Power grid

Power grids are larger

conventional and spread out

grids with high voltage power

transmission capabilities.

Microgrid technology can be applied to weak

grids making the network more robust.

Microgrid

Distributed energy resources

and loads that can be

operated in a controlled,

coordinated way either

connected to the main power

grid or in “islanded”* mode.

Microgrids are low or medium voltage grids

without power transmission capabilities

and are typically not geographically spread

out.

Nanogrid

Low voltage grids that typically serve

a single building.

Energy and grid transformationMicrogrid and Power Grid share common features

© ABB Group


Although each segment has its own distinctive

characteristics, there are many common features

between the microgrid and power grid, or smart

grid, of today. Each solution also enables the

other.

be installed in isolated

diesel grid

Microgrid technology can

also be installed in weak

grid locations

Microgrid Potential in IndonesiaExample of microgrid potential (Remote Mining Areas)

Many mining areas (and

other remote industries) in

Indonesia are not

connected to PLN grid

Mining companies in most

cases have to build their

own power plant to supply

their electricity needs

Microgrid technology is also

suitable for this kind of

areas, where they operate

their own diesel power plant
