Smart grid

Smart grid

– Centralized and distributed generation

– Multi-directional power flow

– Intermittent renewable generation

– Consumption integrated in system operation

– Operation based on real time data

New generation units and control possibilities

drive the change in the system

Coping with the increasing installation of wind energy

Fundamentally new challenges for power systems

January 12, 2018 Slide 5

Renewable energies are the key drivers in the evolution of the power system

– Maximum output varies

depending on wind and

sunlight

– No perfect forecast available

for wind and sunlight

– Most of the renewable

energies have little to none

base load capability

Volatile

generation

profile

– Wind and solar installations

are non-synchronous

generation technologies that

connect to grid via power

electronics and have little or

no inertial response capability

Inertial

response

capability

Location

constrained

– Areas with the best resources

are often situated in remote

locations. Tapping into these

resources will require efficient

ways to transport a large

amount of power over long

distances

Modularity

and

distributed

– More production entities

dispersed along the power

system

– Increasing levels of distributed

generation will require new

approaches to regulate and

manage the energy

production and the power

system

Integration of renewable generation – benefits

ABB’s offering for system operators

January 12, 2018 Slide 9

DRM: Demand response management

Grid automation

– Real time monitoring,

analysis and asset

optimization provide the

needed information for

system operator, to further

increase renewable

energies in the grid

Power generation

forecasting and

scheduling

– Good forecasting of

generation and

consumption allows better

planning

– This enables an easier

operation and reduces the

uncertainty of renewable

energies

Virtual Power Plants

– Bundling of small power

plants through

communication and control

enables generators to profit

from the reserve energy

market

– Provide flexibility for

system operators

Demand response

management

– DRM enables load to be

flexible and act upon

signals from operator for

more flexibility

– This reduces the need of

energy curtailments of

renewable energies by

providing further flexibilities

for operation

Microgrids and grid

stabilization solutions

– Managing certain parts of

the grid as an island

provide a viable option for

grids expansion with

renewable energies

– Also equipment use for fully

isolated grids can be used

to enhance the

interconnected grids
