient)

• Consistency of user information – single source of truth

Monitoring new equipmentMonitoring new equipmentMonitoring new equipmentMonitoring new equipment

• New network equipment itself needs monitoring to ensure that it is safe

• The DMS displays equipment/ system location and status

• Alarms and basic controls are enabled as part of the safety systems

DMS – Dashboard / Smart Analytics

The potential for LV DMS

• Data monitored for planning also has value for operations

• Provision of Management Information as well as alarms

• Use smart analytics to reveal◦ Loss of load

◦ Phase to phase faults

◦ Abnormal operation (backfeeds left on)◦ Split point optimisation

◦ Distance to fault

◦ Overloaded circuits◦ Voltage regulation of HV feeder

◦ Monitoring equipment defects (eg faulty Rogowski sensor)

◦ Other trends ?◦ Other predictions ?

Customer Engagement


Stakeholder Engagement and Customer Vulnerability

Incentive (RIIO/ED1)

• To ensure the ongoing delivery of an efficient network that

embraces wider social and environmental objectives,

electricity distribution network operators need to engage with

a range of stakeholders.

• Key stakeholders will include parties that are affected by, or

represent those affected by, decisions made by the network

companies.

Some of the things we tried

• Letter drops

• Use of the ESC as a call centre

• Knocking on doors – face to face contact

• A high street advisory centre

• Stalls at community events

• Involvement with the local chamber of commerce

• Presenting at school assemblies

• VIP events for trial participants

• Even Newspapers, TV and Radio to promote our Bracknell Low Carbon Day

initiative

Domestic Monitoring- Installation of 250 EPM’s

Visitors per hour: 1.7

(Excluding TVV project visitors)

Percentage of passengers

entering the centre:

0.17-0.23%

Low Carbon Community Advisory Centre LCCAC Stats

LCCAC Learning Outcomes

• If you are going to do it, location

is important

• Reduction in visitors following town

centre refurbishment

• Very expensive

• Stacking of benefits required –

supporting other council services

for instance

• Be explicit about what you offer!

We Do Not SellEnergy!

Low Carbon Day

• Event aim- To promote the message that the time of day in which people use energy has a significant impact on its cost and carbon Intensity

• How?- to encourage a 1 hour reduction in electricity consumption between 5-6pm when Bracknell Primary Substation usually sees its peak

• Marketing/Spreading the message…
