Today’s Grid Smart GridConsumers are uniformed and non-

participative with power system

Informed, involved and active consumers;

demand response and distributed energy

resources

Dominated by central generation: many

obstacles exist for distributed energy

resources interconnection

Many distributed energy resources with plug-

and-play convenience:focus on renewables

Limited wholesale markets, not well

integrated: limited oppurtunities for

consumers

Mature, well-integrated wholesale markets,

growth of new electricity markets consumers

Focus on outages: slow response to power

quality issues

Power quality is a priority with a variety of

quality/price options: rapid resolution of issues

Little integrationof operational data with asset

management: business process silos

Greatly expanded data acquisition of grid

parameters: focus on prevention, minimizing

impact to consumer.

Responds to prevent further damage: focus is

on protecting assets following fault

Resillient to attack and natural disasters with

rapid restoration capabilities.
