Distribution Operations Training Simulator – Storm Simulation and OutageManagement



FunctionSystem Components

Circuits that emanate from the bulk powersource and supply distribution substations. (FERCrefers to these as “distribution”.)

Subtransmission system

Receives power from the transmission systemand transforms it to the subtransmissionvoltage/s.

Bulk power substation

Carries power between systems, and, delivers itto bulk power and distribution substations.

Transmission (Bulk powersystem)

Functional Classification


Functional Classification (contd.)

Distribute power at utilization voltage from thedistribution transformer to the consumer property.

Secondaries and services

Steps down the primary feeder voltage to consumerutilization voltage.

Distribution transformer

Circuit that emanates from a distribution substationto provide a path for power flows to distributiontransformers.

Primary feeder

Receives power from the (sub)transmision circuits andtransforms it to the primary feeder voltage.

Distribution Substation


Why is Distribution operated differently? A Distribution network consists of a very large number

of devices connected radially.

A typical distribution substation will have 4-8 feeders andenergize as many electrical components as an entiretransmission EMS network model

Millions of switching devices, transformers, customerloads,

The focus is on identifying outages and restoring /maintaining supply to customers

A large amount of activity is unplanned

Relatively small amount of networkautomation/monitorinng

High levels of coordination with field crews

Frequent Network changes.

Smarter Grid Vision


The Past and Present

Aging electrical infrastructure of inadequatecapacity are still supplying power though with poorperformance:Transmission: Critically loaded resulting several

significant blackouts.

No new lines were built during the last 20 years

Distribution: Many underground cables and overhead polesinstalled in 1930’s still in service throughout the world.

Human resource imbalance: a very serious issue

Where will the new generation of engineers andprofessors come from?


The Future

Electric power systems becoming larger and more complex in the last 60years.

Unprecedented growth in the demand.

Population growth.

Higher standards demanded by society.

Increased customer expectations.

Distribution systems are no exception.


Global Issues of Concern

Ecology and environment protection is essential

Global warming is one critical example

Next to air and water, energy is the most important need of thesociety

How to achieve balance between all conflicting forces?

Seeking sustainable energy resources is the answer withoutsacrificing air and water quality


Aligned with US DOE definition

Smart Grid - A customer Definition: from DOE

Provide Power Quality for the digitaleconomy

Ensure the reliability and efficiencyof electrical energy supply

Be a significant contributor to preservingour environment

Optimize asset utilization and operateefficiently

Optimize asset use and minimize O&Mcosts while being safer

Enable introduction of new Products,Services & Markets

Fully enable electricity markets

Accommodate all generation & storageoptions

Accommodate a variety of generation &storage options

Operate resiliently against attackand natural disaster

Be robust to security attacks

Enable active participation of ConsumersEmpower and incorporate the consumer

Be Self-Healing: Anticipate & respondeffectively to system disturbancesBe self-healing
