What is Hybrid Micro-Grid
Advantage Of Hybrid Micro-Grid

3. INTRODUCTION Increasing Power Demand Unable to reach in Rural area
Long Transmission Distance
Failure of Grid System
Fuel crises

4. Grid System
An electrical grid is set up depends on factors such as topology, geography and the level of grid interaction for an area.
Types of Grid System
Radial
Mesh
Looped (Parallel path flow)

5. Disadvantage of Grid System
Low Efficiency
Complex Design
Limitation on long distance Transmission
Blackout Due to Grid Failure
High Transmission Losses
Low Controllability
Low Stability

6. What Is Hybrid Micro-Grid
A group of interconnected loads and distributed generation sources within a clearly defined electrical boundary that acts as a single controllable entity.
Micro-grids themselves are not new, as diesel and gas generator sets have been sold for several decades to power remote applications. These systems are continuously becoming more fuel-efficient as engine combustion and generator technologies improve.

7. Need Of Hybrid Micro-Grid
Micro-grid could be answer to energy crises
Transmission loss highly reduced
Micro-grid result in substantial saving
Reduce CO2 emission
Provide High quality and reliable energy supply to critical loads

8. INTERCONNECTED MICRO-GRID
Practical size of micro-grid is limited to few MVA
For larger loads, it is desirable to interconnect many micro-grids to form larger Micro-grid network called as Power Parks
The advantages of this Micro-grid structure insure greater stability and controllability for Power Parks

9. Micro-grid Operating Mode
Grid Connected Mode
Utility grid is active
Static switch is closed
All grids are being supplied by utility grid

10. Micro-grid Operating Mode
Island Connected Mode
Utility grid is not supplying power
Static switch is open
Feeder A,B & C are supplied by micro source
Feeder D is Dead

11. Advantages Of Hybrid Micro-Grid
Renewable Energy Sources
Energy Storage
System Integration
Low Operating Cost
Compensate Fluctuation
Low Fuel Cost

12. Significant Environmental Benefits
Prevent Utility Grid Failure
Use to supply electricity to Tropical Island
Low operational cost due to short Transmission Distance
Reserved Energy Storage
