- 3. What is DGs? In distribution levels, many smaller renewable generators (e.g. photovoltaic, fuel cells, micro hydro etc.) will be connected to the networks. These are called distributed generators (DGs) or distributed energy resources (DERS). What is microgrid ? A microgrid is a cluster of loads and microsources operating as a single controllable system that provides power to its local area.
- 4. Introduction This paper proposes a method for power flow control between utility and microgrid through back-to-back converters, which facilitates desired real and reactive power flow between utility and microgrid. In mode-1, specified amount of real and reactive power are shared between the utility and the microgrid through the back-to-back converters. Mode-2 is invoked when the power that can be supplied by the distributed generators (DGs) in the microgrid reaches its maximum limit. In such a case, the rest of the power demand of the microgrid has to be supplied by the utility

- 8. 18 November 2015 8 Advantages Stability of grid system is achieved to great extent The power quality at consumer premises can be improved Economical based operation One of the major advantages of the back-to-back converter connection is that it can provide isolation between the utility and the microgrid, both for voltage and frequency fluctuations.
- 9. FUTURE SCOPE OF WORK Protection of back to back converters in case of fault can be investigated The improvement can be achieved by selection of more appropriate input signals or controller gains Modified drop control can be derived for frequency dependent load Communication can be used to correct the reference quantities The reliability in a microgrid can be improved with the application of back-to- back converters for bidirectional power flow
- 10. Conclusion Power sharing can be achieved with dropping output voltage angels of the converters The quality of distributed generation can be improved significantly by proper reference generation for the DG’S The reliability in a microgrid can be improved with the application of back-to-back converters A low band width communication can also improve power sharing significantly
