A microgrid is a small-scale power supply network that is designed to provide power for a small community. It enables local power generation for local loads. It comprises of various small power-generating sources that makes it highly flexible and efficient.
4. What is Microgrid?
It is a small-scale power supply network that is designed to provide power for a small community.
It enables local power generation for local loads.
It comprises of various small power generating sources that makes it highly flexible and efficient.
8. Where it is needed?
Island
Rural Area
Where there is no access of electric energy
9. The Need Of
Microgrid
Microgrid results in
Stability in Voltage & Frequency
Removes Dumsor
Finishes the fear of Blackout and Brownout
too
10. Power Reservation
Power reservation is applied according to IEEE
standard
The Base load is set to be 90% while reserve is
10%
Reserve is utilize when there is brownout (Voltage
dips), to control voltage and frequency in limits
11. Ramping of Power
It is done by diesel generator because it has quick
response
Ramping results in
Maintenance cost
Wear and tear in turbine
CO2 Emission
Remedy is
Storage should be done in batteries.
Minimize the fuel and maintenance cost
Finish CO2 Emission
12. Fuzzy Logic
Controller
It has real values between 0 & 1 in its truth table
Greater efficiency than PID
Less oscillation around the output signal
13. Advantages
It bottles it self in case of fault in NG & provide supply to the loads
In peak load periods it prevents utility grid failure by reducing the load on the grid.
Provides stability in voltage and frequency as well
14. Disadvantages
Synchronous Factors are difficult to meet
More space is required in storing energy in Batteries
Resynchronization with the utility grid is difficult
