Today’s Topic – Grid Modernization

■ The Path we are on Electrically connected GIS

Automatic model export

Electrically validated switching plans

Optimized feeder configurations

Wide deployment of SCADA

“Life-Story” or conditional based asset management

Efficient deployment of field resources and capital

“Big Data”

■ Collaboration between EDTI and ECE “Assessment and Mitigation of the Impacts of

Distributed Generation on Urban Utilities”

■ Prof. Ing. Petr Musilek, Ph.D., PEng

■ Prof. Hao Liang, Ph.D.

■ Prof. John Salmon, Ph.D., PEng

Studying the Issue: Distributed Energy Systems

16

What does this mean?

Let’s look at the old way of doing things

17

Faulted Circuit (10 years ago)

■ Fuse Blow

■ Calls from customers

■ Line truck dispatched to mid-circuit area

■ Internal memo / email outage notification

■ Patrol / check fault indicators to locate damage

■ Switching to Isolate

■ Restoration / Repair, backup feeder maybe overloaded

■ Calls are still coming in

■ Customer result: Lots out ~45min, a handful for repair (1-2 hrs).

■ Paper record of repair -> drawing backlog

■ Queue for outage report

18

Faulted Circuit (potential future) ■ Fuse Blow

■ AMI last gasp reports all outaged customers to OMS

■ OMS issues alert to system operator and internal pool of recipients

■ DA and RFI report passage of fault to DMS and operators through

SCADA

■ DMS pinpoints fault location to correct circuit branch, and within

200m

■ DMS possibly uses DA devices for FLISR through SCADA,

restoring 50-75% of circuit in less than 120 min.

■ DMS issues recommended switching plan to further isolate

damaged equipment

■ Control sends trouble directly to site to confirm damage & begin

local isolation

■ Calls are starting to come in

■ DMS suggests feeder re-organization to balance load on remaining

feeders, executed through SCADA remote switching by operators

■ Field Repair proceeds

■ DMS suggests optimal switching for feeder return to normal

■ Customer result: Some out for <60sec, some out for ~20min, and a

some out for repair (1-2 hrs).

■ Outage report, statistics, and logging all automatically captured.

Fault scenario can be replayed for analysis, training, or audit.

■ Stressed components are captured by asset management system

integrated with ADMS, and follow action can be taken to mitigate

future potential outages

19

But wait….

■ Technology isn’t everything.

You have to build your organization to succeed.

Technology changes go hand-in-hand with business and organization changes.

20

Business Transformation

■ You need operational

excellence. Silos don’t work

Define and follow our

processes

Skills and training

Fully utilize the benefits of

these technologies

■ You need different skills

than 10 years ago. Ex: GIS modelers

More than Civil / Electrical

Engineers

SCADA, Comms, and analyst

skills can be a big gap.

21

Transformations at EPCOR

■ Some Challenges Knowledge transfer

Training: new staff and

transfer of existing staff

Identifying and acquiring new

skills

Integrating processes and

technologies for maximum

benefit

Keeping everything else rolling

■ Many business units

have been rebuilt

■ New leadership focused

on Operations

■ Skills assessment

■ Procedures
