3. INTRODUCTION TO
MICROGRID

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.

5. Microgrid
Components
 Distributed Generation
 Loads
 Immediate storage
 Controller
 Point of Common Coupling

6. Typical Microgrid
 Power is maintained by the microgrid
 Small micro-grids covers 30–50 km radius
 Microgrids are of 5–10 MW

7. Microgrid Sources
 Distributed Energy Resources (DER)
 Bio Gas
 Wind Power
 Solar Power
 Hydro Power

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
