           8  Conclusion


           In recent trends microgrid concept has been becoming a popular with the distributed
           generation systems. The electrical system in future has realized some advantages in
           DC transmission system, that has shown the way to the development of DC and AC
           microgrid. Voltage control, frequency control, and power quality are the most important
