Introduction To Microgrid (contd.)(hat is Microgrid)

It is connected to *oth the local generatingunits and the utilit+ grid thus preventing po,eroutages.

E-cess po,er can *e sold to the utilit+ grid.

The Need Of Microgrid

Microgrid could *e the ans,er to our energ+crisis.

Transmission losses gets highl+ reduced.

Microgrid results in su*stantial savings and cutsemissions ,ithout ma>or changes to lifest+les.

Environmental Aspects

Microgrid encourages the use of the rene,a*le

energ+ sources.

arge land use impacts are avoided.

CO' Emissions are reduced.

Conventional Grid vs. Microgrid

EBcienc+ of conventional grid is ver+ lo, as

compared to Microgrid.

arge amount of energ+ in the form of heat is,asted in conventional grid.

Advantages !isadvantages Microgrid AdvantagesIn pea load periods it prevents utilit+ grid failure

*+ reducing the load on the grid.

The use of *oth electricit+ and heat permitted *+the close pro-imit+ of the generator to the user5

there*+ increasing the overall energ+ eBcienc+.

Microgrid can act to mitigate the electricit+ coststo its users *+ generating some or all of itselectricit+ needs.
